My best AM DXing came not from the best radio, but from a great antenna.
I had approximately 300 feet long-wire running North-south and another
300 feet going east-west. We lived on a bluff so the antennas had clear sky
view for almost 360 degrees. I had a tuning box set up so I could tune
the effective "direction" and length of the two antennas. In a period
of about 2 years, I QSL'ed each western state, all Canadian Provinces (except
the Maritimes) and a bunch of east-of-Mississippi ("w") stations.

Radios used: Hallicrafters S-38B and a 1959 Rambler permeability tuned
car radio.

I am getting back into the game with a Sony 7600GR and an old BC-314.

Have fun.

Steve
