[TenTec] RF Feedback

[Barry N1EU]

Sorry for missing the beginning of this thread, but I just read it.

Long time thread readers may remember my difficulty in solving a distorted 
(rf) ssb audio problem on 17/12 meters with my Omni 6 two years ago.  I 
tried everything.  I cornered the market in ferrite; I enhanced the rf 
ground to the radio, etc.  Only thing that seemed to help was putting my 238 
tuner between the Omni 6 and Centurion.  Changing the interconnect length 
also modified the symptoms.  These were misleading clues - the problem was 
really in the internal ground wiring of the Omni 6 but I didn't know it yet.

Then after six months of beating my head against the wall, I finally spoke 
with a different person at the factory, who recognized it quickly.  Earlier 
Omni 6's need an update that I believe separates the grounds in a couple of 
circuits.  I don't profess to know much more than that.  But I sent the rig 
to the factory and it came back with no trace of the formerly severe 
problems.

Don't know if this help.

GL/73,
Barry  N1EU
