A friend has a problem with EMI. Can anyone give him ideas to help troubleshoot?
It's an aircraft avionics issue in a glider cockpit. Everything is powered by battery.
He's not on Fedi/Mastodon.
His description is below.
Thanks in advance!
====================
I have 2 electrical devices that are causing interference with any nearby radio. Initially, I thought it was just my radio but it's any radio. So, I am no longer looking for an issue with my radio or antenna.
However, I did find a spectrum analyzer that can also generate a frequency simulating EMI (I think)
For testing purposes, I supplied each device with a separate battery.
I tried using foil around the 12v USB and variometer. Again, with no change. I also tried foil around the radio.
Not the best Faraday cage.
Usually, I get some sort of change. But not in this case
