Steve:
Yes, the Rigrunner I have is indeed the 4010 S.
So, it may well be one of those transistorized units you are talking about.
It has a switch on it where you can put it in several different positions to
activate various things.

Tom,
So which rig runner do you have? Most of them are just passive units,
where you input your supply or battery voltage into one of the jacks and
connect all your devices to the other jacks. But they do have one
model which has some sort of transistor switching involved. This one has
an "S" on the end of the model number. Since you had said that the
problem was the rig runner shutting down due to rfi, I figured that was
the one you have, but maybe not.
