DESCRIPTION
Your
CS-502
Tone
Transmitter is
the most
compact
full
power
hand
held single
channel tone
transmitter
presently available.
It
is
designed to operate with
any
existing tone receiver responding to
modulation
within
the 400-1000 cycle tone
range.
Tone frequency
is
approximately
?00
cycles, providing
maximum
per-
formance with the
CS-501
and
CS-503
Receivers.
Long
range
and
extended
battery
life is
obtained
from
standard
full
size batteries.
Transmitter
circuitry is
basically
a
crystal-controlled
vacuum tube
oscillator
doubling
into
a
power
amplifier
section which
feeds
the
antenna
circuit.
Output
fre-
quency
from
the
transmitter is in
the
2?
mc
"C"
band,
exact
frequency
being
determined
by
the crystal em-
ployed.
Doubler operation, together with the
MOPA
circuit,
provides minimum
drift with
maximum
output
and
frequency
stability.
Placing your hand on
the
antenna does
not affect
frequency
but merely
reduces
transmitter
output by
absorption.
The
CS-502
Trans-
mitter
meets
all
FCC
'3C" bald
requirements,
A
single
transistor Hartley oscillator is
used
to
supply
the
sine wave
audio
tone
(700 cps)
for grid
modulation
of
the
output
stage.
Due
to the LC
circuit
employed,
tone
frequency
is
stable
regardless
of
battery
voltage.
