[ICOM] IC-706MKIIG Issue

[KENT HUFFORD]

If the 706 had been that bad, they would not have sold 10s of thousands, and
the used price would not be as high as it is. 

If you have the 706 head on the long remote cable. Make sure you have the
little grounding screw connecting the cable to the base. That is a major
issue. 

Of course, check your power cable connection to the battery and the rf
cable/choke to the antenna(s).

I have the above radio that is having a weird issue.  It's had this issue
since it was new.

It appears to me that the radio is overly sensitive, both on HF and VHF.  I
bought the rig for mobile use but, due to this problem, it is unusable.  I
did the required stuff to the vehicle to reduce vehicle noise but soon found
that the vehicle wasn't the problem.  It's the radio.

When on HF, I get a constant S9 to to +20 noise level.  This occurs on all
HF bands.

When on VHF, particularly in an urban area, I have to have the squelch so
tight to avoid noise I cancel out most all signals.  The interesting thing
about this one is that on the commercial frequencies I monitor, I can back
the squelch almost all the way off with no noise showing up.  Every one of
the amateur frequencies, however, requires the squelch to be nearly fully
closed.  When I pass a bus or a recent model car, I get a quick splash of
noise as the vehicle passes unless I have the squelch very tight.

This issue had made the radio virtually unusable on the amateur frequencies.
I need to know if this is a common problem with the 706 and if anyone else
has experienced it.  Also, is there a fix for it?
