I turned on my car radio today and when I switched to AM nothing was there! That is until I turned the volume way up, so loud that when I switched back to FM it hurt my ears. Every AM station was like this. What would cause this? I looked at KFI's Twitter and found no mention of the issue. Maybe it's just out in Ventura County? Or my radio could be broken. ¯\_(ツ)_/¯

AM radio literally quieter in Simi Valley
- Thread starter SimiRadioListener26
- Start date
Possibly the solar storm which began early on Monday? There was a discussion on the DX & Recpetion board here of unusual reception patterns.
The only true local signal is 670, the Farsi language station. Is it also weak?
Next closest is 1260, but it is some distance away and its pattern does not favor your direction.
Radio's busted.
Everything's back to normal now.
Interesting thing about 670… I remember traveling on I-80 between Reno and Winnemucca, near Lovelock in 1980 and hearing both KBOI 670 and KNBR 680 during the They were two weak to really interfere with each other, but strong enough to listen to.
680 & 670 don't interfere with each other.
670 Las Vegas causes most of the interference to KBOI.

Yeah and back then the Vegas 670 probably wasn’t on the air yet.
On the last two Subaru cars I've owned, and a Mazda some years ago, AM reception would get quiet when I was driving close to an active AM transmitter site. Something to do with the Mitsubishi-designed car radios, is what a mechanic explained when I brought it up.
Now from what you said, it doesn't sound as if you're near any transmitter sites. Unless there's one hiding that you can't see from the highway.
I live two blocks from an AM transmitter site of a station at a low dial position (630) and it messes up reception on the dial on all my radios, and even somehow brings in another local market station (570) that hijacks the frequency of a hi powered station from 100 miles away (one I actually would rather listen to - on AM 690) until I get a mile or so away. Or until they sign off at sundown and use a different transmitter site.
Just bringing that up in case anyone else has such an issue and it's not a freak cosmic event that's causing it!

On some car radios the AGC circuits will desensitize the receiver when close to a transmitter site to prevent overload. Can happen on both AM and FM.
