I'm learning about a new KPA500/KAT500 installed with my K3S. When I have the
K3S power knob set, in this case, to show 420-440W peak-hold as read on the
KPA500 LED screen, I see the KPA500 SWR showing 1-3 LEDs lit (it may stay at
1 LED or climb from 1 to 3 LEDs over 15sec TX, always below 1.5), the KAT500
with SWR 1.2 LED lit, and P3TXMON indicating SWR 1.00 (it might start at
1.15 and settle back to 1.00 over 15sec TX). But PEP on the P3TXMON can
range from 10-15W up to ~400W on successive 15sec periods of TX using WSJT-X
FT8 (going for very distant CQs). Adjusting the K3S power knob down may
bring P3TXMON displayed power up if its 10-15W. If the P3TXMON shows 200W
adjusting the K3S power knob up may bring the P3TXMON power shown down.

Is that how it's supposed to work? 

I have a P3TXMON 2000W 1.8-54MHz unit installed on my feedline at the rig as
follows:  KAT500 to Common Mode Choke to P3TXMON to Bias-T to SG-235 remote
ATU at antenna base to 43ft Vertical antenna, with some Lightning GDTs
between at antenna base and home feedline entrance. My tuning practice is to
change Frequency, turn KAT500 to BYP, tune the remote ATU, then set KAT500
to AUTO and let it adjust on 1st TX.
