[Elecraft] KIO2 not working

[james at kurtadler.com]

Alright, 
   I got the choke installed and I now get voltage out to the pins. I 
still cannot connect with my laptop, but I'm going to bring the K2 
into work tommorrow. The voltages I get on J1 are as follows:

Pin 1: 0
Pin 2: -9.96 or 13.68 (It changes as I move the dial or change 
anything on the K2)
Pin 3: .01
Pin 4: 5.59
Pin 5: 0
Pin 6: 5.71
Pin 7: 0.01
Pin 8: 14.24
Pin 9: 8.07

I had a 14V Supply in the K2 and had nothing connected to the J1. I 
can still hear the oscillation at 16.292 mhz.

I did install the jumper between pins 7 and 8 on the PC side of the 
serial connector if that makes any difference. Do I have to change 
anything on the computer for that? I see this choice was optional..

Thanks,

James KB2FCV
