HF Frequencies
Dial frequencies based on default tones used in popular packet devices.
30 meters, 300 baud packet, Worldwide

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
