ARRL published a circuit using it in many of their
handbooks from the '60s.

I just pulled out my '65 ARRL handbook and there are two SSB exciters,
each of which uses TWO 7360's.

And there are two not-awfully-fancy receivers, each of which uses a
7360 in the mixer.

Man, somebody in the ARRL must've owned stock in that tube company :-).
