[Elecraft] K3 + Palstar AT-AUTO + SteppIR Vertical + MicroKeyer 2

[Joe Subich, W4TV]

As documented in the microHAM microKEYER II manual, there 
are TWO auxiliary data outputs available from microKEYER II. 

The first output is the CI-V jack (3.5 mm).  MK II can be 
configured to provide an Icom compatible "transceive" data 
broadcast with selectable data rate (1200 - 19200 bps) and 
CI-V address.  Frequency data can be selected from "trasmit 
frequency,"  "receive frequency,"  "operating frequency," 
(shifts between TX/RX), VFO A, VFO B or "Sub RX frequency." 

The second output is a TTL serial port the iLINK port (pin 
functions are documented in Appendix A of the manual).  
The "iLINK" port can be configured to output control data 
(transmit frequency to prevent "hunting" when operating 
split) for the SteppIR (original controller) in SteppIR's 
native mode.  Use of SteppIR's native command set inhibits 
transmit when the SteppIR elements are moving.  This port 
can be used with a TTL to RS-232 converter (or the microHAM 
iL/ST cable) to connect to the DATA OUT port of the SteppIR 
controller.  

It is trivial to use the iLINK port to control the SteppIR 
via the SteppIR Data Out port and the CI-V port to control 
the AT-Auto (configured for an Icom transceiver).
