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………. Ray WA6VAB K3

It seems that there is something produced, but it doesn't exit the K3. I also did an EE INIT, ut no change. 73s Chris Am 24.03.2021 um 21:32 schrieb Harald Fritzsche (DD0VS): > Hello Chris, > > > > strange is, that your Display does not show a frequency, but it should. > > > > I had a water Intrusion in 2019 which causes several defects. > > I was testing along the Signal path to see the Signal (with RSP-spectrum > analyzer), that helped me, to find the defects.
