The AMs be bleeding!

[dxstuboy]

I know, I probably complain a lot about engineering problems but during today's snow storm, I decided to try to see if I could hear anything other than locals on the AM band.

What I noticed is an enormous amount of bleed coming from a lot of the local stations.

The bad stations in particular are KMRI and KBJA, who splatter all over the dial. There are a few frequencies in particular that bleed onto one frequency, 780 being a bad one. 1700, and 530 were also affected. I know there are two highway advisory radio stations on 530, but I could hear neither due to the bleeds. I think the other higher power ones are doing it too, there literally was too much to know who.

I was on I-15 at about 4500 south in Salt Lake, hearing these. Could it just be my radio, location, or is it something else?

Anywhere outside of Salt Lake City, this usually isn't a problem.

One possibility would be front end overload. KMRI is about 7-8 miles from there. KBJA is closer, but still 3-4 miles away. What IS right there is KJQS 1230, and I would suspect that was creating some havoc in your radio with other stations. The science of how that math works is a bit beyond me, but I would guess that's the cause. I'm attaching a picture from Google Maps of the area that shows where the transmitter is.

A lot of it may be due to inter-modulation in wet power lines, especially the ones on poles that have "donated" their copper ground lines to the economic situation.

Could you explain that a bit more? When I drive around Seattle, AM radio can be a pain in the neck thanks to our "trolley" wires all over along with electric wires buried below arterials, etc.
