[Elecraft] Can't get KXPA100 to turn on when PX3 is attached after SOTA trip.

[Kenneth Christiansen]

Hi Terry

I never saw anyone answer your question and I just got home from work so I could not do it earlier. I just took my KX3, PX3 and PA3 camping this week end and had the exact same problem you describe. I had one cable in the wrong place so here is what you need to make sure you do. The cord From ACC1 on the KX3 must be connected to the ACC1-XCVR on the PX3. The cord from the black box of the control cord of the PX3 must be connected to the ACC1-PC on the PX3. 

All the other cords can be plugged in or left out and of course the PX3 will not work properly if they are left out but the PA3 will work just fine as long as those two cords are connected. 

I hope this helps you. I lost about 4 hours of operating time until I figured out just what I needed to connect to get it to work.

73 and good luck
