[Elecraft] K3 use with steppir antenna

[Joe Subich, W4TV]

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.
