Thanks Doug. Did the radio put out any RF when it failed to calibrate? I'm getting none when I key the rig. 73, David G3WGN

We solved the failure to TX calibrate by reloading the K3 Utility - the same one which worked fine previously. Reloading the utility is an easy thing to try. 73 Doug EI2CN -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Dave G3WGN M6O Sent: 16 August 2015 10:39 To: [email protected] Subject: [Elecraft] K3 TX calibration fails after KXV3B and SYN3A upgrade I'm hoping there is a quick fix for this (some fat-fingering or brain fade on my part is entirely possible) as the K3 in question is one of four heading to E6GG next month. Yesterday I upgraded S/N 4474 with KXV3B and 2 x SYN3As and while the panels were off, also did the 12V DC Out mod and gold connector replacement mod. I have a full ESD bench and wore a wrist strap at all times. After careful reassembly and TMP cable checks, I was able to update to latest firmware and enable synths and KXV3B. But TX Calibration failed with Calibration power settled at " 0W; " message. I have tried the following remedies: Panels off and examined all boards for correct seating. Examined all TMP cables for correct seating. Replaced panels. Re-attempted Calibration - same error. Re-flashed the firmware load. Load successful. Re-attempted Calibration - same error. Performed EE INIT Loaded a known-good prior configuration (from March 2015 well before the upgrade) Re-attempted Calibration - same error. Any suggestions for next steps gratefully received! 73 David G3WGN WJ6O -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-TX-calibration-fails-after-KXV3B-and -SYN3A-upgrade-tp7606337.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:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
