Hello again, Update to my last post: I turned everything off, went and had a cup of coffee, came back and tried the RF gain calibration routine again with K3 Utility - worked just fine this time. So, not sure why those errors. I had turned everything off and re-booted the K3, restarted the utility etc in previous attempts, with no effect. Must've been the cup of coffee :)
So now on to another question: After the RF calibration, I re-did the S-meter calibration using the XG3, with the K3 in ABS mode, PRE OFF. SMTR OF = 21, SMTR SC = 14. With these parameters, the scale is very linear and pretty much spot on: S9 @ -73dBm, S2-3 @ -107dBm, S9+40 @ -33dBm BUT, when I disconnect the XG3, so nothing is connected to ANT1, the S1 bar flickers on and off. I can't stop this flickering S1 without readjusting the parameters and throwing out the rest of the calibration. The S1 does turn off if I narrow the bandwidth to less than 1.5khz. I've been doing the calibration in CW mode but with bw set at 2.8khz. Is this flickering S1 with no antenna connected "normal"/expected? Intuitively, I feel that no input should give no bars, but perhaps that simplistic. 73, John VK7JB -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-s-meter-calibration-parameters-and-flickering-S1-tp6418969p6418969.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
