I have installed a Cobra 19DX IV in my 90 wrangler...it works fine until my electric fan kicks on then I get a ton of feedback. My antenna is grounded,I put three chokers on the power supply,tried running power and ground directly to battery and then power to fuse panel and ground to body. This is all new equipment and I really don't know much about troubleshooting CB issues. anyone have any advice on this?
