Whine on CB/Ham radio
I have a 2004 F-150 & trying to install a CB radio.
I get whine that changes with accelaration. It comes & goes
& sometimes just keying the mic once it will go away. It does come back & seems to return when going over small bumps (but not large ones).
It varies how loud it is...sometimes it's fairly low (but still annoying)
but sometimes it's loud as heck & thats all I can hear.
I've tried 3 different radios, 2 antennas & shielded the power wire. Yesterday I couldn't get rid of it at all. The radio is wired directly to the battery. I can't see any loose connections & had the dealer check all the ground straps etc.
Once it ran great for about 3 days but always seems to return without changing anything. The dealer found a loose battery terminal & fixed it & it helped with some ignition noise but the whine returned after about 6 miles of driving.
The stereo in the truck is fine...no noise or even interference from the CB so what could it be? The dealer is willing to work with me on it...was wondering if there's anything I could give them a heads up on...any ideas? Feel free to ask me any question...I will respond...really wanna get this fixed!
