I had similar problem during the build of my 2nd K2. I had the experience during the First test stage - very few parts on RF Board. Consequently I re-soldered many pads on the FP and Cont boards, to no avail. I discovered that I could press DISPLAY button and Menu button and get mainly correct responses, but no tuning. All voltage and resistance tests were OK. I resorted to doing a RESET on the EEPROM (press 4+5+6 simultaneously while turning ON power). After that, all has been well since. If you do a reset you will loose some EEPROM F/W setting you have made - filter configs, etc. Check the supply voltage first, just in case it is falling too low. If the problem persists after reset and/or if it works but becomes intermittent, you should re seat the FP and Control boards in their connectors and consider inspecting/re soldering control board pads. 73 es Good Luck, Al WA6VNN In a message dated 3/30/2008 6:37:47 P.M.

Does anyone have any suggestion other than sending the rig to Elecraft? When I power the K2 up, it is like it has no antenna connection (I have the KAT 100 external tuner that I use with the rig). When I also power up only a few of the letters for ELECRAFT appear on the LED Screen. Maybe 3 or 4 letters only and the S meter has three bars then a few blank and then 2 filled in. The rig sounds like it is almost muted or at times no audio. Also when I power up, the KAT 100 shows the rig in the low power position even though I have the pot set for 100 watts. It can take me about 5 to 10 minutes of turning the rig on and off until it will then function normally. Once normal it is fine unless the rig is off for about an hour. If I turn the rig off for an hour and come back to it it will not start normally and I have the same issues all over again. I have checked all of my connections into the rig especially the power connections and antenna connections. It kind of reminds me if I had an IC that was somehow failing somewhere? Thanks for the feedback! Best 73's -- Norm K9NK _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
