Model CHT will convert any single frequency or band of frequencies between 108 MC. and 174 MC. down to the broadcast band or any other IF output. It is crystal-controlled and has a 0.5 uV sensitivity. Model CHT is transistorized and uses an internal battery or can be operated from a car battery with the Ameco BS-9 adapter. It will work into any broadcast band radio, including pocket transistorized sets. It can therefore be used for mobile or fixed operation. A switch allows the radio to operate normally or with the converter.
Model CHT-2 is the same as Model CHT except that it contains two crystals and an extra switch position. Model CHT-2 can therefore receive any two single frequencies or bands in the 108 to 174 Mc. range. The two frequencies or bands must be less than 4 MHz apart. Specify input and output frequencies.
