Just downloaded this software and cannot get any waterfall display when selecting waterfall on the view tab. Tried changing the soundcard settings to all available ones and still got nothing. Have used other software like MultiPSK, etc. with no similar problems, but for some reason it simply will not show a waterfall. I am stumped. It does display the received signals on the left hand band activity screen upon expiration of the transmit period so I know it is receiving signals.
