Get those vacuum tubes warmed up, folks. Both 252 and 171 are nicely audible now.
Confirmed 252 is Alger Chaine 3 from their web stream.
Say, where was this internet thing, back when we only had White's Radio Log? Or if you heard some really odd signal on SW, you could only wait 3 months for the Utility column in Popular Electronics - in the hope someone else heard it also, and took the time to write in.
Admit it - got you other Old Timers thinking back, didn't I?
