1550 AM - KUAZ - Tucson, AZ Goes Dark At Dark

KUAZ is one of the few AM stations that completely shuts down at dusk. Here are the last couple minutes of its broadcast on Wednesday, June 9, 2021. Listen for the carrier dropout.

Yeah, WTF is up with that!? Are they required to go off the air at sunset? I live too far away to get the FM station, so before I could get a smartphone I had to rely on the 1550AM broadcasts.

Yes, they are required to go off the air to protect other stations on the same frequency.

@@FandCCD Ah! Thanks for the explainations - that's always perplexed me!
