When FM station WJQZ Wellsville, NY received their construction permit for 93.5FM, on-air testing started right during the 1985 summer Sporadic "E" season. And two of the DJ's and one of the station's co-owners said that they had a QSL request from Egypt! No, not Egypt, NY either. I certainly remember them doing this testing. I'd be driving around and they would play a Top 40 tune, then live announce, "Conducting tests, conducting tests only. WJQZ Wellsville.", after every tune. They did this for a few months before officially going on-air January 1986. But anyway, with them doing an actual legal ID after every test song, during a Sporadic "E" condition, that QSL claim from Egypt is certainly plausible. Pity, that stations don't do tests like that anymore. They just come on-air, feed satellite programing and roll with that.
And, Bruce Elving FM books are still invaluable. I'm keeping mine. I'd buy up his Toko 110KHz IF filters and put them in AM / FM walkmans, car stereos, home receivers, etc. I still have them in a GE Super Radio, a Sangean ATS-803A, my Bose Accoustic Wave System, and a 1990 Radio Crap headphone radio. When you did that to car stereos, they were a FM DX machine. That headphone radio was unreal and I could walk around listening to FM stations from Toronto, ON, Canada near the PA border. Sadly, that was ripped-off from me. Ahhhhh, the DX memories.
