Re: [Elecraft] K3 Power Creep
Guy, K2AV contacted me direct and suggested I rerun the power calibration, something I had not done after loading the latest firmware. The power creep has been significantly reduced to the point of acceptability (2 to 4 watts vs 15 - 20 watts). Thanks, Guy, and shame on me for not trying that before I spoke. 73, Dan __ 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

Hi Ron, I can't comment on whether this is normal or a problem, but I can confirm that I see the same thing in AFSK-A mode, so it's not just you :-) I believe it is ALC related. 73 -- Joe KB8AP On Feb 15, 2009, at 1:25 PM, Ron W3ZV wrote: ...
