I long ago built this into my K2. I used the wire intended for ALC, which I
don't use, connected to the DTR pin of the DB9.
The ALC line conveniently goes to the K2 control board through the connector
with the RF board. I put the transistor on the back of the control board, along
with a pair of
I have done it both ways. The transistor interface and an outboard
keyer, the Winkey USB.
I prefer the Winkeyer because it makes it easy to hook up the paddle and
computer. I don't know of a contesting program that doesn't support it.
It also avoids the Windows multi-tasking issues which can o
All of the suggestions made about the cable and the COM settings are valid.
I'd like to add one more: the type of RS-232 hardware in your computer. I
could never get my K2 to run with RS-232 dongle (this was before the K3
dongle was available) and have used a "real" RS-232 card in the shack

One N1MM/MM+ thing doable on a K3/3S you cannot do with a K2 is to use DTR
or RTS to the transceiver for logging program driven internal CW keying.
It's not in the K2 firmware, and the leads are not in the K2's DB9 jack.
You have to break out the keying and provide *some* external device to key

The K3 can use a standard serial cable, the the K2 *cannot*. The only
connections for the K2 from the computer is pins 2, 3 and 5 in the cable
- those are TXD, RXD and Signal Ground.

The DB9 connector on the K2 is NOT a standard RS-232 port.
I believe there is a wiring diagram for the necessary cable in the KIO2
and KPA100 manuals.
You may have dodged a big bullet.

Phil,
First, set the baud rate at 4800bps - that is the maximum speed of the
K2 (the K3 can go to 38400 baud).
Did you test the setup before Field Day? If it worked OK during that
pre-FD testing, all the settings should have been correct.

I got the K2 out for Field Day and it performed great! I’d never used the K2
with a computer, so I hooked it up and set up N1MM for the contest.
I was unable to get the function keys to operate and N1MM was a little
unstable, sometimes locking up. I was able to log contacts, but couldn’t send
