This evening after dark I drove around and had my feelings badly hurt by the poor reception from my AM radio transmission which was being entirely swallowed by the entire universe of other babble. “This can’t be right!” I said, and began going through the FCC waste basket from a few years ago.
Way down deep in the waste-can I found a lost rule that had accidentally fallen off the edge of a typist’s desk and never got put in the Part 15 Rules that went to press. Here it is, at long last:
15.222 Nighttime operation in the band 525 – 1705kHz.
To compensate for pretty bad performance after dark other things can be tried just so the damn signal at least matches what you get in the daytime.
Don’t thank me. Just be glad the government puts their wastebaskets into internet databases.

The Good, The Bad, The Way It Goes
Ya..sometimes that mess at night gets pretty bad and even so bad enough it affects CC as well, sometimes severely.
All those power lines absorbing all that garbage through the air killing the 219 is just as bad if not worse, and it can be worse a lot more often than even when through the air garbage is not so bad.
There should be a contact number or online form over at the FCC website to let them know you found that long lost rule they forgot about from the initial act back in 34. 🙂

When I Was On AM
When I Was On AM on 670 KC in 2008 at sunset i had to sign off and stay off until sunrise or 9am the next day but when i moved to 1210 KC in 2009 the frequency was pretty quiet daytime and nighttime, in my locality… so when i made the move things were going good until the tioga sonic boom and the storms w/ landspouts came.

KSKY had to hurt you a bit on 670.
