I am looking for info on how to control a LDG PT-11P Autotuner
that was a "pull" from a Ten-Tec radio. I have spoke to LDG and
the only info I got was the manual.
It seems that it is controlled via a "data" line

maybe serial data??
I want to use a SBC or Arduino to control tuner for use on a QRP radio.
ANY info/thoughts/help would be great.
