Thanks for all the responses. I got this working pretty quickly yesterday. It took two iterations ... first time, I made the cable a bit too short in my effort to keep my desk neat - and had some of the connections off-by-one on the DB25 :-) The computer would key the radio but never unkey.
I figured that out and added a foot of cable and N1MM logger is happy... 73 de chris K6DBG P.S. http://pages.cthome.net/n1mm/html/English/Interfacing.htm has schematics, among other places. And Tom N0SS's board looks very nice, but I wanted it "today". I also wanted to put the isolation diodes in a (planned) box that will take computer, paddle and straight key... _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
