I wired a transistor and a resistor or 2, and a 1/8" jack onto the 9 pin plug that plugs into the serial port. I think I used a PNP (like a 2n3906) or a FET (like a MP102) but I can't remember. I used some of the voltages on the serial plug to power the buffer. What ever I did was the obvious thing to do, it wasn't fancy or cleaver. If I get the chance I will pull it apart and give a clearer description, but it would probably take less time just experimenting with what you have on the bench than that waiting for that.
One thing I found, is using a usb winkey, a usb serial port, and the flex usb to parallel converter, I lost the ability to send code without errors. There was too much traffic on the USB line that was temporally related and some things got out of sequence. It took me a while to figure it out since I had just purchased a new paddle and I figured it was my lousy set up on the paddle (though it was a Begali and those are like impossible to set up incorrectly). I did not have the problem if I used a standard serial port or if I used the CW jack on the back of the radio. 73 W9OY ____________________________________________________________________________________ TV dinner still cooling?
