Don: For what it may be worth, I was in contact with Don, N4ZZ, the other day and he was complaining about a momentary, periodic drop in power output from the K-3 of approximately 50% while driving his amplifier. He was using the latest firmware version 3.79. He had not had that problem before. I had downloaded version 3.79 but have held off installing it until we see whether there is in fact a problem. I am using version 3.77 and the output is quite stable as it has been all along. I think I should mention I have seen one or two other references regarding similar problems from other posting as well. Although Don's problem is not exactly the same as Tom's it does mention unstable power output on sideband. Perhaps this warrants further investigation.

As Joe has mentioned, do the power calibration, it will help. The power control mechanism does use the data obtained from the TX gain calibration, so yes they are related. 73, Don W3FPR Juha - oh6os wrote: > Not so good behavior on the contest, where is alltime tuning. > > juha - oh6os > > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
