Batt Material Metal case Shape Portable set > 8 inch (also usable without mains) Dimensions (WHD) 10 x 13.7 x 9.25 inch / 254 x 348 x 235 mm Notes Precision heterodyne frequency meter designed to measure or radiate radio-frequency impulses between 125 kHz and 20 MHz. Portable, self-contained, used mainly to calibrate field radio receivers and transmitters by direct comparison with the crystal-calibrated variable frequency oscillator of the instrument. Frequency readings provided by a calibration book. Contained 1 MHz crystal oscillator and variable frequency oscillator operating in two switched ranges: 125 to 250 kHz and 2 to 4 MHz. The 2nd, 4th and 8th harmonics of the low-frequency range were used to cover 250 kHz to 2 MHz, while the 2nd, 4th and 5th harmonics of the high-frequency range were used to cover 4 MHz to 20 MHz. Supplied with aluminum-alloy cabinet. Required six BA-2 batteries (22.5V each), four BA-23 batteries (1.5V each) and HS-30 headset. P-18 or P-20 headsets may also be used. Early models of BC-221-N (Ser. Nos. 1 thru 3800) differ from later models (Ser. Nos. 3801 and up). The later models of BC-221-N are exactly alike electrically to the model BC-221-AA.
