Why when it gets late at night like after 9-10pm do the AM talk radio stations start to get staticy...?

Question

and go in and out of range? After midnight I can barely here anything! It drives me nuts!
How can I fix this?

I meant this hear :)

Answer 1

You should receive your local AM stations clearly at any time of day, unless you are listening to a very weak station. If you are listening to distant stations that "in & out" effect is caused by the fact that at night AM radio signals will bounce off the ionosphere and travel great distances. In the radio business it is referred to as "Skip". Clouds, air currents, and other phenomina interfere with the signal and causes the effect you mentioned. It is even more noticeable if you were to listen to Short Wave radio.

From your home in Las Vegas you should easily receive KFI (640) in Los Angeles, KOB (770) in Albuquerque, KLS (1160) in Salt Lake City, and KOB (850) in Denver relatively clearly at night. A more distant station like KGO (810) in San Francisco would probably give you an "in & out" signal.

This does not happen with FM stations because their signal is "line of sight", that is, you will only receive their signal if there is nothing obstructing a clear path from their transmitter to your radio. I hope this is what you needed to know.

There doesn't seem like too much that can be done about this. Apparently, during the day AM stations can operate during the day on the same frequency without interfering with each other, but once the sun goes down that's another story. At night the AM frequencies can travel farther.

So after midnight you're starting to pick up an another AM station on the same frequency or close to the same frequency.

Here is the problem

AM power stations are regulated by the FCC and during the daytime hours - may operate at full capacity

when the sun goes down - the AM range increases as the sun limits their effectiveness - and the FCC makes them lower their power - so as to not interfere with radio stations in other states - hence - MORE static and harder to pull in

on some nights in central Florida - I can pick up the South Carolina Station and other nights - el statico only

best of luck!

Answer 5

The stations reduce transmit power at night, there's fewer listeners and it saves money. Nothing you can do.
