With all the connections to the inputs on the break out box disconnected, the waterfall is plain grey, yet there is a noisy waveform and the percentage indicator is showing 10% . I've had a look at the noise floor in winrad and I cant see anything which would cause this. I've noted /dev/dsp is busy if put in transmit mode. ps ax showed artsd running, but killing it makes no difference to the device busy message.. Connecting an audio source with a 1KHz tone ,shows a line in the right place on the waterfall display > Is that the configuration you want?
