[Elecraft] N1MM

[Donald Nesbitt]

Hi Bob & all  - I've been using N1MM Logger with my K2 for a long time with
good results.

Particulars are: a P1 233 mhz 80 meg ram Win 98 SE old IBM laptop with a
"real" RS232 port and using N1MM Logger V 3.221.  I have not used the LPT
port for keying but run control and keying from the single serial port.  I
have not tried Logger Version 4.0. xxx on this machine.  More on that later.
When running the program I generally keep all other resources on the CPU to
a minimum and have never had a problem with speed, etc.

For keying, I use a simple one transistor interface built into an RS232 plug
with two (2) diodes on the keyline in order to use the "External Keying
Auto-Detect" feature of the K2 as shown in Figure 8-1 on page 92 of my K2
(serial #2028) manual.  This works like a champ!  You might want to try the
two diode trick when using the parallel port.

At the computer, I have a regular RS232 splitter (getting harder and harder
to fine these days!) and put my "keyer" on one of the splits and my K2
"special" control cable on the other.

If you look at the latest version of the Help manual, you will find some
information there that I wrote for using filter selection codes with the K2.

RE: Logger Version 4.0.xxx - I am running version 4.0.113 on another machine
with another rig and have not tried it with the K2.  The "other" machine is
a P4 2.4 g 512 meg ram Win XP Home laptop without any physical RS232 ports -
only USB.  I'm using this one with an Icom 756 Pro II.  The results here are
mixed.  Rig control for the 756 Pro II seems pretty flaky on my system with
some of the operations either not working at all or working intermittently
and frequently causing me to either shut down the rig and restart or do the
same with the program or both!  Tom is apparently working on actually making
keying via a serial port converter (USB to RS232) a possibility with version
4.  Keying via the parallel port apparently works with version 4.0.xxx
(although I never used it in V3 apparently it works very well) but if you
are using an XP machine (with either V3 or V4) you will need to download and
install a parallel port program that will support the LPT selection.  As I
recall, either dlportio.zip or port95nt.exe will do the job and information
is available on the web site.  I'm still hoping that eventually they will
get the keying going through the same USB to RS232 converter.  At some point
I may give LPT keying a try.  There has been lots of information on using it
on the group reflector.  Looks simple enough.

It is a very impressive program! Tom and the guys (and gals?) that work with
him on coding the various modules are very talented.  I'm still amazed that
the program is free!  73 es gud dx  --don n4hh K2/100 #2028 KAT100, etc, etc
