Roger,

I forgot to mention, that like yourself I am licensed radio amateur
[W8/G4DYR] and have the in-depth technical understanding of the avionics
fitted in the Archer.
If asked a similar question by the DE, I too would probably head off down
the full electronic technical path to describe how it worked :-)

Is that called "trick the man who holds your family jewels in his hands"
before the flight portion of the check ride?
