[OKDXA] KT-34A

[Kim Elmore]

On top of the power line QRN...

I recently noticed that my KT-34A has a significant mismatch on 15 m: 
about 3:1. A week ago, I didn't have this problem. It still has F/B 
and seems to otherwise work OK. Anyone out there with any ideas as to 
what might have changed? I was hoping for a windy day so that I could 
check for loose hardware but, of course, we have a calm day. I don't 
see any changes when I rotate it, but I have to wonder of all the ice 
and wind has finally done it in. Note that it still seems perfectly 
fine on 20 m and 10 m, something I find odd because the 15 m traps 
have to be OK for that to be the case. The mismatch appears to be 
independent of frequency.

Any ideas as to what might have changed?
