  • Notes
  • The desk top transceiver BC-312-M has a Dynamotor DM-21. It was designed at Signal Corps Laboratories Fort Monmouth, New Jersey and at least made by Farnsworth Television & Radio Corporation, Indiana. Frequency range is 1.5 - 18 MHz AM / CW. Ceramic condensers, steel instead of aluminium.

    There is a big range of BC-312: BC-312-A, BC-312-C, BC-312-D, BC-312-E, BC-312-F, BC-312-G, BC-312-J, BC-312-HX, BC-312-NX, BC-312-L, BC-312-M and BC-312-N. BC-312-HX and BC-312-NX work with 24 - 28 V DC with Dynamotor DM-21CX, the others with 12 to 14 volts. - with Dynamotor DM-21. Each of those models have slight differences like Quarz-Filter, Noise balancing system, tube 12A6 instead of 6F6 etc. They were mainly used for airbore and army purposes, later often found in HAM radio stations. There was also a confirmed production run in France after WW2. See also the "General page for BC-312".
