[Elecraft] operating HF / KX3 in a Tesla Model S

Hello elecrafter, I am thinking operating my KX3 in my Tesla and have some questions: 1.  Is it ok to direct drain DC supply from the cigarette lighter socket since there is no ignition system in the Tesla? 2.  The body of Tesla is aluminium alloy (if I am correct.  How can I ground a mobile

Hi Irwin, Looks like you found a bug. But as a work around I would suggest setting the SVGA waterfall height to operate on its own, independent of the P3's waterfall height. To do that, press the MENU button on the front of the P3 and using the encoder, select SVGA Menu. Then select 'WfEn'

That's harmonics which the FCC regulates to -43 dBc or better, better being a bigger number, on 160-10m, and -60dBc for 6 meters and up. That number IS regulated. That is not the same as two tone TX IMD which is specified by Elecraft as around -30dB, and NOT regulated by the FCC, because most

It certainly left the factory working on 17 meters, because we do a 100% test on all bands for TX harmonic suppression. My working theory is that the unit was damaged in shipping. We may never know. 73, Wayne N6KR On Oct 18, 2016, at 2:51 PM, n...@comcast.net wrote: > Hi Eric, > Just

I have seen a similar issue with my PX3 but it may not be the same or it may be related to the root of the problem. What I notice is what "in the old days" would be switch bounce. What I notice (like you) is when I turn the knob fast the value bounces around but doesn't go anywhere. I find
