LEO Satellite Frequencies

When I am manually tuning (the vast majority of the time) these are the frequencies I have programmed into my radios. Click the satellite name to expand the frequencies I use.

FM Satellites

For FM satellites, I have each of these frequencies programmed into a unique memory channel for ease of tracking the satellite as it passes by overhead.

Linear Satellites

With linear satellites, there is no channelization so it only makes sense to have a starting set of frequencies to find yourself within the transponder passband, and adjust from there to find a clear space.
