SPECIFICATION
INTRODUCTION
The VFO-820
is a solid state remote VFO which
matches the
Kenwood TS-820.
It is designed for use with the TS-820 on the
amateur bands between 1.8 and 30.0 MHz.
When connected to
the
transceiver,
the
VFO-820
allows
VFO
controlled
cross-channel
operation
(the use
of separate
frequencies
for
transmission
and reception).
All VFO
power,
signals, and switching
are supplied through a
single
interconnecting
cable.
A
build-in
RIT
circuit,
with
a
light-emitting-diode indicator, allows receiver incremental tuning
with the remote VFO.
Light-emitting-diodes
on the VFO
and transceiver show which
equipment
is controlling
operation.
All of the VFO
switching
functions are controlled by the VFO-820
The VFO-820
uses the same
high stability, low distortion VFO
circuit found in the TS-820.
