I use N1MM this way with one standard serial cable for single-port rig control and PTT/CW keying, using a USB to Serial adapter manufactured by Gearmo that uses an FTDI chip set.
I use just one of the four ports for the K3, the others are attached to other devices. <http://www.amazon.com/FT4232HL-Professional-Retention-Certified-Microsoft/d p/B004ETDC8K/ref=sr_1_1?ie=UTF8&qid=1354397714> My N1MM "configure" dialog shows COM2: Elecraft K3 and I've checked "CW/Other Details". When I click "Set" I get a page with COM2 as its caption. In that dialog I set speed 38400 No parity, 1 stop bit, and choose "CW" for the DTR (pin 4) and "PTT" for RTS (pin 7). Then I set my K3 configuration menu PTT-KEY for "RTS-DTR". In years past I would sometimes experience stuttering from CW keying near the end of a contest about the time I entered each QSO and went to WinKey as a result. In recent years I haven't found CW keying from a serial port, even with this USB adapter, to be a problem. I'm using Windows 7 64-bit and a reasonably modern (last couple of years) Intel chipset. 73 de Dick, K6KR -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of aa...@aol.com Sent: Saturday, December 01, 2012 1:16 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 rig control/CW serial interface Is there an interface commercially available that combines CW keying and K3 rig control (from N1MM type software) into a single serial cable? I think K1NU used to make these for Yaesu radios, but I'm not sure they are available any more.
