There is also a digital VOX option that will put the radio into transmit when audio appears. Saves messing about with the CAT cable.

The drivers install and work without hassle and of all the different USB cables I have tried I found these radiate the least amount of noise. They're not perfect but even when used directly beneath high gain antennas the noise is within acceptable limits.

But no. The Mrs comes in a says the soundbar on the TV is going nuts - volume going up and down, changing settings etc etc etc.
Checked the obvious - VSWR is 1.5:1, my transmissions were being received so I doubt it was being overdriven, station earth is intact and bonded to mains earth.
The soundbar is linked to the TV via an optical cable, so I doubt that is the point of ingress. I placed some clip on ferrites on the power lead with no change.
Time for more head scratching.
