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.
