reminds me years ago at whin..we would take the feed from wcor in lebanon for the tennessee football games. we had made up a cue sheet matching john wards..and take our breaks and pot down the feed from them to play our own spots..as well as our own station id..being careful not to have their ID slip over our frequency..that was early in my radio days..not sure if it was legal or not at the time (probabaly not lol) the next year we had a legitimate feed from UT..i remember being told..what ever you do..do not let their calls come over the air..what did i know..just glad to be off the sunday morning preacher feature.. :-*
When I was at WCOR (after working for the blue raider sports network at WMOT

WCOR was an afilliate of the Blue Raider Sports Network. We tuned our radio to 89.5-FM and played the signal over the air. WCOR didn't sell any spots so we just left it on. We got all of WMOT's PSAs and Promos. I think there was even a station ID or 2 from WMOT.
I was there but wasn't running the board.
