Just curious.......
Anyone know any numbers describing signal isolation between the 2 receivers? Playing with Spectrogram indicates -70dB but can't say how much if any of that is cross talk in the cable or soundcard (SB Audigy). The signal in the sub rx channel of LINE OUT is seen and measured when the sub is 'Off'; if the sub is thereby de-powered and isolated the sigals observed are presumably due to passive leakage??
Not found anything in manuals/elecraft.com and got bored googling for channel isolation in the soundcard....
