“The Coastwatchers”, Cdr. Eric Feldt, 1946: The 1939 radio ‘3B’ required 12 to 16 porters. The heaviest piece was the gas engine generator, 70 lbs.

Naval Intelligence foresaw these points as future handicaps and drew up plans for a new radio, but when it was received, it was considered similar

but not as good as the 3B. “The Air Forces developed independently what we wanted, and eventually we were able to obtain it and even supply it

by parachute to coastwatchers. In the meantime, however, the 3B was our mainstay.”

 

Question: what were the two radios, RAN and RAAF, that were developed to follow on and possibly replace the 3B ?
