I know nothing of Jack's case, but in the case of Dino, Lewis Patton was monitoring the frequency scanner during the flight and was getting strong sporadic signals. It was not constant as if a radio was on and left on. The signal would be strong one second then fade and come back strong again.

I did witness several radios out in the pits and down the flight line being turned on & off to make checks. Hopefully they all had the pin for their channel.

It would be truly sad to think that someone was trying to intentionally down someone else's aircraft, and I "Pity The Fool" if he is ever caught.
