I think it was Ben who was having problems with the radio?
So, I noticed it yesterday too. I live within a few miles of the radio towers, so I get great reception all the time. Yesterday though, I was listening to a station out on the west side of town that's notorious for getting a weak signal out there. Sure enough, there was some static whenever I stepped on the accelerator, enough to be annoying at least. Other stations that had a stronger signal came in fine. Either I hadn't listened to this weaker station before or just hadn't correlated the static to controller operation.
Interestingly, there was a recent thread on the EVDL about radio interference.
