  • Anotaciones
  • Frequency Range: 27 to 39 mc. Type of tuning: Continuously variable, and detent selection of 3 preset frequencies. Channel Spacing 100 kc. Number of channels: 120.
    Receiver type: FM, single-conversion, super-heterodyne. Types of signals received: voice-modulated or tone. Method of calibration of tuning dial: built-in, 4.3 mc, crystal-controlled oscillator. Calibration frequencies: multiples of 4.3 mc.
    Accuracy of calibration: approximately ± 0.1 percent.
    External (emergency supply): 6.3 volt and 130 volt external dc supply.
    Antenna: portable whip antenna. Coaxial connector and binding post on front panel.
    Sensitivity: over 25 db signal plus noise-to noise ratio at 0.5 µv (microvolt), deviation ± 15 kc.
    RF oscillator range: 31.3 to 43.3 mc. Bandwidth: (6 db down) 85 kc ± 15 kc.
    Audio output impedances (each): 600 ohm, unbalanced. Squelch circuit: continuously variable mounted SQUELCH control adjusts squelch sensitivity to open on signals from approximately 0.3 µv to 80 µv.
    OFF position of control disables squelch circuit.
