[TG9AJR Juan Munoz]

I have my K3 and just finishing installing my SteppIR small vertical
with the SDA100 Controller
and I also order the K3 Transceiver interface connector from the
SDA100 Controller to the K3.

Does any one knows how is setp up :
I assume from the DATA IN/RADIO in the SDA100 Controller to the ? on the K3 ?

Thank you and 73
