Please continue to keep this one live on the reflector as I am also having problems with mine and will use your findings to help me.

I confirmed the 5th step on page 11. It is indeed set for U8-4 instead of U6-25. I also tried it here at work on another machine. It's a pIII something or other. It's a desktop PC. It has two serial ports. I verified all the port setings in device manager matches what is called for in the manual - no dice. We use this machine all the time to connect hyperterminal to routers and such, so I know the port is good. I double checked the voltages on the KIO2 and everything looks as it should... I'm pretty confused..

I put the jumper in and have tried several programs and have no issues with it. I don't, however, key the transmitter from the keyboard. Of course you could always lift one side and check. You should also confirm that the 5th step on page 11 results in seeing U8-4 instead of U6-25. Somehow mine got switched back to U6-25 and nothing worked until I changed it back. At this point, I would definitely suspect your laptop. How old is it? The last laptop I bought in 1999 didn't have a serial port. Are you using a USB emulator?

The voltages seem to line up relatively close. I'm not sure if pin 2 of J1 is supposed to change from -9 volts to +13 volts when anything is changed on the k2 (frequency, mode, etc).. But it appears to be doing something. My only bit of confusion is whether having the jumper on pin 7 & 8 of the PC side serial cable connector has anything to do with my problem?

First, check Device Manager to see if you have any COM ports listed (it's not enough to just have a physical serial connector on the laptop). While you are there, if any are listed, make a note of the numbers - probably 1. Then in the set up for whatever program you are using, make sure that that number is selected. Hope the simple approach works.

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..
