Re: Pi 400 and RF

Hello. I had similar issues and a couple of generic clamp-on ferrites fixed it for me. One on UTP ethernet cable, another on the 5Vdc power supply cable was all I needed. 73

Is anybody experiencing RF problems with the Raspberry Pi 400? I was
recently gifted a Pi400 and loaded the HamPi distribution. I don't have
RF problems with anything else in the shack, but when I transmit (so far
only on 20 and 40 meters) the Pi400 goes nuts. Stuff jumps around on the
screen, programs open and close and all matter of strange behavior. It's
like there are multiple mouses screaming around randomly clicking on
things. Nothing is connected to it, just the Pi400 with its stock mouse
and power supply hooked to a generic monitor. It was on a small table
several feet from the radio. There are four other computers in the shack
and a variety of other things that are not affected at all.

Thought appreciated.
