Dave AB5S posted these pics some years ago showing the radio position on US Navy patrol blimps.

One shows maybe a ZB-3 , LM and GF xmtr

then two RU rcvrs and a GP-7 xmtr at the bottom

The other shows a ARB rcvr, LM and what looks like a junction/ control box. Then a

ARB , ATB metering , ATB just behind his head. GP-7 at the bottom
