Thanks for the reply. I had a lot of noise issues. After reinstalling the
damn thing about 10 times over a period of 5 days, I have now found that
the best power source (with least rf interference) is the head beam power
lead before it goes into the head lamp switch. I have put the negative on
the firewall inside the dash. Additionally, grounded the chassis of the
radio to the firewall as well (separately). Now the noise level is
minimal. Although, there is still some alternator whining. I have got the
filters, which I will be putting on this weekend. It seems to be working a
lot better now. It was a big trial and error. On the plus side, I can now
take the dashboard apart in less than five minutes!

As for antenna location, anywhere front of the driver seat caused a lot of
problems. I had now placed it just above the rear left brake light. My
logic was this way it was farthest from the AM/FM radio antenna. It seems
to be working. I am going to put a grounding strap on the antenna mount,
just waiting for it to arrive in the mail.

I missed part of the thread. Are you saying that "the best power source
(with least rf interference) is the head beam power lead..." has less
noise than running straight to the battery?? Why are you not running
the power lead directly to the battery?

Well, thats what I did the first time I installed it. There was so much
noise and interference that I could hardly make out anything. I then tried
different sources till I found the head beam power cable. Now I have no
interference from the turn signals, horn, lights, fuel pump or wiper motor.
I do have very slight alternator whine, but its acceptable and will go away
with the filter I am fixing tomorrow.

I know hooking up this way is not advised. But this is the only way CB has
worked in my RHD export TJ. Our computer unit, battery and distribution
panels etc.. are all on the left hand side (either side of the firewall).
My power cable is now on the right side towards the steering column inside
the cab.

I am thinking of it as another Jeep thing.

:) My first thought is that you routed your power leads past some
offensive piece of electronics. One way to test it would be to drape
your power lead from the back of the radio, out the door, onto the
garage floor and around front to the battery, away from all Jeep
electronics. If you still have interference, I'd be surprised. That way
you can determine if it is just a cable routing issue, or not. Do the
same with the anntenna coax. Keep us posted. Sorry for being so late in
the game, here.
