KCJJ AM 1630 Iowa City IA "The Mighty 1630" 10kw daytime blasting in here to Michigan at 1530Z on the car radio
with the "Rock and Roll Oldies Show". Huge signal 2 1/2 hrs past our sunrise at a distance of 450 mi.

Can you get them say mid day?

Got them all day today.

What a difference a day makes... KCJJ nowhere to be heard on 1630 late this morning,
nothing but static... strange. ???

It'd be interesting to compare ground conductivity at tx and rx sites, with respect towards rainfall or lack of. There's a bcaster here that most days is over 80dBm steady but sometimes falls drastically. I feel this may be ground conductivity related as when the sigs low, we've gone without rain for a period.

Josh,
You may be on to something here... some places around here got nearly 3" of rain over the weekend.
Did some checking, Iowa City got at least 3/4" rainfall and places between here and Iowa City all got
lots of rain. Looks like your ground conductivity idea is accurate.

In Omaha and surrounding area the ground conductivity is some of the best in the US, and I noted that ambc sigs were very stable as far as daytime sigs went. Moved to Indiana and here the local sigs are all over the place, sometimes even within the day.

look at that crap, went from a glorious 30 to a lousy 8

Ground conductivity in my part of the state is excellent.
However, as you move west the soil becomes sandy and the ground
conductivity sucks.
