  • Notes

  • The VFO, model 666, is completely self-contained, including power supply and is calibrated for the six meter amateur band. RF output from the VFO is on the fundamental frequencies between 8333 and 9000 kHz (original KC) requiring suitable multiplier stages in the transmitter to obtain six meter output. Full 170 degree bandspread of the tuning dial is incorporated for operating convenience. Among the various features is the CALIBRATE switch on the front panel of the VFO. The switch allows the operator to energize the VFO independently of the transmitter in order to "zero beat" a received signal.

    The power supply uses two cascaded selenium rectifiers.
