[ICOM] Icom 706 MK IIG distortion

[bbrewer]

John,

I had a similar problem with feedback into my stereo speakers. The first
thing that helped a little was to put the screw in the remote cable
connector. My big problem was using 2 different sources of power for the
radio and the antenna. My radio is directly connected to the battery,
but as a "temporary" setup, I connected the screwdriver to the cigarette
lighter. I had so much feed back that 20 meters was virtually useless. I
finally made my permanent antenna connection direct to the battery and
my problem was solved. I don't understand what was happening, but I
can't argue with success.
Don't know if there is anything here to help you, but good luck and
happy hunting.

Need benefit of your experience with Ic706 MK IIG.

I have an Icom 706 MKIIG driving a Metron amplifier in
my mobile. I have one setup in my motorhome and the
audio and signal are clean. I have another identical
setup in my Saturn Station Wagon.The rigs are
identical even down to both using the DK3 screwdriver
antenna.

The rig in the Saturn has "fuzzy" audio on transmit. I
suspect RF getting back into the 706 in some manner. I
have only tried the rig on 40 meters since installing
it in the Saturn, and that is where I am experiencing
the problem.I have had the same mobile rig in several
vehicles and the only time I had a problem before this
was when operating with the separation kit in a Nissan
Pickup truck. The digital readout would go in and out
when transmitting.I placed a ferrite bead on the
separation cable right at the remoted front panel and
the problem disappeared. I hear a faint feedback in
the external speaker I am using in the Saturn when i
am transmitting .

If you have had a similar problem with the Icom 706 MK
IIG, I would appreciate the benefit of your results
and what you did to clear the problem . Would also
like to determine the cause of the problem. Thanks for
reading and lending me the benefit of your experience.
