Problem with TX on K3 3001

[Lu Romero - W4LT]

Chris:

On my rig's (#3192) return from Aptos for the replacement of
the Quad Encoders, I received the same error.  I tried to
initiate tune output and the tune button would send out a
6.5w carrier when set to 10w, then switch back to receive,
but the TX LED would stay on.  It didnt do this before...

The factory had loaded 3.30 (I sent it in with 3.27)
firmware and K6PZ had done the calibrations upon installing
the new encoders (Or so it says on the work order).

I figured something was awry, so I did the power
calibrations again into my load with 3.30 loaded and
received the same error you got.

I backreved to 3.27, tried to calibrate and got the same
error again.  On a whim, I upgraded to 3.41, ran the
calibrations and the error went away.

I dont know what caused this, but the radio seems fine now,
running 3.41, 10w is 10w and no issues at all in a week of
operation.

I didnt report the problem because I have not experienced it
again, I thought it was a quirk with my rig, but now since
you reported it, I thought I would let you and Elecraft know
that I saw the same thing and how I got rid of it.  

Maybe its just a fluke or has something to do with the phase
of the moon  :)

Greetings all, I have been following the reflector for a
while, but this
is the first post I have made, so be kind ; )

I was doing some testing locally with a friend, and he
noticed a warble
on my cw tone.  Upon further investigation, I have noticed
the
following:

When tune power is set to 10 w, it seems to show only 6.5
watts out.

When tune power is set to 100 w, it shows 100 w out.

I tried to run the tx calibration sequence, and it fails
doing the 5
watt cal with this message, similar to the tune power output
issue..

Starting 5 watt calibration
Calibrating at 1.900 MHz
IsSamplingComplete: Unexpected response
"DS@@@@1\xB1>I\x80\x88;" to
"DS;" State 153
Calibration power settled at "  3.9 W ;"
5 watt calibration failed
Elapsed time: 8 seconds

Anyone have any ideas on this?  Me thinks my baby is broke
:(
