The old "100 mw input" limits apply only to certain types of devices,
and in general "intentional radiators" have to be certified for
compliance with specified antenna arrangements.

The device in question was a Heathkit CB walkie-talkie with a not so super
regenerative receiver that I built in 1963. I suppose that radio was an
"intentional radiator," but its intentions were pretty weak.... Oh, well, it
led to a ham ticket.
