I would like to build my own auto tunner and need info on software. My plan
is to use a car ecu computer for the controller as it already has much of
the digital an analog interface I will need, is rugged and cheap at the
local scrap yard. Before someone yells "why are you using that for a
controller", the point is to use one for something other than its intended
purpose. I just thought an automatic antenna tuner would be a good use for
one.

When I retired from Intel, most ecu controllers ran their programs from
internal ROM which is not reprogrammable. Seems something like a PIC
would be a more logical choice.

There was a series of articles on a software-controlled tuner in qst a
year or two ago.
