An I/Q version of fldigi using a Flex 5000 as a front-end could demodulate 160 kHz of passband. Of course, the CPU requirements might be a tad high. ;-) > > It would also be interesting to change the sample rate to something larger > so that more signals could be demodulated.

OTOH, if you are going to do that, punt the processing of different portions of the spectrum to different machines. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 [email protected] +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN)
