FWIW, my late Uncle John was a radio op on a B-24 "Hap 'n Hank". He related that they, in the SW Pacific used cw for actual traffic. Voice for inter-group. My one regret was that he never got to see my SCR-387 setup. Well... maybe more...

As I understand it from a previous exchange on the ARC5 forum, CW was very seldomly used for communication.

Most was done by voice: AM in those days.

Sometimes, CW was used unofficially in bombers (B-17, etc.) to signal the home airfield that they were on their way back.

But this info is anecdotal, not official.

Subject: [ARC5] SCR-287 (BC-375 & BC-348) WW II Operational Question

Hi Everyone

Was there any preference to the mode used during missions? I'm specifically referring to the time before bombers were equipped with the SCR-522.

I checked my books and did web searching, but was not able to find an answer. I find numerous references to HF frequencies used, but nothing that indicates voice or CW.
