Very interesting post Chris! After I had turned off my PC, I was still listening to X-FM on 6950 and Redhat was playing "A Girl Like You"-Smithereens, and there was some seemingly co-channel QRM around 0422 UTC. Switching to LSB I had just the Smithereens, but by fine tuning on USB both "A Girl Like You" and "Money For Nothing" could be heard mixing together. The time I wrote down on my notes was 0424 UTC for when the QRM stopped, so maybe our clocks aren't in sync. I thought it might have been something on X-FM's side. Hmmm
