[Elecraft] Dead PX3?

[sancho]

I have experienced similar issues only after a complete power down (KX3, PX3, KXPA100, computer, AND power supply). Both the PX3 and the KXPA100 act like they have a mind of their own. The system slowly rights itself... first KXPA100 comes on and cycles with the KX3, then the PX3 just starts working rando. Once all three are up and talking to each other, the system is good until the next time I do a complete power down and disconnect the antennas.

Before you ask, I have tried to reseat all cables, I have checked to make sure PA is enabled in menu, and I have pushed the power on switch on the PX3. I have also switched to different USB dongles (I have 3 Elecraft KXUSB units).

My solution is not to completely shut the station down unless I have to because of lightning.

Make sure the plugs are fully inserted into the ACC1 connector on the KX3 and the ACC1 XCVR connector on the PX3.
