One piece of advice - if you want to open a recording made in Perseus in
another SDR program like SDR Radio Console, make sure the center frequency
you pick for recording doesn't result in the lowest frequency of the
spectrum being less than 0 kHz - for example if you do a 2000 ks/s
recording with the center frequency at 950 kHz, Perseus software will play
it back but SDR Radio Console will refuse to open up the file (I have had
that happen). I think that SDR Console actually plays back a wider range of
frequencies than Perseus does and doesn't handle frequencies less than 0 as
well as Perseus.
