<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Nets&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for packet activity. There are some existing nets that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot; border=&quot;1&quot;&gt;<br /> &lt;caption&gt;&lt;h1&gt;Current HF Packet Nets&lt;/h1&gt;&lt;/caption&gt;<br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;Name&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Band&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Center Frequency&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Speed&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Protocol&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Usage/notes&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Dial Frequency+Tone pairs&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.103.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 1300 Hz (recommended) | 14.105.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.104.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.102.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 1300 Hz (recommended) | 7.104.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.103.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.596.0 MHz USB, 1000 Hz (recommended) | 3.598.7 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.598.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz USB, 2000 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> &lt;/table&gt;<br /> &lt;/div&gt;<br /> <br /> &lt;br&gt;<br /> &lt;br&gt;<br /> These are proposed nets that allow the operator to retain a presence on the NET105/NET40/NET80 keyboard nets, while using audio tone selection to be able operate node hopping and mail forwarding in independent audio lanes.

For those interested in actual field strength tests, [https://www.w8ji.com/nvis_n_v_i_s_antenna.htm W8JI's NVIS page] shows the height to performance numbers. <br /> For a quick reference, here are optimal antenna heights per band. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table vallign=&quot;TOP&quot; border=&quot;1&quot;&gt;<br /> &lt;tr&gt;<br /> &lt;td allign=&quot;center&quot;&gt;Band&lt;/td&gt;<br /> &lt;td allign=&quot;center&quot;&gt;Height&lt;/td&gt;<br /> &lt;/tr&gt;<br /> &lt;tr&gt;<br /> &lt;td allign=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td allign=&quot;center&quot;&gt;8.25-16.5ft&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td allign=&quot;center&quot;&gt;30M&lt;/td&gt;<br /> &lt;td allign=&quot;center&quot;&gt;11.5-23ft&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td allign=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td allign=&quot;center&quot;&gt;16.5-33ft&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td allign=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td allign=&quot;center&quot;&gt;33-65ft&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;/table&gt;<br /> &lt;/div&gt;<br /> <br /> Conventional wisdom suggest NVIS primarily happens below about 10 MHz, though [https://ohiopacket.org/images/tmp/20M_NVIS.png real world observation] on 20m with a vertical magnetic loop at 3ft above the ground has yielded contacts well beyond groundwave, but far too short for lower angle skywave, leaving us well within NVIS ranges. More experimentation may be needed to test it's feasibility on modes which require stronger signals.</div>

<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Nets&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for packet activity. There are some existing nets that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot; border=&quot;1&quot;&gt;<br /> &lt;caption&gt;&lt;h1&gt;Current HF Packet Nets&lt;/h1&gt;&lt;/caption&gt;<br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;Name&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Band&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Center Frequency&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Speed&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Protocol&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Usage/notes&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Dial Frequency+Tone pairs&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.103.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 1300 Hz (recommended) | 14.105.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.104.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.102.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 1300 Hz (recommended) | 7.104.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.103.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.596.0 MHz USB, 1000 Hz (recommended) | 3.598.7 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.598.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz USB, 2000 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> &lt;/table&gt;<br /> &lt;/div&gt;<br /> <br /> &lt;br&gt;<br /> &lt;br&gt;<br /> These are proposed nets that allow the operator to retain a presence on the NET105/NET40/NET80 keyboard nets, while using audio tone selection to be able operate node hopping and mail forwarding in independent audio lanes.

Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run ARDOP, VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz).

<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Nets&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for packet activity. There are some existing nets that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot; border=&quot;1&quot;&gt;<br /> &lt;caption&gt;&lt;h1&gt;Current HF Packet Nets&lt;/h1&gt;&lt;/caption&gt;<br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;Name&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Band&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Center Frequency&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Speed&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Protocol&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Usage/notes&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Dial Frequency+Tone pairs&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.103.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 1300 Hz (recommended) | 14.105.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.104.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.102.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 1300 Hz (recommended) | 7.104.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.103.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.596.0 MHz USB, 1000 Hz (recommended) | 3.598.7 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.598.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz USB, 2000 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> &lt;/table&gt;<br /> &lt;/div&gt;<br /> <br /> &lt;br&gt;<br /> &lt;br&gt;<br /> These are proposed nets that allow the operator to retain a presence on the NET105/NET40/NET80 keyboard nets, while using audio tone selection to be able operate node hopping and mail forwarding in independent audio lanes.

