My Signal Link and Sony laptop worked OK unil today. Sequences are normal. Rig key as it should. Receive is adjusted to ZERO db. Just no stations decoded . Went into Setup and K3 and WSPR set t 4800 baud rate. It sequences and keys and modulates OK just no reception (decoding). I see some white or grey indications on the waterfall when it is in receive mode. Any suggestions would be appreciated.
