Hi Don & Phil,

Hamlib3 version in WSJT-X do not seem to work properly. What I did was

I strongly recommend that you use PTT via CAT command for digital modes

If WSJT-X is not correctly communicating that command to the K2, look to

My best guess is that something has happened in the 15/17 meter bandpass

First - There is no association of the voltmeter probe and the frequency
counter - they use different headers and different circuits.
Now for your voltmeter problem - do you have the jumper on the 3 pin header
at the top of the Control Board? In one position, it will display the

Well, I have a problem with my K2, but don't know if it is worth

I'm having a slight problem aligning the I.F. amplifier.
The instructions indicate that the 7000 kHz signal will yield best signal
strength and lowest noise at about 1 to 1.5 turns below the top of the can.
However, the best 7000 khz signal
Michael,
Likely not a problem at all - it sounds like things are within the realm of
normalcy.
The peak on L34 is VERY broad - and that usually means that it is not
super-critical. The proper setting is for the best signal to noise ratio,
and that can vary from the actual peak. For the time
Last night, while driving home from work, I was formulating my plan of
attack. First I'd do a walk around at the antenna base to see if things
are good there. I noticed the connection between the coax and the
antenna was just a tad loose. I hand tightened it and then checked the
system with my
Never take cables completely for granted. I recently had a Pomona BNC
jumper, looked good, ohm'ed out good, but on my analyzer was BAD. It
was weird! Physically looked beautiful, tested out perfect with the
DMM, but wow, was it ever a baddie on the RF analyzer.
