Skip,
I looked at your patent and could not believe my eyes. You patented a
tone detector and a beeper. One could have argued that it covered the
original "beeper" pager. You could have owned the entire paging market
(or did you?). Amazing and disheartening at the same time.
It is amazing to me how patents work (or sometimes don't).

Wish I did, but I didn't! I think the value of the circuit was its
reliability, which is why I chose the monostable multivibrator as a
basis. The idea of a tone detector and beeper was probably already
patented, or probably too obvious to be patentable.
It was enough to kickstart the weather alert radio industry and
fortunate to retire at 43 as a result.
I definitely have been blessed by ham radio!
