============================================

Some of the Raytheon sets use a hollow square to denote a target that
is being tracked. My guess is that the set inadvertantly went into a
mode where it thought it was tracking a distant object.


Nope, not something that a RADAR as discribed could do. These were
analog Reatime video displays, and didn't have any ARPA features
included.

I suspect that it could have been one of the early Xband Transponders
but how it could be triggered at that distance without being at some
altitude, would be an interesting question.
