Sorry for the delayed response -- been out of the loop for awhile...

No doubt true -- but if I shorten one leg to balance it on one band, 
will it still be unbalanced on other bands? Possibly a moot point in any 
event, as my climbing days are pretty much over.

Sorry -- not arbitrarily rejected. Usually other reasons --  like being 
too cheap <grin> to purchase two 4:1 baluns, not practical to move the 
rig outside, climbing days are over, etc. Believe me, even though I am 
not able to implement all of the suggestions, the comments of you and 
others ARE appreciated!

According to a recent conversation with TT tech support, early vintage 
Omni VI's like mine were shipped without ferrite beads on the mic jack 
leads, and even though TT graciously sent me the beads, they seemed to 
think that it still would not cure the problem. Short of moving the 
antenna (not possible), I may be fighting an un-winnable battle. Thus my 
hinting around to the group to see if anyone else here had experienced 
the same problem with their Omni VI (and had a fix) -- or knew of a 
relatively bullet-proof Yaecomwood or newer model TT.

You are correct, it is an FT-107, probably near the vintage of the TR-7 
(which worked). A newer radio does not appear to be available; had a 
local friend with an Icom 745 -- but when I called him, it turns out he 
traded it off and is currently  without an HF rig.

As the antenna is not moveable, maybe the non-elegant solution is to see 
if anyone knows of a Yaecomwood or newer TT that is NOT susceptible to 
RFI. Unfortunately, this does not appear to be a parameter that is 
covered in the QST reviews.
