For one station where they kept forgetting to reduce/increase power,
I bought 3 digital timers, the kind designed to turn on a table lamp
at a certain time. I made a pulse circuit out of a couple relays and
a cap, and connected the 2nd relay closures to the power
reduce/increase closure inputs. I had to set two of them once a
month, pre-sunrise happened at the same time all year, but power up
and power down were never a problem again.
You see Harold, everything old is new again...

35 years ago, when then class 4 stations were only allowed 250W at night,
I had a continual problem with announcers not changing power at the right
time. We had it as a program log entry, which they were constantly looking
at, but they still forgot. I put an Intermatic mechanical timer at the
transmitter site to force it to night power at the correct time. It worked
pretty well. No computer!
