SWR will not make a difference in the whine and as a matter of fact it may
worsen it if you went down to 1.5 to 1. Same as having a good ground will
make on difference in the whine. You need to have those fixed if you plan on
transmitting to save the finals. Try re-routing the coax and using ferrite
chokes on the cables coming from the alternator. I do believe that the 29
has a NB or ANL switch on it. try using them and see if that makes a
difference.

I drive a 9900 International. I am getting a loud whine in the CB speaker,
but not in the radio speakers, even though they share the dual antennas.
The
whine increases and decreases with the rpms of the motor. After
disconnecting the coax from the CB transceiver the whine is gone. Does
this
mean the coax or antennas are definitely the problem? ... or are they just
picking up on a problem with the alternator? The coax will be extremely
hard
to replace, maybe impossible since this is a company truck. The alternator
would probably be easier to repair.

Any help to eliminate or even reduce the whine would be greatly
appreciated.
