Abstract : The report covers the development and fabrication of two engineering model stabilized master oscillator (SMO) systems to be used ultimately at FAA radio communications transmitter and receiver stations to control the frequencies of all the VHF and UHF communication transmitters and receivers in a station. The SMO system allows each transmitter and each receiver to operate on any assigned channel within its frequency range without the necessity of stocking a large number of crystals. Each channel frequency is derived from a common, highly stabilized reference source. A block diagram of the SMO system developed is shown. The system consists of one master reference oscillator system which furnishes the basic system reference frequency and ten slave oscillators which furnish outputs in ranges and increments as prescribed in the FAA SMO specification. All the slave oscillator outputs are phase locked to the reference frequency by means of a DIGITAL technique (DIGISMO) as described in Temco Electronics Proposal R24-406. (Author)