The frequencies/tones selected exist just inside the [https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-97/subpart-C/section-97.221 Part 97.221 Automatic Digital Control Station] (ADCS) band edges in an effort to minimize co-channel interference. The dial frequencies are outside the ADCS range, but the audio tones are inside the range. Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run ARDOP, VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz).

<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Nets&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for packet activity. There are some existing nets that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot; border=&quot;1&quot;&gt;<br /> &lt;caption&gt;&lt;h1&gt;Current HF Packet Nets&lt;/h1&gt;&lt;/caption&gt;<br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;Name&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Band&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Center Frequency&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Speed&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Protocol&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Usage/notes&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Dial Frequency+Tone pairs&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.103.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 1300 Hz (recommended) | 14.105.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.104.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.102.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 1300 Hz (recommended) | 7.104.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.103.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.596.0 MHz USB, 1000 Hz (recommended) | 3.598.7 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.598.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz USB, 2000 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> &lt;/table&gt;<br /> &lt;/div&gt;<br /> <br /> &lt;br&gt;<br /> &lt;br&gt;<br /> These are proposed nets that allow the operator to retain a presence on the NET105/NET40/NET80 keyboard nets, while using audio tone selection to be able operate node hopping and mail forwarding in independent audio lanes.

The frequencies/tones selected exist just inside the Automatic Digital Control Station (ADCS) band edges in an effort to minimize co-channel interference. The dial frequencies are outside the ADCS range, but the audio tones are inside the range. Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run ARDOP, VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz). More importantly, it keeps the VARA and/or Mercury HF modems within the ADCS subband to allow legal automatic operation.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table

<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Nets&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for packet activity. There are some existing nets that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot; border=&quot;1&quot;&gt;<br /> &lt;caption&gt;&lt;h1&gt;Current HF Packet Nets&lt;/h1&gt;&lt;/caption&gt;<br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;Name&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Band&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Center Frequency&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Speed&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Protocol&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Usage/notes&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Dial Frequency+Tone pairs&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.103.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 1300 Hz (recommended) | 14.105.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.104.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.102.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 1300 Hz (recommended) | 7.104.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.103.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.596.0 MHz USB, 1000 Hz (recommended) | 3.598.7 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.598.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz USB, 2000 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> &lt;/table&gt;<br /> &lt;/div&gt;<br /> <br /> &lt;br&gt;<br /> &lt;br&gt;<br /> These are proposed nets that allow the operator to retain a presence on the NET105/NET40/NET80 keyboard nets, while using audio tone selection to be able operate node hopping and mail forwarding in independent audio lanes.

The frequencies/tones selected exist just inside the Automatic Digital Control Station (ADCS) band edges in an effort to minimize co-channel interference. The dial frequencies are outside the ADCS range, but the audio tones are inside the range. Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz). More importantly, it keeps the VARA and/or Mercury HF modems within the ADCS subband to allow legal automatic operation.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table

<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Nets&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for packet activity. There are some existing nets that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot; border=&quot;1&quot;&gt;<br /> &lt;caption&gt;&lt;h1&gt;Current HF Packet Nets&lt;/h1&gt;&lt;/caption&gt;<br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;Name&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Band&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Center Frequency&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Speed&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Protocol&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Usage/notes&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Dial Frequency+Tone pairs&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.103.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 1300 Hz (recommended) | 14.105.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.104.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.102.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 1300 Hz (recommended) | 7.104.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.103.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.596.0 MHz USB, 1000 Hz (recommended) | 3.598.7 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.598.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz USB, 2000 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> &lt;/table&gt;<br /> &lt;/div&gt;<br /> <br /> &lt;br&gt;<br /> &lt;br&gt;<br /> These are proposed nets that allow the operator to retain a presence on the NET105/NET40/NET80 keyboard nets, while using audio tone selection to be able operate node hopping and mail forwarding in independent audio lanes.

