Randy,
Did the KAT1 wattmeter balance (null) and power and SWR calibrations
proceed without incident?
The voltage obtained during the nulling procedure should have been in
the low millivolt range. If it was not, the problem may be in the
wattmeter portion of the KAT1. Check T1 very closely. It must be wound
in the direction indicated in the manual diagram, and the leads must be
well stripped and tinned.

I'm hoping someone here might have had a similar issue, and save me some
time.
I recently installed a KAT1 into my K1-4. I have 40, 30, 20, and 15 meters
installed in the K1.
Symptoms: low output (0.1w) on 40 meters and 30 meters. KAT1 will not
match to 50 ohm dummy load on 40 meters.
I have cycled through the ATU menu, checking the SWR reading on each band,
for L0-4 and C0-5.I'll post the results in a separate email. The
relays are clicking on each band change, and for each L and C change. The
pattern wasn't clear to me; does this point me to C5?
The unit was working properly after KAT1 installation. I.e., the problem is
new.
I've reheated the KAT1 toroid leads, thinking I might have a cold joint. no
joy.
