I know the transponder satellites have been getting smaller and smaller, but
I think an FM transponder in a cubesat would be amazing.

If no FM transponder, maybe some sort of digi-talker similar to SEEDS, where
it has a voice part and then an SSTV part. Either of these would be awesome.

Thanks, KE5GDB
