Keith _always_ gives good advice. I would add one thing. Make sure the AUXIO cable is disconnected from the back of the K3 when you do your testing. If it is directly connected to a KPA500 or KPA1500, it just may keep the K3 from shutting down. We don’t remember if the LCD will go blank in this situation, though.
This is why we specify AUXIO cables for the KPAs with pin 8 (the power-on pin) disconnected. 73, Jack, W6FB > On Oct 14, 2021, at 7:40 AM, Jim Sheldon <w...@cox.net> wrote: > > Turned on my K3s this morning and got a blank screen.
