I have been doing some testing using WSJT-X, and other digital modes, with my
K3 an my Signalink USB.
Receive works pretty good with decodes on WSJT-X at –19 to an occasional decode
at –24.
On transmit using various digital software and modes, when I transmit at 5
watts the KAT500 has problems.
I tune up with 20 watts, all is fine, 1.0 swr. But then I transmit with
power at around 5 watts, in a digital transmission, the KAT500 starts a
tuning cycle, then ends in a fault condition. If I transmit with the power
above about 10 watts, clear up to 100, everything works perfect?

Hi Emory,
The KAT500 design is optimized for 10W through 1000 W operation, with better
tuning above 20W. It is not designed as a QRP tuner. It can be used at 5W
levels, thought we do not guarantee this, if it is pre-tuned first at higher
power (20 W +) on each freq and then run in manual

The reason the KAT500 is misbehaving is that it is a high power antenna
tuner. Last I looked, 10W was the minimum power for tuning. That's why
Gary advised you to take it out of Auto mode once you've trained it with
higher power and stored settings.