The frequencies/tones selected exist just inside the Automatic Digital Control Station (ADCS) band edges in an effort to minimize co-channel interference. The dial frequencies are outside the ADCS range, but the audio tones are inside the range. Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz). More importantly, it keeps the VARA and/or Mercury HF modems within the ADCS subband to allow legal automatic operation.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table

<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Nets&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for packet activity. There are some existing nets that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot; border=&quot;1&quot;&gt;<br /> &lt;caption&gt;&lt;h1&gt;Current HF Packet Nets&lt;/h1&gt;&lt;/caption&gt;<br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;Name&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Band&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Center Frequency&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Speed&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Protocol&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Usage/notes&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Dial Frequency+Tone pairs&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.103.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 1300 Hz (recommended) | 14.105.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET105&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;20M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.104.3&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;14.102.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.102.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 1300 Hz (recommended) | 7.104.0 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET40&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;40M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.103.3 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;7.101.0 MHz USB, 2300 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;AX.25/FX.25&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.596.0 MHz USB, 1000 Hz (recommended) | 3.598.7 MHz LSB, 1700 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> <br /> &lt;tr&gt;<br /> &lt;td align=&quot;center&quot;&gt;NET80&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;80M&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.598.0 MHz&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;300 Baud&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;IL2P&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;Keyboard to Keyboard&lt;/td&gt;<br /> &lt;td align=&quot;center&quot;&gt;3.597.0 MHz USB, 2000 Hz&lt;/td&gt;<br /> &lt;/tr&gt;<br /> &lt;/table&gt;<br /> &lt;/div&gt;<br /> <br /> &lt;br&gt;<br /> &lt;br&gt;<br /> These are proposed nets that allow the operator to retain a presence on the NET105/NET40/NET80 keyboard nets, while using audio tone selection to be able operate node hopping and mail forwarding in independent audio lanes.

The frequencies/tones selected exist just inside the Automatic Digital Control Station (ADCS) band edges in an effort to minimize co-channel interference. The dial frequencies are outside the ADCS range, but the audio tones are inside the range. Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz). More importantly, it keeps the VARA and/or Mercury HF modems within the ADCS subband to allow legal automatic operation.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table

<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Nets&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for node hopping and mail forwarding. There are some existing networks that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot;

The frequencies/tones selected exist just inside the Automatic Digital Control Station (ADCS) band edges in an effort to minimize co-channel interference. The dial frequencies are outside the ADCS range, but the audio tones are inside the range. Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz).

<p>Opadmin: </p> <hr /> <div>&lt;h1&gt;HF Networks&lt;/h1&gt;<br /> The following index has been created to track various efforts to utilize the HF bands for node hopping and mail forwarding. There are some existing networks that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. <br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot;

The frequencies/tones selected exist just inside the Automatic Digital Control Station (ADCS) band edges in an effort to minimize co-channel interference. The dial frequencies are outside the ADCS range, but the audio tones are inside the range. Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz). More importantly, it keeps the VARA and/or Mercury HF modems within the ADCS subband to allow legal automatic operation.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table

<p>Opadmin: </p> <hr /> <div>The following index has been created to track various efforts to utilize the HF bands for node hopping and mail forwarding. There are some existing networks that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided. With the overarching goal of linking systems statewide, we must also employ antenna systems that favor [https://en.wikipedia.org/wiki/Near_vertical_incidence_skywave NVIS] type propagation.

