"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.
