I think the evening broadcast on 5085 tends to be irregular. I don't tune in often enough to know if there's a pattern, but it's definitely not on every evening at the same time.
I agree that something is up but likewise, no pattern that I have discerned.
They used to be very reliable when broadcasting a full show on weeknights a few months back. When I could not receive them the previous night I went to the web site and I could access the transmitter audio feed. That made me think the transmitter was still up but propagation was poor.
However, last night at 20:20 PST they abruptly stopped broadcasting in the middle of a song. Normally they drop at the top of the hour while playing a vocal of the Star Spangled Banner.
