Electronics & Radio - Reducing the noise from my camper's LED lights.
That's a great video, and helpful. Unfortunately it doesn't solve the real problem: manufacturers using cleap, chinese made parts that do not meet FCC requirements.... even in campers that cost a LOT of money. My own little trailer is very quiet, but when we take it to a crowded camp ground you can barely use the radio. The QRM from all of the other campers drowns out virtually all of the incoming signals. It sounds like some sort of Russian Jamming!
I also had a very noisy AC/DC converter which I replaced with an Alinco 30 AMP supply. Thanks for your video.
I too was plagued with noise from the LED lights. I replaced all the fixtures using fixtures that would take an 1141 LED...
Noise is now gone ! next stop is to do as Ron did, change the AC/D converter.
I've not noticed LED light problems in my R-Pod trailer but had some noise from the AC/DC converter also. I replaced the entire board with one from another manufacturer that was made to fit and it's much better on noise. The original converter developed a charging problem just out of warranty and was the main reason for the replacement. I am something of a fair-weather camper so most of my operating is outside the trailer and the noise seems to vanish rather quickly as you move away from the converter.
You need to realize that FCC rules do not limit RF emissions to zero nV. A device can radiate withing FCC limits and still mute your radio if you're close enough.

This should still be on the books, just applies to 700 Mhz. band- an example that the FCC does sometimes take action.
I go to Quartzsite Arizona most every year and as soon as it gets dark everybody turns their LEDs on. 20 over 9 noise
Then after they go to sleep it's very quiet.
But at Sunrise their solar controllers kick on and everybody turns their inverter generators on and their LED lights again.
20 over 9 noise.
It used to be extremely quiet in the desert!
My noise was my computer,,its full of LEDs
Great video and very helpful!
