[TowerTalk] SWR Problem with Tri-Bander

[Jim Jarvis]

If it were balun connections, why would
it manifest only on 15 meters?

If it were the 15m traps, or one of them on the DE,
why wouldn't the current on 20 also heat it, causing
a shift there?  Still, I'm betting it's something 
askew in one of the 15m traps.  

Can you run it near ground, so you can put your hand
on the traps, after running key down for a bit?  
power off, of course.   Something's heating up, for sure.
You should be able to feel it.
