Man, do I have e stories. LOL. When I use my GMRS radio while in my driveway, the garage door opener lights turn on. In my last Jeep, I had to move the antenna because when I keyed up, my dash would reboot, run self diag, and my windshield wipers would turn on.
I also have a HF radio and an amp that puts out about 1,100 watts. If I run it full-tilt, LED lights in my house that aren't even plugged in will actually light up. It trips my wireless surround sound, turning that on. And depending on the frequency, it makes my radio/alarm clock's radio turn on until I let the mic go.
RFI does some wild stuff.
