This was covered, possibly a year ago, possibly on another board.
I remember being there and listening to DAYTIME: WCAU 1210 Philly, WABC, WCBS, WNBC NYC. At night: KYW, WBT, WSM. Critical hours: WOND, WMID Atlantic City, stations from Virginia Beach/Tidewater area and Carolinas. This was in 1971, using an off the shelf, unmolested Panasonic AM/Cassette portable. At that time, I remember only one local AM station, ZFB, I think at 1230 Kc.
I was 15, an Explorer Scout, on a trip, sleeping on the beach in a tent. At the headhouse, there was a massive Hallicrafters rig with two longwire antennae forming an X, and a small A/B box to choose the antenna. I never got to play with it, as I was told the transmitter needed a British license. I did have my US license, Novice and Third Class w/ Broadcast Endorsement. And CB, KCS-4937. They, wisely, were just trying to discourage me!
