Wood & Douglas FM TV equipment
During the 1980's, Wood & Douglas produced a range of 1.3GHz FM TV equipment that gave many amateurs their first taste of microwave ATV operation.
The VIDIF was an FM TV demodulator board with an IF input of 50MHz. Separate boards were required for video de-emphasis and the sound sub-carrier.
