Monitorscope YO-100

  • he Yaesu YO-100 is a station monitor scope that will allow you to monitor and adjust your transmitter for the cleanest signal possible. The YO-100 is compatible with virtually all transmitters and transceivers. The cabinet and front panel design of the YO-100 matches that of the FT-101B/277B and FT-201 series of Yaesu equipment. The features include a wide range of inputs for monitoring many different modes, such as SSB, CW and Digital. A built-in 1500 Hz and 1900 Hz tone generators greatly adds to the versatility of this station accessory. This two-tone generator produces the proper audio signals to perform a “trapezoidal” pattern for testing the linearity of a transmitter or amplifier.
    The specifications are as follows, for the vertical trace the sensitivity is 200 mV P-P/cm and the frequency response is 10Hz to 60MHz. For the horizontal trace the sensitivity is 300 mV/cm, the frequency response is 10Hz to 16kHz and the sweep frequency is 10 Hz to 10 kHz. The two-tone generator frequency is 1500 Hz and 1900 Hz which is Independently selectable by front panel controls and has an output level of 50 mV.
    The YO-100 uses 5 tubes in it’s circuit which are as follows, a 12BY7A as an Audio Frequency Amplifier, a 12BY7A as an I.F. Amplifier, a 12AT7 as a Clamp, a 3RP1A as the Cathode Ray Tube and a 6AL5 as a R.F. Detector.
