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.
