[amsat-bb] FM vs Linear Transponders

[Stephen DeVience]

The ground station complexity for using the linear satellites is a real
issue, especially for anyone trying to rove or use a handheld antenna. I've
always found the suggestion to use two FT-817s strapped to your neck very
awkward (and pricey).

I'm starting to think of what would be needed for a handheld-size linear
satellite transceiver. It would have to do SSB on UHF and VHF, and the
Doppler correction could probably be handled by a phone app which would
also provide visual tracking. I know it's a bit more complicated than FM,
but at least you wouldn't need much power. Having separate U/V and V/U
versions would be even easier. It could be a fun project.
