[Elecraft] PX3 computer interface to KX3

[Bill Frantz]

I'm sitting in New Hampshire and I find I can't get my computer 
to talk to the KX3 when it goes through the PX3 using the 
ACC1-PC jack. The computer can talk to the KX3 when plugged in 
directly to ACC1 jack on the KX3, and the PX3 can get the 
frequency data when plugged into the same jack.

I have the same problem with both wsjt-x and RUMlogNG, so I 
don't think the problem is in the computer software. The USB 
<--> RS232 seems to be working, so I suspect the PX3.

Does anyone have any suggestions for something to fix to get 
both the computer and the PX3 to talk to the KX3? (I'm low on 
test equipment here, but I do have a DVM.)

Thanks - Bill AE6JV
