Have either of you guys ever been able to hear the U.S. Armed forces station on 873 out of Germany? I forget whether they're 10kw or 50kw (or perhaps even something else.) They own the channel at night in London and adjacent parts of the UK. One night in London I heard "whistling" under the AFRS station, and was wondering if it might have been a het from WWL.
Annoying, because I was trying to listen to NFL playoffs! ;D
