  • Frequency range selectable oscillator for multichannel communication system
    Patent number: 4009451
    Abstract: To provide the required multiple channels for an aircraft communications system, a crystal controlled reference oscillator includes a tunable circuit for changing the base reference frequency provided by a crystal. The base reference frequency of the crystal controlled reference oscillator is pulled in frequency by changing the capacitance shunting the crystal. Two transistor switches change appropriate capacitors in series with the usual oscillator capacitor to obtain the capacitance values needed to pull the base reference frequency and thereby provide additional reference frequencies. The transistor switches are controlled by pilot actuated controls that operate a sliding display mark over a digital frequency indicator.
