  • Notes
  • Radio Receiver BC-224-B:  Aircraft receiver covering medium - and shortwaves in six bands, 1,5-3 / 3-5 / 5-7,5 / 7,5-10,5 / 10,5-14 / 14-18 MHz, modes AM (A3) and CW (A1, with BFO) powered by 14 V DC from aircraft on-board power system.

    The successor of the original BC-224-A, the BC-224-B receiver was an improved construction with removable band switching coil assemblies, an improved dial and an improved dynamotor power supply.

    The included original power supply was the DM-24 dynamotor supply and the shock mount the matching FT-154-(*).

    Under contracts 17840-NY-39(1-5-39), 65-NY-40 (8-8-39) and 65-NY-40 (8-18-39), the RAC (Radio Corporation of America) produced around 1000 of these BC-224-B receivers beginning in 1938.

    The RCA produced the technically identical variant BC-224-C under contract 1780-NY-41.

    This was followed by the technically identical variant BC-224-D under contracts 64-PHILA-42 and 94-PHILA-42 also produced by the RCA.

    Based on U.S.Air Force receiver experience, improved models with added longwave / beacon band coverage (BC-224-E to -L suffixes) have been produced later, even more successful were the 28V DC versions of this receivers, the BC-348 receiver series.
