K3 1mW Calibration problem.

[Glen Torr-2]

Hi Elecrafters,

I recently installed the K144XV and was only getting 6 Watts out, I
had oerformed the 1 mW calibration.

To measure the power out of the KXV3A I attached an Elecraft 20 W
dummy load and TDS220 scope.

The power out measured 480 uW (440 mV p-p). To measure the power out I
used the MilliWatt Meter Calibration described on P49 of my manual,
rev. D2. I set CONFIG:KXV3 to TEST and held tune.

The menu entry name did not change to CONFIG:WMTR MW (am I missing
something here)?

I re-did the 1 mW calibration watching the scope and p-p output
voltages were typically 580 to 590 mV p-p (should be 634 mV p-p I
reckon).

Re did 5 W,  50W and 1 mW cal then getting 820 mV (2.1 mW) p-p using
CONFIG:KXV3 set to TEST.

In summary 2 problems:-
1) CONFIG:KXV3 to TEST and CONFIG:WMTR MW are not working for me.
2) The  1 mW calibrate in K3 utility 1.3.4.3 seems to deliver results
which vary from cal to cal.

Any insight appreciated.

Cheers,

Glen VK1FB
