Trandmitter Drive. This euqipment generates a signal at
constant amplitude to drive the CARFAX transmitter. The
drive can be switched automatically from a constant
frequency (usually 526.5kHz) to a signal with three fixed
types of frequency modulation (125Hz and 200Hz tones and
bi-f.s.k.). The modulation is performed digitally. Power
requirements mains (240V, 50Hz). BMM 4U chassis. Sub-
units UN23/1ll, PS2/244, GE7/8, C09/5 and MD3/15. RD 1978.