Remote/unattended stations may wish to permanently reside here while local/attended may choose to QSY here for forwarding only. If you choose to run VARA and/or Mercury HF modems on the proposed dial frequencies, it is ''imperative'' that the bandwidth is limited to 500 Hz. This preserves the 250 Hz buffer between AX.25/FX.25 space tone (1100 Hz) and IL2P mark tone (1900 Hz). More importantly, it keeps the VARA and/or Mercury HF modems within the ADCS subband to allow legal automatic operation.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table

<p>Opadmin: </p> <hr /> <div>The following index has been created to track various efforts to utilize the HF bands for node hopping and mail forwarding. There are some existing networks that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot;

Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br /> &lt;table valign=&quot;TOP&quot;

<p>Opadmin: </p> <hr /> <div>The following index has been created to track various efforts to utilize the HF bands for node hopping and mail forwarding. There are some existing networks that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB.

<p>Opadmin: </p> <hr /> <div>The following index has been created to track various efforts to utilize the HF bands for node hopping and mail forwarding. There are some existing networks that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB.

<p>Opadmin: </p> <hr /> <div>The following index has been created to track various efforts to utilize the HF bands for node hopping and mail forwarding. There are some existing networks that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match. The seeming standard for HF IL2P seems to be USB. For compatibility reasons, it is suggested to run USB for both AX.25/FX.25 and IL2P. This also aligns with VARA, ARDOP and Mercury modems using USB. Traditionally, AX.25 HF packet was LSB by convention, but can support both. For those running hardware based TNCs that do not support IL2P and have fixed tones at 1600:1800 Hz (1700 Hz center), LSB frequencies are provided.<br /> <br /> &lt;div id=&quot;main&quot;&gt;<br />

<p>Opadmin: </p> <hr /> <div>The following index has been created to track various efforts to utilize the HF bands for node hopping and mail forwarding. There are some existing networks that are primarily focused on casual operating, keyboard to keyboard messaging for personal mail delivery. Due to the nature of AFSK and SSB, it is possible to have many combinations of VFO dial frequency with audio tone selection. Please see [http://wa8lmf.net/aprs/SSB_Frequencies.htm WA8LMF's excellent article] on their relationship. It is also possible to run multiple, concurrent modems as long as their audio pass range fits within the radio's SSB filter. These ranges can vary, but generally runs around 300-3000 Hz. The two most popular protocols are AX.25/FX.25 (compatible) and IL2P. The AX.25/FX.25 protocols use NRZI encoding, which means USB and LSB can communicate as long as the center frequencies match. The IL2P protocol uses NRZ encoding, which means sideband selection must match.

Opadmin https://ohiopacket.org/index.php?title=BBS_Hierarchical_Routing_Addresses&diff=3304 2025-05-27T15:14:28Z

