George, Yes this certainly can be done. We have a couple of options to show the "entire spectrum." One would be to show 0-61MHz and the bin size -- the amount of spectrum in each horizontal pixel -- is just under 30kHz. The other option would be to view 0-122MHz with a bin size of 60kHz. In this case, everything above 70MHz would be significantly rolled off because of our 70MHz LPF. So 70-122MHz would not have much useful data although you could probably see very strong stations such as FM broadcast stations. My inclination is to do 0-61MHz, but I would be interested if there are other opinions about this. They both cost us about the same in terms of FPGA fabric.
