Well I have learned a tremendous amount about whine in a CB in the last
week. I stopped by a shop today to purchase a capacitor that I was going to
place on the alternator and the tech said he could fix the problem for
twenty dollars. I watched him open the unit, desolder a capacitor and
resolder a larger one in its place, he then shorted a couple of connections,
probably tweaking the unit. I figure he was doing the same thing I was going
to do but he did it inside the unit. I can just barely hear the whine ...
well worth twenty dollars.


He didn't fix the problem, he just covered it up for a fee. It would
cost you much less than twenty dollars to mount the radio properly,
which would eliminate the whine (as well as other noises that the
tech's 'fix' won't fix, as you will soon find out) -and- improve your
antenna's SWR.


I want to thank everyone for taking time to help me ... I did learn a lot
and I might put it to use when I have more time.


Better save these posts. You will need them in the future. You should
also do a radio check to see if your audio is clipping -- the tech's
'tweak' may have been to bypass your limiter, which will cause your
signal to splatter onto other channels.

Yes , I have already noticed alot of background noise where there was none
before.

I have already saved all of these post. When I have more time I will apply
what I have learned. You will probably hear from me again

Hello Frank

Can you recommend a book or two that will teach me about CB
fundamentals, repairing and tweaking?

I have an little electronic background and even own an oscilloscope. I
think that if I learn the workings of a CB from the ground up it will be
easier for me to troubleshoot them. The first book should be very basic so I
can get the fundamentals down before diving off into the deep end.

Thanks

"The Radio Amateur's Handbook" by the ARRL is exactly what you are
looking for. You can usually find a copy at your local public library,
or pick one up on ebay for just a few bucks. Just about any edition
printed in the last 20-30 years will be fine. I do -NOT- recommend any
of these 'CB-tweak-n-mod' books or CDs -- not only because most of the
mods are illegal, but because most of the information is gathered from
wannabe techs and power-junkies that have little experience and even
less formal education in electronics. Learn electronics the right way
and you won't have to unlearn a whole bunch of CB-voodoo later on.