<p>Opadmin: </p> <hr /> <div>When personal packet messages are sent from BBS to BBS, each system in the delivery &quot;chain&quot; has to have an indication as to which direction to send a given message. Before the advent of Internet based links or utilization of HF forwarding, the only option of moving messages long distances were by leveraging VHF and UHF links.<br /> <br /> The answer to this requirement is what is known as the hierarchical routing addresses. This varies slightly from state to state and country to country, but the basic breakout is:<br /> <br /> CALLSIGN.#REGION.STATE.COUNTRY.CONTINENT<br /> <br /> For a BBS system located in Central Ohio (Columbus area), the address would be<br /> <br /> CALLSIGN.#CMH.OH.USA.NOAM<br /> <br /> The breakout is:&lt;br&gt;<br /> CALLSIGN - This is the callsign of the BBS system itself&lt;br&gt;<br /> &lt;nowiki&gt;#CMH&lt;/nowiki&gt; - The region within the state where the BBS resides&lt;br&gt;<br /> OH - The state which the BBS resides&lt;br&gt;<br /> USA - The country which the state resides&lt;br&gt;<br /> NOAM - The continent which the country resides&lt;br&gt;<br /> <br /> From what I can recall and find, the 5 major cities within Ohio each had their own regional designators:<br /> <br /> &lt;nowiki&gt;#CIN&lt;/nowiki&gt;.OH.USA.NOAM (Cincinnati)&lt;br&gt;<br /> &lt;nowiki&gt;#CLE&lt;/nowiki&gt;.OH.USA.NOAM (Cleveland)&lt;br&gt;<br /> &lt;nowiki&gt;#CMH&lt;/nowiki&gt;.OH.USA.NOAM (Columbus)&lt;br&gt;<br /> &lt;nowiki&gt;#DAY&lt;/nowiki&gt;.OH.USA.NOAM (Dayton)&lt;br&gt;<br /> &lt;nowiki&gt;#TOL&lt;/nowiki&gt;.OH.USA.NOAM (Toledo)&lt;br&gt;<br /> <br /> For the areas which did not fall within the areas, there are more general designators.<br /> <br /> &lt;nowiki&gt;#EOH&lt;/nowiki&gt;.OH.USA.NOAM (East Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#NOH&lt;/nowiki&gt;.OH.USA.NOAM (North Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#SOH&lt;/nowiki&gt;.OH.USA.NOAM (South Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#WOH&lt;/nowiki&gt;.OH.USA.NOAM (West Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#NEOH&lt;/nowiki&gt;.OH.USA.NOAM (Northeast Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#NWOH&lt;/nowiki&gt;.OH.USA.NOAM (Northwest Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#SEOH&lt;/nowiki&gt;.OH.USA.NOAM (Southeast Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#SWOH&lt;/nowiki&gt;.OH.USA.NOAM (Southwest Ohio)&lt;br&gt;<br /> <br /> Similarly to email, the actual packet mail address is simply the target recipients callsign@BBS.#REGION.STATE.COUNTRY.CONTINENT. For myself, this is<br /> <br /> KB8UVN@KB8UVN.#CMH.OH.USA.NOAM<br /> <br /> The idea behind the hierarchical routing is being able to look at the full address and knowing how to route it. You could use everything right of the callsign to route the message. The system operator would not need to know all BBSes everywhere, simply know who is the next &quot;hop&quot; to get it there.<br /> <br /> In our first example, we will have a hypothetical BBS system located in Cleveland, Ohio under the callsign of KD8CLE. The full hierarchical address is<br /> <br /> KD8CLE.