I'm hearing a signal on 6160 AM here in MD at 1550 UTC. Not super strong, SIO 322 or so. Alternating between test tones and what sounds like Brother Stair. No idea what station this is, CKZN has been off the air for a while now, and he's not something they would transmit anyway. Tests from WBCQ?
1511 WBCQ ID over top the audio.
