You should hear relay clicks because they are switching trimming
capacitors in and out when you switch between 10m and 12m. Out of
curiosity, could it be a faulty relay somewhere in the band pass
filter area? If it cannot connect both trimming capacitors to the
filter when you switch to 12m it migh

Andy,
Are you peaking the inductors for 10 meters before you peak the trimmers
on 12 meters? That is the required order for the bandpass filters - of
the band pairs, the inductors must be peaked first and then the capacitors.
On your 10 meter problem, check all the components in the Low Pass
Hello all,
First up I'd like to say what a superb kit the K2 is, I've really enjoyed the
time spent quietly soldering away and the instructions are first class with
some great finishing touches (all the resistors in sequence on a custom strip -
what will they think of next!). It's a shame it's

Guido,
I would first look at the bandpass filter - on 20 meters, capacitors C28
and C29 and trimmers C21 and C23. The symptoms sound like a bad solder
connection.
For the 17 meter problem, check trimmer capacitors C32 and C34. If that
does not produce results, then check the VFO frequency whe
Dear K2 specialists,
I recently finished my K2 with (more or less) no problems. Everything is
fine, expect the transmitter alignment for 17m and 20m. Here are the
symptoms
found while doing the alignment with 2W output in tune mode:
1. On 20m, the output power is rapidly changing between 0.1 an
Still trying to align the filters on my K2, but was getting no
indication the Frequency Counter Probe Assembly was working. So I
ordered a new and and still nothing (when touching the side of C22, when
doing Cal Fctr or Cal Fil). Removed the DSP filter, AF filter and
Control Board. Cleaned a
Still trying to adjust my SSB Filters. First it was INFO 230. I plugged
in the probe and it worked the first attempt. Then when I the next day
to continue git'r done I keep getting INFO 230 on CAL FIL, CAL FCTR, and
it will not read anything touching the side of C22. I took the probe
