K3 ERR TxG

[Jeff Wandling W7BRS-2]

Just tuning up a new amplifier, less than 10W.  Previous to this
(minutes) running fine barefoot.

Have K3/100/KAT3

Symptoms:  During auto-tune, instead of showing SWR it shows "--", and 0.0
W output in VFO B.

Also, after holding TUNE, the VFO B reads "ERR TxG"

Focusing on the K3, the manual says to contact Elecraft about ERR TxG,
which I have done.  But in the mean time, what else can I try?  The manual
says not to adjust anything.. I'm sort of stuck..  If this has happened to
you, what did you do for resolving the problem?

Thanks,

-jeff

Have you completed the Calibration Procedures section of the owner's manual?
These steps aren't optional.

If you haven't, perform the Synthesizer Calibration first, then the
Transmitter Gain Calibration which can accomplished fairly quickly with the
K3 Utility.  See the Configuration Tab, "Calibrate Transmitter Gain" button
and the K3 Utility Help page "Transmitter Gain Calibration".  You'll need to
connect a dummy load to one of the K3 antenna connectors for this
calibration.

If you've done all these steps, there's a different issue that probably
deserves an e-mail to K3Support

Thanks.  Already emailed Elecraft.

re: Calibration; Done all those steps  months ago. Yes, I've calibrated
per manual. It's been running fine for months.

Not a new build.  Just added a new outboard linear and was tuning it.  Was
getting zero watts output.  Disconnected outboard amp and began trouble
shooting the K3 itself barefoot.  Now at the point where no output and ERR
TxG when using TUNE while in BYPASS.

I have been using my coarse knob on SSB to make simple fast rate tuning of
SSB signals. It is just super!  On CW, however the rate doesn't
automatically change that I am aware of or have I missed somewhere. Because
I jump between the two I am wondering if I missed a per mode change rate?  I
increase bandwidth using the XFIL setting (I set up CW to work with the 2.8
8 pole and also have a 400 8 pole as well.)  Or, is this something that
could be added in firmware?


73,

CONFIG: VFO CRS

Set the step size you want for the current mode.  Change modes while in
this menu and set the step size for the next mode, mode.

I use this all the time in conjunction with the RIT knob.  Step size
changes according to the mode I'm in.
