55KRC not powering down at night

They're also not broadcasting in HD. An engineer at Clear Channel told me they were having transmitter problems. I remember WSAI not powering down for a few weeks last year. I was down vacationing in Red River Gorge, which is about 45 miles east of Lexington and remember WSAI coming in clear as a bell. Apparently, according to the Clear Channel engineer, WSAI is having grounding issues, which is part of the reason why their night signal sucks so bad. I wonder why they don't fix these things...
 
I'm aware of the problems with WSAI had. 55KRC must be having problems now because they were on their nighttime pattern one day last week as I could barely hear them. CC must have cut the engineering staff and budget again.
 
The engineering staff might have been a little busy with fireworks prep, and I've never heard HD on 55. I'd like to hear it, but I don't think it's installed.
 
WSAI was probably on night pattern while you were at Red River Gorge. They throw a nice nighttime signal over Southeastern Kentucky. I used to listen to them while traveling the Mountain Parkway at night when they did oldies back in the late 80's.

Back to double nickel, I was in Cincinnati over the weekend and noticed 540 and 560 was quiet and wondered why KRC was the odd CC station out of HD.

In my spinning the dial, I've never heard hiss on 540 or 560...if they ever had HD on WKRC, it's news to me.
 
Forgive my ignorance, but I always thought that AM stations powered UP during the nighttime hours. Is it the opposite? Why?

AM signals carry much further at night due to ionospheric (atmospheric) conditions. Thus a sunset powerdown.

And that's why epickles always thought AMs powered up at night- because they carry further at night. But they do that because of nighttime skywave, not because of additional power.

But not all AMs power down at night, that's just the case when it's necessary to protect from interference.

Sometimes it's a pretty drastic change. AM-680 in Charleston, WV used to be 50,000 watts day, and 250 watts at night. They've since moved that one and dropped to 10 K day / 221 watts night.

WHIO in Dayton is 5000 watts day and night, but directional at night, with the major lobe going north.
