Just curious, does the big FLEX amp use the same two LDMOS devices
they’ve ever done
that before.

If I want more than my KPA500 puts out, I'm going back to tubes.

I'm in the ARRL CW contest this weekend and the KPA1500 has been working
fine. However, a few minutes ago I noticed I was getting about half the
output power on 20 meters that I typically get with around 30 watts drive
(about 600w vs 1200w). PA current is less than normal, around 30a.
