Did anyone catch an UNID with OM "testing testing 12345" etc? Sounds like he was conversing on the phone with someone taking field readings "this is broadcast station..." and State Anthem of the Soviet Union on repeat, played Elvis on repeat a bit, then Bo Diddly, before transmitting in earnest with more 1950s and early 60s tunes before signing off at 06:00 UTC. I have a recording on cassette I need to digitize. I can't give an exact frequency as my radio has a crude (but pretty) analogue dial. The aircheck had a freq announced so will update.
