After replacing my K3 DSP board with the upgraded version, I found that my watt meter calibrations were way out of spec. I redid the low power cal and the K3 now tracks my Bird 43/HP RF VM / oscilloscope combo almost perfectly as it did before. However, no matter what I try, I can't get the HP watt meter in spec. When I do the calibration at 50W, the K3 puts out 100 W when 70W is selected. I finally ended up calibrating at 100 W, but of course everything is way out of spec below 90W and WMTR HP is maxed out at 180. Before the board switch , the K3's power meter tracked my other instruments within a few watts. I've done multiple re-sets and gone back to earlier SW versions but no luck. K3 S/N 489; 4.12, 1.13, 2.60. Any suggestions?
By the way, the upgrade improved the audio. It seems smoother or less harsh than before especially on CW. Purely subjective! 73 Gord VE7YU ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
