I don't THINK it's a cable. no amount of beating, poking, or flexing seems
to make any difference.

 

I've thought about the notch caps.  I do have a couple of spares. maybe I'll
try to swap them in.

 

The question is. WHICH TWO?  I've swapped TX and RX sides of the duplexers
already with no effect.  You'd think that the notch caps on the RX side
would be the ones that'd cause the most grief, but I can see how the others
would too.  Either way, I'd have expected to see some difference when I
swapped TX and RX sides.

 

I have a strange feeling that it's arching around the fingerstock.  The
inner tuning tubes showed definite signs of wear, but I THOUGHT the
fingerstock was making good contact.  Is there any 'approved' conductive
lubricant for that area?

Sounds like maybe a bad notch cap or a bad harness cable. At first I thought

maybe a transmitter spur, but you've now ruled that out. Neither may show up

on your HP, but under real power it could.

I neglected to mention in the first post, but I also put the crystals into a
2nd repeater we have and had the same problem.

I may have to try tuning the cans on our spare 6.85 machine.

David,

Not sure what you're asking, but if you're asking about spurs, she's a clean
as a whistle. VSWR is fine as well.
