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.
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.
Looks like the problem was the simplest -- I just wasn't in transmit. Sheesh.
But better late than never, I suppose. Thanks again for your time, Don ...

Don,
The rig was in 'TUN' mode as according to the instructions, but I wasn't
actually keying down. Perhaps I missed that?
I checked out T1 but I'll triple check it this evening, and I'll also test
the diodes with my DMM since I'm certain of their orientation on the board.

Mark,
You did try the measurement during transmit did you not? It will be
zero volts when there is no power going through the wattmeter section of
the tuner.
Check the orientation of the diodes, and check T1 for correct
connections and good tinning of the leads - if you cannot see a bit of

Nothing is drilled or tapped in the heatsink or chassis! It is truly a "kit" of

Hello, Fellow Elecrafters:
I've completed and installed a KAT1 ATU in my K1-4, s/n 1453. I'm surprised
and pleased that in addition to effectively tuning the antenna & coax for
lowest SWR, the ATU acts as a "preselector" and improves the gain of the
receiver
slightly. All 4 band seem just a
