[Elecraft] K1 Low power output on one band

[Michael Carter]

Hi Paul,

It does sound as though the slug-tuned inductors
on the 20 meter and 15 meter sections of the
Filter board need tweaking.  As you noted, one
must remove the KAT1 ATU board from the
Filter board to access those coils.  It is necessary
to jumper pins 2 and 10 of J2 on the Filter board
to route RF to the antenna connector.  Once you've
done that you can proceed with the alignment
as described in the manual.
