[TVARC] Batavia FT8 Contest - 2020 - SOAB-HP

[Rich Erlichman]

Pete and Ed,

I too, see the overshoot on the LEDs when the amp initially keys up. I have
a feeling it is a peak reading, and then quickly settles down to the average
wattage output.
I found the ARRL review video and it shows the exact same response when
keyed. https://www.youtube.com/watch?v=V-PTEKc3fnI
And what do you mean now that I settled down???

73, Rich, ND4G

Pete,

I've observed the same behavior on occasion.  My thought is it's from a
momentary overshoot by the exciter causing an overdrive situation.  The
K3 remembers the drive setting for each band and mode.  I've had it show
500-530W on 40 CW without any ill effects.  On modes like FT8 and RTTY
where the DC is higher, the amp backs off 10-20W from peak when it gets
hot while running.  

Solid state is nice for efficiency and weight but give me an Eimac tube
and a BIG power supply for plenty of head room.

73 de Ed
