Michael,
C13 is the Transmit Offset capacitor adjustment. It is quite possible
that there was a bit of oxidation between the rotor and the fixed plate
which was cleared by rotating the trimmer.

Well it is finally fixed. When I went to listen to the signal on my K3 I
noticed the frequency was off around 500 Hz or so. Tried to adjust the
sidetone pitch and nothing happened - test mode audio was weak and frequency
would not change with C13.
I moved C13 back and forth a little and
Michael,
One possibility is a bad relay or a relay mounted backwards or a relay
with a poorly soldered connection.
You cannot reliably check the inductor relays without removing one lead
of the inductors. Do that first.
Then in menu ATU CLP you should have continuity through all the inductor
Still have not figured out what's wrong with my newly built K1 w/ ATU.
For some reason everything is fine on the 40 M band but once I switch to 20
M the power output
drops way down. On the low part of the band the power output is much higher
but still too low.
I went thru all the C and L
Michael,
Did you change the jumper next to the BNC jack when you installed the
KAT1? If you failed to do that, the K1 would show a low power even
though it was actually developing full power output.
Make sure the ATU menu is set to CAL P.
If you are measuring power output with an external
I just built a new K1 and had some problems with the output power. To make
a long story short I
ended up having to lower the values of R5 and R11... This brought the
power levels up on
the 40 M band from 1.5 to 6.5 Watts and on the 20 M band from 0.5 to 5.5
Watts.
Figured all was well
