[aprssig] N1547C tracker

This is another great example of people having too much fun arguing to pay
attention to the facts. The very first post, and the web page about this
flight, explain that "Power is via a cigarette lighter plug."

I think it would be simpler and less inconvenient to pilot and passengers to
pull a cigarette lighter plug out of the panel rather than throwing the main
switch, don't you?

You're splitting hairs here about as fine as possible.

If the only way to turn on/off the tracker is to turn off the master switch
in the aircraft, then making a call to the pilot in the air (not legal
on a cell phone and telling him that he must turn off the tracker would
require that he turn off the master switch to the airplane. That's not going
to work very well.

And splitting hairs the other way. If the tracker is only turned on by the
pilot physically turning on the master switch in the cockpit, then that
IS specifically turning on the tracker, no matter that other powered
in the aircraft is also being powered on.

This  operation is blatantly illegal... period... and I hope nobody 
'officially' brings
it to the attention of Riley.
