Did you know that if you either forgot your dryer sheet or left one in so long it quit working, this shows up on AM radio?

Taking clothes out of the dryer

I have never tried that cause I care about my appliances.... :

Are you going to be OK?
There is a scenario that might explain this. If a dryer sheet removes the static from the clothes and if it stops working, then static electricity might build up on the clothes, and when they are pulled apart, the static discharge might affect a nearby AM radio. Similar to pulling on a blanket or a sheet during a cold dry night. Can't say how I have tried the experiment though.
I was thinking something similar. Once the clothes are completely dry and the softener sheet is either spent or missing, you might get some static buildup that would be audible on a nearby a.m. radio. But I also think most of the time during the drying cycle, you wouldn't notice anything because the clothes would have some degree of wetness that would prevent the buildup of static.
My particular interference problem is my iPhone charger. If I have it too near an a.m. radio, I get a pulsing type of static interference.

He might mean it shows up as a show topic.

Ba da boom!
My particular interference problem is many of the local stations blocking/desensing my radio, in addition to the static-generating devices radiating at a level higher than what would be 180dB below historically lowest naturally-occurring noise levels (assuming you're trying to receive PSK31 or something with better efficiency, which no receiver I have is capable of decoding), measured at the exterior surface of the offending device with its cover removed.
Anyone care to explain how is it that I can go something like 20-30 miles farther (also away from saltwater) from some AM stations (toward a rural area out in the middle of nowhere), and the signal actually IMPROVES in quality? Shouldn't I expect a barely-readable signal 115 miles away, for example, to be undetectable at something like 135 miles or so?

Yeah, it's 7w.
I'm just east of the edge of 15, into the 8, barely, near San Diego. One station that seems to improve is right on/near the border of the maps near L.A. / Pasadena / Arcadia area. When I go some distance east from home, into the "4" area, the signal quality seems to improve. Yeah, the signal strength indication goes down, but the signal to noise ratio improves. At home, that station, 1110 KDIS, gives me an indication of 41 dBuV strength and 0 dB SNR on the Tecsun PL-380, but out in the sticks I get 10 dB SNR (although the indicated strength drops down to 15 dBuV). It can be heard at home, but it has the sound as if another station's carrier on a nearby channel is suppressing them, although I can't hear the offender's modulation that far detuned. It's cleaner in the rural area, although still somewhat noisy due to the weak signal.

Check the box for an FCC Part 15 certification. Submit wide-scope dBuV traces to the FCC. Wait ten years; be told they are a regulatory, and not an enforcement agency.
Or...
Have your neighbor complain that the dryer's antenna is an eyesore and unsafe and violates the covenants, and fine that dryer into submission.
Or...
Go with it and change to LPFM on the bottom of the dial and set yourself up in competition with the local college station or NPR outlet, you have legal precedent on your side.

Exactly. And if there was no dryer sheet, which sometimes happens, the clothes definitely stick together. They make a crackling noise when pulled apart, and as that's happening, the AM radio picks it up.K6JHU said:

It's called static electricity vchimp and yes, clothes in the dryer pick it up thanks to all of that tumbling, dryness, air movement and other factors. Pull the clothes apart and you get little static discharges. And that is picked up by an AM radio just the same as lightning is.
Basically, that's all there is to this subject.
Yes. I justwondered if anyone had experienced this type of phenomenon. People so rarely listen to AM radio. Then again, thereare so many annoying sources of interference.BRNout said:
