Actually Mike, you do not need a keying circuit using a serial cable with the K3. I run a direct serial cable from the computer to the rig and it works like a champ!
I did have timing issues with the K2 and N1MM and had to go to a K1EL keyer to resolve that. 73, Julius Julius Fazekas N2WN Tennessee Contest Group TnQP http://www.tnqp.org/ Elecraft K2/100 #4455 Elecraft K3/100 #366 --- On Mon, 2/16/09, W0MU Mike Fatchett (via Nabble) <ml-user+39166-1921107...@n2.nabble.com> wrote: > From: W0MU Mike Fatchett (via Nabble) <ml-user+39166-1921107...@n2.nabble.com> > Subject: Re: [Elecraft] K3: Configuring N1MM to send CW > To: "Julius Fazekas n2wn" <phriend...@yahoo.com> > Date: Monday, February 16, 2009, 11:42 AM > To key cw you will need some type of keying circuitry.
