After 5 years of perfect operation, now a very strange issue
Bypass SWR 3 or 4:1
KAT500 tunes to 1.3:1
Switch amp to operate, operating SBB on first voice KAT500 goes full scale

Never had a issue before, antenna is g5rv
Any ideas appreciated.

Jack, I had a similar thing happen
I accidently sent 200 watts pep to the KPA500 input however it did not fault
on high input power.
Thought I would check here first before calling Elecraft

Can someone explain the VFWD and VRFL readings in the bottom right of
screen?
When I put out a 15w tune signal, VFWD reads 225 and VRFL reads 2 to 3
Just trying to make sense of the readings

Is there a Auto Power Off setting in the K3?
I cannot find this in the manual so it's probably not available but thought
I would ask the brain trust.

I am trying to tune a G5Rv on 4.7xx (MARS freq) best I can get with the
KAT500 is 2.65 swr, which means cannot use the KPA500.
Using the K3 barefoot with ATU it tunes to 1.0 swr
Why is there such a big difference in performance?

Trying to tune a G5RV on 4.7xx mhz (MARS Freq.) best it will do is SWR 2.65,
which means I cannot use the amp.
K3 barefoot will tune SWR to 1.0

Is there any way to assign a different drive power setting to the K3 when a
different antenna is selected on the KAT500?

I leave the KAT500 on 24/7, several years of perfect operation.
Today I sent the usual 15 watts tune carrier on 75 meters the tuner started
cycling
all lights on and off. Turned the tune carrier off but the tuner continued
to cycle.
Tuner will only turn off by removing power. Plug power back in
Thought I would report the solution, tried a different power supply to the
tuner.that was it.

I leave the KAT5
I just read in the KPA500 manual not to exceed 100W in StandBy mode
Woops.I sometimes run 150W to 200W digital when connecting to Winlink with
KPA500 in StandBy
I won't do it again will limit to 100W However, curious if anyone know why
the limitation to 100 watts?
