- Western Washington State: 144.35 MHz
UHF Networks
- Europe / Africa (IARU region 1):
- Primary 433.800 MHz (heavy ISM interference in many countries)
- Secondary 432.500 MHz since 2008 where ISM is too bad on 433.800 (CT08_C5_Rec32)

- Netherlands (PA): 430.5125 MHz 1200 baud
- Puget Sound, WA: 440.800 MHz 9600 baud
- Kansas / Missouri: 446.175 MHz 1200 baud (primary, with infrastructure)
- Kansas / Missouri: 441.175 MHz 1200 baud (secondary / special event, no infrastructure)
- US Nationwide Proposed: 445.925 ([http://www.aprs.net/vm/DOS/UHFFREQ.HTM proposed by Bob WB4APR])
- New Zealand (ZL): 432.575 MHz 1200 baud allocated but little usage
Six Meters
- United States (IARU region 2):
- Primary Meteor Scatter: 50.660MHz 9600 baud
- Secondary Meteor Scatter: 50.680MHz 1200 baud
- Washington, DC: 50.620MHz 1200 baud (shared with PropNet)
- Alabama: 50.640MHz 9600 baud
HF Frequencies
Dial frequencies based on default tones used in popular packet devices.
30 meters, 300 baud packet, Worldwide
| USB Dial Frequency | Mark Frequency | LSB Dial Frequency | |
|---|---|---|---|
| KAM, MFJ, TinyTrak | 10.147.600 MHz | 10.149.200 MHz | 10.151.000 MHz |
| AEA | 10.147.100 MHz | 10.149.200 MHz | 10.151.500 MHz |
Satellites
| Satellite | Uplink Frequency | Downlink Frequency | Alias | Mode | Status |
|---|---|---|---|---|---|
| ISS | 145.825 MHz | 145.825 MHz | ARISS | 1200 baud AFSK packet | Active |
| PCSAT-2 | 145.825 MHz | 435.275 MHz | ARISS or WIDE2-2 | 1200 baud AFSK packet | Active |
| PCSAT-1 (NO-44) | 145.825 MHz | 145.825 MHz | ARISS | 1200 baud AFSK packet | Daylight Ops Only |
Satellites are subject to doppler shift and you should adjust your uplink/downlink accordingly. Doppler will make the frequency on a LEO shift as follows :
- 2m ±3KHz (FM capture effect negates the need to adjust on this band)
- 70cm ±10KHz
- 13cm ±50KHz
