RIght on Denny.
I can remove a splinter from my finger, deliver a calf but would not
want to set a broken leg.
I would leave the avionic in the plane and fly to a good shop and let
them use their equipment.
They set things more accurately with their signal generator. Cables
and antennas can also make a difference. Besides, you are now legal.
I fly for some attornies, you want these dogs on your side because
they can bite very hard.
