But I'll bet you any tube radio from the '50s would have no problem. I
quit seriously DXing AM stations when I started working at them. I was
14 at the time.


Not enough selectivity to separate the 9 kHz channels from the Western
Hemisphere 10 kHz channels. And definitely not sensitive enough.

I could get XEROK at noon in Phoenix in my '56 Cadillac. I got WBZ on a
Zenith All-American 5 tube radio in my filthy bedroom in Scottsdale when
I was 12 or 13.


XELO (XEROK) was a 150 kw station; it had a better signal in some parts of
the Phoenix metro than a couple of the local stations.

I've got an issue of Broadcasting from the later 40's with a WBZ ad showing
mail pull from all the states. Noise levels were so low then, and the band
was amazingly less congested that this sort of reception was normal. And
nothing like the conditions and gear required today to get a TP or a TA.
