Charging system question
#16
Probably a good idea to forget a CB radio and just go ahead and get a ham license. Even as a technician (the lowest level below general and extra) your allowed up to 1500 W PEP from your transmitter. True, you'd never push that much out with a mobile radio. But you could get a 10/12m radio for about the same price as a CB (11m). Plus they even make radios that are "opened up" on CB frequencies so you can operate there too.

Hey mr tjc, I got my radio wired directly to the battery and when the truck is on I'm getting an rf signal and interference along with rpm whine... Could it be the ground?

Yes. You want to make sure your radio goes directly to the + and - terminals of your battery. Make sure you put a fuse near the + battery terminal (at a minimum).
You can also get a Mix 31 RF choke and install it either on the RF coax right before the antenna or on the + DCV wire going to the back of the radio.
There will also be a single point grounding lug on the back of the radio. Run a wire from that to a bolt going through your seat into the floor pan. Burnish the leg of the seat with sandpaper or a wire wheel and use a star washer between the seat leg and ground wire.

The only way to completely eliminate interference from your alternator is to make sure it's not spinning. I installed a switch in the 12 VDC power wire to my ham radio in my Oldsmobile so I can run it off the car battery or an auxiliary deep-cycle battery I installed in the trunk.
The glow plugs interfere with your CB because the secondary side of the GP relay is high current. You can add RF chokes that will at least help.
