B 30T

Radio Station. Same as B 30 but with the possibility to use also CW. Used also like secondary station on multiengine aircraft. In this purpose it had 2 remote controll box.

B 30mT

Radio Station. Same as B30T but modified to solve the stability problem. Main modification was the use of 6T tube instead of EL2 like MO and adjusting accordingly the circuit.

B 30T bis

Radio Station. Further implementation of the B 30mT. Main difference was the introduction of the interphone possibility. The B 30Tbis was used specially on multiengine aircraft for communications among aircrafts
