The TX Calibration issue I had with my K3 is now resolved. I followed Wayne's suggestions and the final one revealed that without the KRX3A the 50W Calibration ran fine. On replacing the subRX module and retesting all is OK. Though I had carefully checked all TMP connectors and the seating of SUBIN and SUBOUT boards before removing the subRX and found no issues, perhaps re-seating on replacing the subRX did the trick. Caveat: I did recheck (for the 3rd time!) the solder joints on the newly replaced P30 and P35 with a good magnifier. I could find no obvious dry joints or solder bridges, but did touch-up a couple of the pins on P35 while the rig was on the ESD bench for the subRX removal.
This experience was an object lesson in not panicking when things don't operate as planned and carefully going back over every step taken in the upgrade process. Sorry to have interrupted your Sunday Wayne. Big thank you to Elecraft and the support team. You continue to earn the respect and admiration of a big slice of the ham radio community. Have a great week! 73, David G3WGN M6O WJ6O -----Original Message----- From: Wayne Burdick [mailto:n...@elecraft.com] Sent: 16 August 2015 19:37 To: David Aslin G3WGN <da...@aslinvc.com> Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 TX calibration fails after KXV3B and SYN3A upgrade David, The KXV3B itself should have nothing to do with this unless it is damaged or installed incorrectly. Also, many K3 users have this same hardware setup along with rev. 5.33 firmware. So I suspect a firmware configuration issue. Make sure you're not in TX TEST mode; have crystal filters configured correctly; have the SUB IN board installed correctly (if applicable); TUN PWR set to NOR; TX ALC ON; 2-TONE OFF; TX INH OFF. Also try removing the sub RX (if applicable) and reinstalling the bypass jumper for the sub-IN module. Get it down to the simplest configuration possible. Please send all of the info to k3support and they'll contact you on Monday. 73, Wayne N6KR On Aug 16, 2015, at 11:16 AM, Dave G3WGN M6O <da...@aslinvc.com> wrote: > Mike (and all who have sent replies on and off reflector) - thank you. > I should have been more precise in my note.