#CLE.OH.USA.NOAM<br /> <br /> The originating BBS will start in Columbus, under the callsign of KB8UVN. The full hierarchical address is<br /> <br /> KB8UVN.#CMH.OH.USA.NOAM<br /> <br /> When the message arrives at KB8UVN.#CMH.OH.USA.NOAM (either entered directly by a local user or forwarded by a neighboring BBS system), it will inspect the full address. In this example, the message is intended for our theoretical BBS system operator, KD8CLE.#CLE.OH.USA.NOAM. The full &quot;to&quot; address is:<br /> <br /> KD8CLE@KD8CLE.#CLE.OH.USA.NOAM<br /> <br /> On inspection of the content to the right of the &quot;@&quot; symbol, we know the BBS is within the same continent (NOAM), same country (USA), same state (OH), but in a different region (#CLE). A properly configured system will not necessarily know how to get directly to KD8CLE.#CLE.OH.USA.NOAM, but it will know which &quot;neighbor&quot; is the next logical hop. The KB8UVN.#CMH.OH.USA.NOAM system looks at it's list of forwarding partners and determines the next best &quot;hop&quot; to get up to Cleveland is located in Ashland, Ohio. The KB8UVN BBS establishes a packet link up into Ashland (W3YXS.#NEOH.OH.USA.NOAM) and delivers the message destined for the KD8CLE.#CLE.OH.USA.NOAM. At this point, the KB8UVN BBS has done it's part and the responsibility of passing the message falls on the system operator of W3YXS.#NEOH.OH.USA.NOAM. In this example, the W3YXS.#NEOH.OH.USA.NOAM is a forwarding partner with KD8CLE.#CLE.OH.USA.NOAM. On the next forwarding cycle, the W3YXS BBS system establishes an outbound packet connection, likely leveraging a few node &quot;hops&quot;, probably crossing multiple frequencies and possibly baudrates to ultimately deliver the message destined for KD8CLE@KD8CLE.#CLE.OH.USA.NOAM.<br /> <br /> In the next example, we will have a message originating in Central Ohio, but destined for a theoretical user (AA5XX) at the KC5EIV BBS system located in the Dallas/Fort Worth area in Texas. When the message is sent, the target full address is:<br /> <br /> AA5XX@KC5EIV.#DFW.TX.USA.NOAM<br /> <br /> Looking at the address to the right of the &quot;@&quot; symbol, the originating BBS system in Central Ohio knows the message must go south and/or west to land in Texas. Depending on the available neighbors, this would likely result in a connection to Springfield, Dayton or Cincinnati or other #SWOH, #SOH or #WOH BBS system. The current infrastructure does not have a neighboring BBS system to take this message. It just so happens that a 30m WINMOR link exists a local packet node on the north side of Columbus (CMHSW2:KB8UVN-5) down to the N5MDT BBS system in Eastgate, Texas (N5MDT.#SETX.TX.USA.NOAM). In the interest of getting the message delivered, a BBS forwarding session is establish and the message is passed. The next routing decision falls into the hands of the system operator of N5MDT. Since Eastgate, Texas is in southeast Texas, the N5MDT BBS will then try to utilize VHF and UHF links to head the needed north and west direction to land in the Dallas/Fort Worth area.<br /> <br /> There are a few key points to keep in mind:<br /> <br /> * The further away from the ultimate destination, the further right of the @ is used.

