I recently downloaded VarAC and have it operational with my Flex-6000 transceiver. From what I've gathered from how-to video's it is suggested to start calling CQ on a Calling Frequency, then QSY (up or down). My VARA-HF waterfall seems to show the approximate bandwidth of one VarAC QSO. Is there a way to widen the VARA-HF Waterfall to monitor a wider portion of this subband, to switch to monitoring different VarAC QSO's? Butch, KF4HR
