[Elecraft] Connecting a BigIR

[Andy Durbin]

"My question is exactly where to connect the SteppIR control box to the radio."

The simple answer is do not connect that way.  The direct SteppIR interface with a Kenwood/Elecraft rig is very poorly implemented and may cause the SteppIR to tune at beginning and end of transmission.

Far better to use a separate application or hardware interface that sends the SteppIR controller only the TX frequency.  I have been using PstRotatorAz for many years.  Others have used DXLab Commander secondary port.

My experience is with a 2 element SteppIR but the tune on TX problem will be just the same with a BigIR.  I wrote a paper on this issue about 10 years ago but, to the best of my knowledge, SteppIR did not fix it in any later controller versions or models.
