Dale,
Thanks for the suggestion. I ran the test on both K3s and they are exactly the same. The range is from 240 (fully clockwise) to 02 (fully counterclockwise) If I turn the RF gain slow enough I can see both rigs incrementing or decrementing (depending on turning direction) 1 count at a time. /Bruce From: Dale Boresz [mailto:dmbor...@gmail.com] Sent: Friday, December 15, 2017 10:12 AM To: Bruce Meier Cc: Elecraft Subject: Re: [Elecraft] K3 / RF gain - S meter issue Hello Bruce, Just to rule out any electrical or mechanical discontinuities in the RF gain control itself, you can use the CONFIG > SW TEST > SCN ADC option to examine the ADC reading as a function of rotation position for both RF gain pots and both AF gain pots. In order to be able to see the "SW TEST" option, you will first have enable "TECH MODE" by setting "CONFIG > TECH MD to 'ON' Once you've selected SW TEST > SCN ADC, slowly rotate your rf gain control from one extreme to the other while watching the 'steps' in the VFO B display, looking for any sudden step changes. The values I observe run contiguously from 002 at full CCW to 239 or 240 at full CW. Good luck with your troubleshooting. 73, Dale - WA8SRA ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
