AM DX logs here!
Nov15 03:05 529 LYQ NDB out of Manchester, TN booming in tonight with CW ident repeating over CIAO Toronto. Was listening to them in the car. - de k9rzz wi (this NDB is actually at the WWRB shortwave transmitter site).
It's an aeronautical direction finding beacon, callsign "LYQ" on 529khz.
Nice catch.
