is an FM- transmitter, used in tanks during WW 2.
It uses 10 fixed frequencies out of 80 possible. In a drawer in the radio you find the 80 correspondent crystals.
10 of these are inserted in a special closed space, where two big resistors keep a temperature of about
33 degrees C.
It is part of "Radio set SCR-508" or "Radio set SCR-528".
By using the intercon amplifier BC-605, the radio sets could be operated by any member of the crew.
