Gates 1950 Communications Catalog - Radiotelephone and radiotelegraph transmitters for 2 to 22 MHz. The telegraph transmitters can do 600 WPM. The radiotelephone transmitters are available as communications or broadcast models. The broadcast models include a modulation reactor. The communications transmitters run the final RF amplifier through the modulation transformer secondary.
This catalog also includes VHF FM transmitters (150 - 175 MHz) for short range point to point communications.
The catalog also contains communications receivers that cover 540kHz to 43MHz.
- Gates 1950 Speech Input Equipment Catalog - Audio consoles for AM, FM, and TV stations. Also listed are speakers, communications receivers, rack cabinets, patch panels, limiting amplifiers and other amplifiers, transcription equipment, tape recording equipment, disc recording equipment, line equalizers, microphones, attenuators, accessories, test equipment, price list, etc.
Another interesting product is a "telephone dial" driven remote line selector. The user dials the remote broadcast line to be used, and a remote stepper switch selects the appropriate remote broadcast telephone line.
- Gates 1950 Transmitter Catalog - AM transmitters, modulation monitors, frequency monitors, antenna couplers (tuning networks), directional antenna phasors.
