W4GIW de W0XI,

I built a K3 kit with P3 last November (2014) and have been learning and
enjoying. Prior to that I had (and still have) a Yeasu FT450D with YT450
auto-tuner and SteppIR Vertical (33 foot max). Not sure if you are
referring to a yagi-like stepper? Anyway, for now here's how I've been
using the SteppIR vertical with the K3/P3 combo:

I have both the N3FJP and N1MM+ software and use both of them for
different things with the K3. Most recently I've been using the N1MM+
for generic logging (using a modified contest log) so that I can
record/change the frequency of the K3 from the keyboard and enter the
call, RST and exchange if any. I have not, at this time, spent the time
to figure out how to auto tune using the N1MM+ for the K3. For example,
If I start out at 14025 on CW, I'll enter that into the SteppIR control
box and then check the tuning with the ATU button on the K3. I seldom
tune more than +- 25 kHz from 14025 (all CW) so don't seem to need to
retune with the ATU button. I do watch the SWR display next to the
transmit power indicator, bar graph. Then hit the ATU button if necessary.

I do like having the N1MM+ log the frequency of the QSO (and the time,
etc), which it does, so I don't have to write anything down.

When time, I'll study how to merge the checking of the SWR with the
N1MM+ and the K3 auto-wise; guessing that is possible.

So I guess you could say I'm half-automized! Hi. 73, Uncle Phil, W0XI,
Lawrence, KS.

[Joe Subich, W4TV-4]

The simple way to use a SteppIR antenna (any version) with K3 and
logging program is to use SteppIR's 9 pin "Y" cable and RTS_S13
transceiver interface cable.

The common leg of the "Y" cable (DB9F) connects to the computer
serial port or USB to serial converter.  The "Radio" leg (DB9M)
of the Y cable connects to the "SteppIR" end (DB9F) of the RTS_S13
cable, the "Radio" end (DB9M) of RTS_S13 connects to the K3 (or P3)
and the "SteppIR" end of the "Y" cable connects to the DATA IN jack
on the SteppIR controller.

Configure the SteppIR Transceiver Interface Mode to Kenwood/Elecraft
at 38,400 bps, Set your logging program, K3 and P3 to 38,400 bps
and configure the K3 CONFIG:AUTOINF = NOR.

Turn on the Auto mode (SDA-100) or General mode (Original controller)
on the SteppIR.

The SteppIR controller will respond (follow frequency) to data from
the K3 in response to the logger's polling as long as the logger is
running.   When the logger is not running, the Autoinf=NOR setting
should cause the K3 to send frequency data every time the VFO knob
is moved.

Beware that *some* computer serial ports/serial to USB converters
will load the K3 data output lines when the computer is turned off.
It may be necessary to disconnect the cable from the computer
serial port/USB to serial adapter when the computer is turned off.


73,
