Hello Chris, all,
According to your current consumption the 10w PA driver is working, but KPA3
gets no input or has not 12V.
Check CB1 CKT BKR (KPA3 page 1 of 2 in K3 schematics) and check if TR-Switch
gets plausible voltages (KPA3 page 2 of 2, 7R and 7T).
Since there is no plausible idle
I am not sure if there is a frequency shown when in TUNE mode. My memories tell
me that the top line shows the SWR and the bottom line shows the power.

Update:
- reseted all TMP connectors
- already changed the pin headers at the KPA3 (had the 12V ERR some months
ago), since then radio was good for some hundred QSOs
- no transverter available
- serial number is 1532
- K3 receives without any problems
- uploaded the newest firmware
No change.

I think you need to start at Ground Zero,,
Go to your Elecraft Utility
And connect to the K3 Radio and verify
The Firmware is present (05.67 ect)
I would go to the Basic mode of operations.
Set K3 to SSB operation Upper or Lower , Freq middle of band.
Set radio to PTT (not VOX) Ant
Does it receive?

Hi Harald,
spectrum analyzer and more space on the table would be the best, but both not
available :-)
Additional information:
- internal voltage / current (DISP)
Standby: 13.8 V / 0.86 A
Tune: 13.4 V / 3.20 A
And still no power output on the external wattmeter.
It seems that there is

The quickest and easiest method for zero-beating the NCS on an SSB net
is just what Andy described . . . tune for the most natural sounding
voice. I suppose someone with lab instruments and scopes might come up
with something more sophisticated But, as others have pointed out,
True ... the NCS is, by definition, the net frequency. One can zero
beat CW and AM to within a Hz or so and with today's radios, you will
even stay there. What's to "zero beat" in a SSB signal?

Took the words right out of my mouth. And how does a NCS know check-ins are off
frequency, especially if it's a YL?

For SSB, I use the same.

O.k. I'll bite. I started in amateur radio long enough ago to know how to use
a BFO and to know how to zero
Probably a good time to remind newcomers . . .

Paul,
There was some guys on 3.816 LSB when I started listening about 1/2
before our net time. The typical kind of thing where someone would
say something, then a couple of minutes of silence, then someone else,
then a bunch of ID's at the 10-minute mark.
Rinse, repeat. This kind of
