Update: - reseted all TMP connectors - already changed the pin headers at the KPA3 (had the 12V ERR some months ago), since then radio was good for some hundred QSOs - no transverter available - serial number is 1532 - K3 receives without any problems - uploaded the newest firmware
No change. I don't have a spectrum analyzer, but I will look with my eyes if there is something noticeable. 73s Chris DL1MGB Am 25.03.2021 um 02:35 schrieb Ray: > > > > > Harald > > I think you need to start at Ground Zero,,,,,, > > Go to your Elecraft Utility > > And connect to the K3 Radio and verify > > The Firmware is present (05.67 ect) > > I would go to the Basic mode of operations. > > Set K3 to SSB operation Upper or Lower , Freq middle of band. > > Set radio to PTT (not VOX) Ant 1, load to Ant 1. > > Verify on K3 DVM , voltage is 13 volts. > > Push Tune button (long for TX – with RF) > > Adjust PWR knob Clockwise for Max RF power. > > Take readings……….
