[edit] Alternative Input VHF Networks

For low-powered trackers only:

  • Many areas: 144.99 MHz
  • Western Washington State: 144.35 MHz

[edit] 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)
  • Australia (VK): 439.100 MHz 1200 baud (in selected areas)
  • 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 (proposed by Bob WB4APR)
  • New Zealand (ZL): 432.575 MHz 1200 baud allocated but little usage

[edit] 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

[edit] 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

[edit] Satellites

Satellite Uplink Frequency Downlink Frequency Alias Mode Status Schedule
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:

  • 2 m ±3 KHz (FM capture effect negates the need to adjust on this band)
  • 70 cm ±10 KHz
  • 13 cm ±50 KHz
