OPERATION
After all connections are made, rotate the SQUELCH
knob fully counter-clockwise.
Turn the VOLUME
knob about one-half turn to apply power
to the
transceiver. If the transceiver is inoperative, check
to determine if the pilot lamps which illuminate the
meter and channel
indicators
are lighted.
If not,
recheck the power cord connections and fuse. Ad-
just the VOLUME
control until the desired listen-
ing tevel is obtained. Select the desired channel by
rotating the CHANNEL
knob.
The SQUELCH
control should be advanced slowly
clockwise
until background
noise just disappears
when a signal is not received. Excessive SQUELCH
control
insertion
will mute
the receiver even
on
strong signals.
To transmit,
press the Push-To-Talk
switch and
speak into the microphone in a normal voice.
While the transceiver
is in the transmit mode,
a
red lamp located above the channel
selector will
glow indicating RF output.
Release the Push-To-Talk switch to receive.
HI/LOW Switch
The FT-2FB is provided with a HIGH/LOW switch
on the front panel to provide output power of either
10 watts or 1 watt. For short range communication,
the low power position should be used for minimum
current drain from the power source.
Meter Indicator
A meter is provided on the front panel to check the
transceiver performance.
In the transmission mode, the meter indicates rela-
tive transmitter
power
output,
and during oper-
ation in the receive mode, the meter indicates incom-
ing signal strength. With a 100uV incoming signal,
the meter will indicate 8 on the dial.
BURST
Switch
BURST
Switch is located on the rear of chassis.
In the ON position, a tone signal of approximately
1800 Hz is transmitted for a very short time at the
beginning of the transmission.
With the switch in
the OFF position, this signal is disabled.
Antenna
The FT-2FB
is designed for use with a 50 ohm
resonant antenna.
The antenna is the most critical
part of the transceiver installation. Communication
range is dependent on how well the antenna system
is installed and adjusted. A commercial 1/4 wave
antenna is readily available from most local sources.
The length of coax cable between the transceiver
and the antenna is not critical but the VSWR
of the
antenna (including cable) is important.
If the VSWR
is greater than 1.5:
1.0, the antenna must be ad-
justed for a low VSWR
to obtain maximum
per-
formance of the transceiver.
