Really cool! Where did these surveys from the final 2 or so minutes come from? I've checked the CFL radio website and these aren't listed there. I'm trying to track down old top 40 surveys for WLOF and WHOO for preservation's sake and it's really been a struggle.
The few I had were a gift from a record/survey collector. I wish you luck in finding some. I have seen them listed on ebay every now and then. Thanks for your interest and your desire to preserve radio past.
