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 145.990 MHz 145.800 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!
AO-51 (Echo) 145.860 MHz 435.150 MHz PACB-1 9600 baud FSK packet Active (see schedule)

AO-51 schedule

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 meters +/- 3kHz (FM capture effect negates the need to adjust on this band)

70 cm +/- 10kHz

13 cm + /- 50kHz
