Wonder if any hams have set up any digital ATV. "AHDTV"? We'd need an MPEG-2 encoder feeding an ATSC digital TV modulator, and output it onto the ATV frequency up around 432 or so MHz in our band up there.
DTV repeaters would be interesting. Just demodulate the ATSC RF carrier to the digital MPEG bitstream, then remodulate it to another ATSC carrier. Or just heterodyne the received RF to move it to the new channel without demodulating it. Oh, I'd have a demodulator at the repeater site to use to sense the presense of a signal, to control the transmitter.
