I stumbled across this clip during a recent surfing session and thought it would be of interest here since it's radio related. This has got to be one of the worst cases of radio frequency interference (RFI) I've ever heard of:
The station in question must have been what was then WQEW, today's WFME(AM). Considering it's a 50kw transmitter only about 2 miles away it's not surprising. At one time I'd imagine there was a filter on the line but it might have failed.
