I'm researching "hot mike/mic" for an upcoming Wall St. Journal column.
OED3 includes a cite for "hot mike" from 1937 in its entry for "hot" (sense
9h: "electrically connected or charged; turned on; live"). So far I've
antedated that to 1930:

Broadcast Advertising, Apr. 1930, p. 16, col. 2
Broadcasting has its own language, a few words of which are quoted here
from the glossary that is running serially in the "Voice of Columbia."
"Hot mike" -- A microphone in operation.

Bangor (Me.) Daily News, Feb. 10, 1931, p. 9, col. 7
A glossary listing words and phrases peculiar to radio engineering has been
compiled by Engineer Irving Reis -- the Dr. Vizetelly of the Columbia
Broadcasting System=E2=80=99s technical staff. [...]
Hot Mike -- Microphone with current applied. A "dead mike=E2=80=9D is one t=

shut off.

Can anyone find anything earlier? An Internet Archive search suggests it
may be in the Oct.  1929 issue of National Radio News, but that item is
currently unavailable:

I don't see "hot mike" skimming through the PDF for that issue here:
