[Elecraft] [K3S] K3S High SWR Shutdown on FT8?

[MaverickNH]

That alarm turned out to be my USP - the sound was hard to track down as it's
on the floor. The USP is a CyberPower CP1500PFCLCD which is giving an
Overload alarm on typically the last TX of a QSO at 100W. The specs are
Output 1500VA 900W.

I'm curious why power consumption increases with each 15sec FT8 TX, when I
have a SWR 1:1 with a SG-235 antenna coupler at the base of my 43ft
Vertical. PA Temperature runs about 40-42C when the overload alarm goes off.
