BC = Basic component of SCR
The BC 191 Is the transmitter part of SCR 187, this transmitter is also a part of other SCR sets like like SCR 193 as used in 1/2 ton Dodge command cars .
The set appears to be intended for air to ground liason use, and it was fitted in Piper Cubs and similar aeroplanes with a 12V System ?
The BC 191 is a 12V transmitter . |
There is one enormous problem with the BC 191, these days: Audiophools.
The transmitter uses 4 large triode valves (VT-4C or (civilian) 211), and these are highly prized by the valve audio amplifier crowd, to the point of ridiculous prices being paid (500 USD for a pair). As a result, any transmitter you are likely to find will have had its valves "liberated", and they will be neither easy nor cheap to replace (unless you are very lucky).
