That would be neat for sure, and a way to experiment with HD radio as the dude is interested in, and even develop new methods of modulation for the future.
For testing radios and building new circuits, that could be the quantum leap we need, rather than having a piece of test gear for each mode.
How about MTS stereo, and being able to transmit and receive C-QUAM at VHF, which is something I'd want to try.
