Description: VFO Variable Frequency Oscillator
                                    1-1. GENERAL.
1-2, The VFO, Model 666, is made by WRL Electronics, Inc. of
Council Bluffs, Iowa. 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 8330 and 9000 KC requiring suitable multiplier
stages in the transmitter to obtain six meter output. Full
170° bandspread of the tuning dial is incorporated for
operating convenience.
1-⅛. The VFO, model 666, is housed in a distinctive cabinet
of modern design. Dimensions are 6-5/8" high, 7⅛11 long and
7" vide. Weight is approximately 7 pounds. 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. A new exclusive feature called VFO
BANDSPREAD permits very precise tuning of the VFO and
eliminates "overshoot" when "zero-beating" a specific
signal. RF output is obtained through a cable connected to
the rear chassis connector labeled OUTPUT. Length of this
cable should not exceed four feet. The VFO may be removed
from the cabinet for service and inspection by removing the
two top panel screws and the two rear chassis screws. Power
requirements are 115V AC,
50/60 cycles, 10 watts.
