[Elecraft] K3/KPA500/KAT500 SWR problem

[Jeffrey Otterson]

I reported this problem to support back in February, and though my question
was responded to, it was never really answered -- I've been living with the
problem since..,  I'm sure support can look at the case, it was around
February 7 of this year.

Before I switched to KPA500/KAT500, I was running 12-1400 watts PEP from a
SB-220 through a Drake MN-2700 tuner, with never an issue, so I don't think
the problem is arcing connectors, balun, coax, antennas.  Also the raw VSWR
on my 75M antenna is about 2:1, maybe a bit better. (The K3 says 2:1, the
LP-100A, 1.98:1), so I don't think the problem is brought on by excessive
SWR...
