HiSo I am trying to get my old K1 back up and running. Two, 2 band modules,
80/40 and 20/15 and b1 on each was dead. No oscillator signal at pin 4 on P1,
b2 fine. Replaced X1 crystals on both boards because the boards had been in
storage and bounced around. No change until I tapped on K1
I am in search of a 2 band or 4 band filter board for a K1. Any help would be
appreciated, you may contact me by e-mail at aaherb...@hotmail.com.

Jeremy,
Yes, an RF probe would be useful to evaluate the health of the crystal
for 40 meters.
Since those crystals are reliable, I suspect that you have a problem
with the Pre-Mixer Bandpass Filter.
You need to have at least 200mV peak to peak signal (70 mV measured with
an RF Probe) to
Hello,
I recently finished the receiver portion of my K1 (40m/20m). I successfully
aligned the 20m filters, but on 40m there is very little noise, and the noise
does not change when there is an antenna connected. However, I have received
some very nice signals on 20m.
I have inspected the
Check to be sure that you have set the correct 30-meter band edge (10.0
or 10.1, depending on your chosen VFO range). See the manual's
instructions for setting the Bx parameters.
Some years ago I had a problem similar to your first one. It turned
out to be a defective pair of relay contacts on
I have a K1 with the 4 band filter board (40,30,20,15). I recently removed this
board and tested a two filter board (80,17) that had come with this radio. The
second board worked fine but the problem I have is that when I replaced the
original filter board and reconfigured the band settings,
I have completed soldering the components for the K1 2 band filter
board, but when I performed the resistance checks, there was a
problem.

I have a K1 in which I just swaped the 17M parts for 20M parts. Now the
filter board needs to be aligned. Question is how does one get around the
KAT to access the filter board?

Just remove the tuner board and install the jumper in the tuner connector,
do the alignment and reinstall the tuner

I bought both a 4-band and 2-band filter board for my K1. I built the 4-band
board for 40, 30, 20, and 15 meters.
I have parts to make the 2-band board either 80/17 or 80/15. I've also
considered the 160/80 option. That's not what's bothering me. Here's the

What about calibration?

I have obtained a K1 and have a couple of questions regarding the KFL1-4

I think that's the best and *only* practical approach. That's what I did
with my old two-band filter board after the the four-band board came out.

Hi Daniel:
Well, he MIGHT be able to come up with a filter to cover 80/60, but I'm not
certain about the signal inversion on that band... might not permit USB
reception... can't believe the FCC mandated USB in a (larger) band segment
which typically ALWAYS defaults to LSB, due to mixing

Ron,
The 4 band board will not work well with 80 meters (it becomes a '3 band
board' due to the low pass filter sharing), but may I suggest that you build
the 4 band board and then add a 2 band board with 80 meters as one band -
the other band can be 17 or 15 meters (the one that is missing
