"Set, Complete, Radio" is what I once saw in a Signal Corps document from
the 1920's or earlier. But I've long since forgotten what the document title
was. It's meaning as "Signal Corps Radio" I suspect we have the media to
thank for. Like calling a BC-611 a "Walkie Talkie". In any case, I haven't
been able to turn up a Signal Corps nomenclature chart here today, only Navy
and AN.
