I added two 1n4148 diodes, cathodes to the former ALC pin of the
connector and anodes to the dit and dah lines that go to the paddle.
Then I connected that
The N1MM documentation shows a simple circuit for keying via DTR/RTS or
parallel port using a 1K resistor and an NPN transistor (2N or equivalent):

Jim,
Since the K2 has a positive key voltage, an NPN transistor is necessary. (eg
2N, 2N3904, etc) Alternatively, one could use an enhancement-mode N-channel
FET (eg 2N7000, etc).

Hi Ted,
For keying my K2 I use a special CW-usb cable and that works fine in N1MM
You can find this cable on Alieexpress or Ebay

Ted,
You should be using the special cable from the PC (or USB to Serial
adapter).
That cable has no RTS or DTR wires in it, so it will not work for
sending CW from N1MM. In other words, DTR and RTS are not implemented
in the K2.
Do NOT try to "fix" it by plugging the USB to serial adapter

Remember that the DB9 connector on a K2 is NOT a standard RS232
connector. Study the manual. To send CW via the computer serial port, a
"level shifter" is needed. It's been a

Hi all,
Many thanks to all who replied. I updated N1MM logger to the most recent
version, re-edited the macros in the manner described by K4MTX in his blog
(who did it for the KX3) and it seems to work with the K2 as well.
There seems to be enough space in the connectors of the pseudo-serial
One of the N1MM+ developers solved a CW stutter problem today for one of
our users, which was caused by latency in a USB-to-serial adapter. The
solution was to make sure you're using an FTDI adapter, and go direct to
the manufacturer for the latest version of the driver.

Hi all,
I was thinking about using my K2 with KIO2 interface together with an
existing N1MM logger installation in the CQWW contest this weekend. My
understanding is that N1MM does not directly support sending the KY command
to the rig's control interface.
However, I found some hints about
Ralf,
I cannot answer your N1MM question, but I can answer with certainty
about the K2 'special cable' -
Yes, the 'computer' end of that cable can be plugged into a USB to
serial adapter.
Just do *not* plug the adapter directly into the K2 AUX IO connector.
You may find some USB to serial

I am aware of the approach that keys the K2 with the one transistor-circuit

Knowing now that Elecraft radios with IO interfaces have the ability to

If it's a Windows OS. You can change the baud rate by going into

Hi,
Fired up my K2 Elecraft (#4927) with N1MM Logger program and found out that
it will only work with 1 stopbit (remaining parameters are confirmed).
This is in contrast to both the n1mm manual (use default Kenwood parameters
of 2 stopbits) and the K2 KPA100 manual saying that 2 stop bits
time
between characters should look just like an extended stop bit. On the basis
of that thinking, it should work with any number of stop bits - from one to
infinity.
