Suitcase Transmitter-Receiver B-2

The B-2 was designed and produced by Polski Wojskowy Warsztat Radiowy (Polish Military Wireless Unit) in Stanmore UK, in the same time as the A / AP series of clandestine radios, also under the direction and management of Tadeusz Heftman (chief constructor of PWWR and pre-war pioneer of radio amateur in Poland; call sign TPAX).

The B series was ordered by the General Staff of the Polish Army (Division II; in exile in the UK), and unlike the A / AP series, the B / BP series was intended for field use (larger antennas), mostly for use by the Polish Home Army for internal/domestic communications.

Receiver frequency coverage: 3.5 - 15MHz in two ranges 3.5-8 and 8 - 15MHz.

Transmitter frequency coverage: 4 - 15MHz in two ranges 4 - 8 and 8 - 15MHz.

Transmitter power 15 - 30 watts.

Successor to the B-2 was the BP-4 with a similar frequency range.

The British B2 Suitcase Transmitter-Receiver Type 3 Mark 2 is a different design.
