I was thinking the next big thing (down the road) would be full-duplex, and then you could have two FFT's running :-)
...although maybe that might be better done with a different design (SM2000 ??)... Many years ago we used to have a TAPR 9600 baud repeater in town. It was pretty neat, as it solved the hidden terminal problem, everyone could hear everyone. The neat thing being the bit-regenerator. Rather than wait for the whole packet, it operated at the bit level. I was thinking that maybe an FDM repeater could operate the same way. Receive a symbol, transmit (regenerate) a symbol, loop. That way the repeater doesn't have to know anything about the vocoder or data protocol riding on top of the symbols. With enough carriers to fill the wide-band FM (5 kHz) bandwidth (2400 bps at 50 baud or so). ------------------------------------------------------------------------------ Slashdot TV.
