Receiver
Accessories
(Tape
Recorder,
WeatherFax
Demodulator,
etc.)
Connection
of
a tape recorder, WeatherFax demodulator,
or
other such receiver accessory
is
easily accomplished by using the DATA
jack's
DATA
OUT
(1200 bps) terminal (Pin
5)
and
Ground (Pin 2). The audio output is fixed at 100
mY,
with an impedance
of600
O.
CONNECTION
OF
HEADPHONES
The
FT
-1
OO's
extremely compact size does not permit inclusion
of
a headphone
jack.
Direct connection
of
40
or
SO headphones to the Speaker
jack,
however, could cause
hearing damage, due to the high level
of
audio output available at that jack.
To
connect headphones to the Speaker jack, build a small
attenuator circuit into a small adapter box.
Connect a
lOon
y,
W resistor
in
series with the headphone line, and
a
Ion
Y,W
resistor shunt to the shield (ground).
ADJUSTING THE FRONT
FEET
The
two
front feet
of
the transceiver allow the trans-
ceiver to be tilted upward for better viewing. Sim-
ply
fold both feet forward to raise the front
of
the
transceiver, and fold them back against the bottom
case
to
lower the front
of
the FT -100.
