Oh. I though this might be about finding an AMBCB or SWBCB all over the the place on frequencies they should not be on either due to poor transmission facilities or a fault in the front end of the receiver being used.
Back in the day, well it wasn't that long ago, 660 in Dixie had the trashiest transmitter around. These days I think they're under new ownership and I think they made some upgrades as they're certainly not all over the dial.
