SSB is just 1/3rd of AM (one sideband, no carrier), and we still have doppler to deal with on the linear sats.... What do you mean by this?

More train Doppler effect. These are sound waves, but the RF FM principle is the same. Not sure why they don't use AM in space, like in aviation...I.e. NO Doppler effect. https://youtu.be/fWX38qjECyE KC9SGV