<p>Opadmin: </p> <hr /> <div>When personal packet messages are sent from BBS to BBS, each system in the delivery &quot;chain&quot; has to have an indication as to which direction to send a given message. Before the advent of Internet based links or utilization of HF forwarding, the only option of moving messages long distances were by leveraging VHF and UHF links.<br /> <br /> The answer to this requirement is what is known as the hierarchical routing addresses. This varies slightly from state to state and country to country, but the basic breakout is:<br /> <br /> CALLSIGN.#REGION.STATE.COUNTRY.CONTINENT<br /> <br /> For a BBS system located in Central Ohio (Columbus area), the address would be<br /> <br /> CALLSIGN.#CMH.OH.USA.NOAM<br /> <br /> The breakout is:&lt;br&gt;<br /> CALLSIGN - This is the callsign of the BBS system itself&lt;br&gt;<br /> &lt;nowiki&gt;#CMH&lt;/nowiki&gt; - The region within the state where the BBS resides&lt;br&gt;<br /> OH - The state which the BBS resides&lt;br&gt;<br /> USA - The country which the state resides&lt;br&gt;<br /> NOAM - The continent which the country resides&lt;br&gt;<br /> <br /> From what I can recall and find, the 5 major cities within Ohio each had their own regional designators:<br /> <br /> &lt;nowiki&gt;#CIN&lt;/nowiki&gt;.OH.USA.NOAM (Cincinnati)&lt;br&gt;<br /> &lt;nowiki&gt;#CLE&lt;/nowiki&gt;.OH.USA.NOAM (Cleveland)&lt;br&gt;<br /> &lt;nowiki&gt;#CMH&lt;/nowiki&gt;.OH.USA.NOAM (Columbus)&lt;br&gt;<br /> &lt;nowiki&gt;#DAY&lt;/nowiki&gt;.OH.USA.NOAM (Dayton)&lt;br&gt;<br /> &lt;nowiki&gt;#TOL&lt;/nowiki&gt;.OH.USA.NOAM (Toledo)&lt;br&gt;<br /> <br /> For the areas which did not fall within the areas, there are more general designators.<br /> <br /> &lt;nowiki&gt;#EOH&lt;/nowiki&gt;.OH.USA.NOAM (East Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#NOH&lt;/nowiki&gt;.OH.USA.NOAM (North Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#SOH&lt;/nowiki&gt;.OH.USA.NOAM (South Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#WOH&lt;/nowiki&gt;.OH.USA.NOAM (West Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#NEOH&lt;/nowiki&gt;.OH.USA.NOAM (Northeast Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#NWOH&lt;/nowiki&gt;.OH.USA.NOAM (Northwest Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#SEOH&lt;/nowiki&gt;.OH.USA.NOAM (Southeast Ohio)&lt;br&gt;<br /> &lt;nowiki&gt;#SWOH&lt;/nowiki&gt;.OH.USA.NOAM (Southwest Ohio)&lt;br&gt;<br /> <br /> Similarly to email, the actual packet mail address is simply the target recipients callsign@BBS.#REGION.STATE.COUNTRY.CONTINENT. For myself, this is<br /> <br /> KB8UVN@KB8UVN.#CMH.OH.USA.NOAM<br /> <br /> The idea behind the hierarchical routing is being able to look at the full address and knowing how to route it. You could use everything right of the callsign to route the message. The system operator would not need to know all BBSes everywhere, simply know who is the next &quot;hop&quot; to get it there.<br /> <br /> In our first example, we will have a hypothetical BBS system located in Cleveland, Ohio under the callsign of KD8CLE. The full hierarchical address is<br /> <br /> KD8CLE.#CLE.OH.USA.NOAM<br /> <br /> The originating BBS will start in Columbus, under the callsign of KB8UVN. The full hierarchical address is<br /> <br /> KB8UVN.#CMH.OH.USA.NOAM<br /> <br /> When the message arrives at KB8UVN.#CMH.OH.USA.NOAM (either entered directly by a local user or forwarded by a neighboring BBS system), it will inspect the full address. In this example, the message is intended for our theoretical BBS system operator, KD8CLE.#CLE.OH.USA.NOAM. The full &quot;to&quot; address is:<br /> <br /> KD8CLE@KD8CLE.#CLE.OH.USA.NOAM<br /> <br /> On inspection of the content to the right of the &quot;@&quot; symbol, we know the BBS is within the same continent (NOAM), same country (USA), same state (OH), but in a different region (#CLE). A properly configured system will not necessarily know how to get directly to KD8CLE.#CLE.OH.USA.NOAM, but it will know which &quot;neighbor&quot; is the next logical hop. The KB8UVN.#CMH.OH.USA.NOAM system looks at it's list of forwarding partners and determines the next best &quot;hop&quot; to get up to Cleveland is located in Ashland, Ohio. The KB8UVN BBS establishes a packet link up into Ashland (W3YXS.#NEOH.OH.USA.NOAM) and delivers the message destined for the KD8CLE.#CLE.OH.USA.NOAM. At this point, the KB8UVN BBS has done it's part and the responsibility of passing the message falls on the system operator of W3YXS.#NEOH.OH.USA.NOAM. In this example, the W3YXS.#NEOH.OH.USA.NOAM is a forwarding partner with KD8CLE.#CLE.OH.USA.NOAM. On the next forwarding cycle, the W3YXS BBS system establishes an outbound packet connection, likely leveraging a few node &quot;hops&quot;, probably crossing multiple frequencies and possibly baudrates to ultimately deliver the message destined for KD8CLE@KD8CLE.#CLE.OH.USA.NOAM.<br /> <br /> In the next example, we will have a message originating in Central Ohio, but destined for a theoretical user (AA5XX) at the KC5EIV BBS system located in the Dallas/Fort Worth area in Texas. When the message is sent, the target full address is:<br /> <br /> AA5XX@KC5EIV.#DFW.TX.USA.NOAM<br /> <br /> Looking at the address to the right of the &quot;@&quot; symbol, the originating BBS system in Central Ohio knows the message must go south and/or west to land in Texas. Depending on the available neighbors, this would likely result in a connection to Springfield, Dayton or Cincinnati or other #SWOH, #SOH or #WOH BBS system. The current infrastructure does not have a neighboring BBS system to take this message. It just so happens that a 30m WINMOR link exists a local packet node on the north side of Columbus (CMHSW2:KB8UVN-5) down to the N5MDT BBS system in Eastgate, Texas (N5MDT.#SETX.TX.USA.NOAM).
