Where to find Packet Activity

Listen to packets at 300 baud packet (HF)

Listen to packets sent at 1200 baud (VHF/UHF)

For APRS packet activity:

In the US and some other countries, the primary nationwide APRS frequency is 144.39 MHz. In Europe, Australia and other parts of the world, it is 144.80 MHz.

There is also some HF APRS activity, primarily around 10.151.51 MHz LSB (North America) and 14.105.51 MHz LSB (except in ITU Region 3). The Operating Modes page on this website has more information about HF packet activity at 300 baud.

 

For BBS, Packet Cluster, Networks and Packet Conversations:

In the US, most packet activity is found on the 2 meter band:

2 meters:  Baud rate is typically 1200. he most common frequencies are 144.93, 145.01, 145.03, 145.05, 145.07, 145.09 and 145.53 MHz, but you may find it anywhere between 144.90-145.10 and between 145.50-145.80. The baud rate used is 1200.

1.25 meters (220 band): most packet heard in this band will be "backbone" traffic between network nodes and BBSs. It will not be an access band for users.

70 cm (440 band):  The packet allocation for the band (mixed mode segment) is 432.10-432.30 and 432.40-433.00. Packet should not be used below 432.00. By local option, packet could also be used from 442.000 to 445.950 and 446.100 to 448.000. Baud rate may be 9600 or 1200.

Note:
some packet heard in this band may be "backbone" traffic between network nodes and BBSs. If so, there will be no user access to nodes or BBBs on the frequency.

For HF Packet:

HF BBS: In North America, you can find the "Network 105" BBS on 14.105 MHz LSB. Baud rate is 300.

HF Conversations:

Band 

Suggested Frequencies - all LSB / Lower Side Band*

(channel centers = RF between the 2 tones)

80

3580-3635, priority at 3620-3635

40

7035-7050, priority at 7040-7050
and 7100-7120 with Americas

30

10.130-10.150, priority at 10.140-10.150

20

14.070-14.112, except 14.100 (beacons);
 priority at 14.095-14.0995

17

18.100-18.110, priority 18.104-18.110

15

21.070-21.125, priority 21.090-21.125

12

24.920-24.930, priority 24.925-24.930

10

28.070-28.189, priority 28.120-28.189

 

* AGWPE tones have a center frequency of  2210 Hz, so for LSB you would set your radio dial + 2210 Hz higher than the frequencies listed above. (For LSB, remember that the greater the frequency shift, the lower the resulting LSB frequency.)
