EXPO Bush Ranger Owner's Manual
DELUXE 18CHANNEL
SSB/AM CB TRANSCEIVER
OWNER'S GUIDE
General Description
The Bush Ranger is a combination transmitter and receiver designed for
use in the Australian 27 MHz Citizens radio service. It is designed to meet
the Postal and Telecommunications Department requirements, RB249,
applicable to equipment in this service, and is not to be used for any
other purpose. P and T Form RB14 defines operation in this service and
the licensee is required to read and understand these regulations prior
to operating a CB transceiver.
A station license must be applied for by submitting a properly completed
Station License Application, Form RB13, as directed.
This unit will provide efficient and reliable radio communication in its
intended application if installed and operated in accordance with instructions contained herein.
Features
This transceiver is an advanced solid-state 2-way CB radio designed pri-
marily for mobile operation. It employs the very latest technology to
provide 18 transmit and receive channels in the 27 MHz band by means
of digital frequency synthesis with Phase Lock Loop [PLL] circuitry.
The transceiver can be operated over 18 channels in the conventional AM
mode or in suppressed carrier single sideband mode using either the
18 upper or 18 lower sideband channels, as desired. This not only triples
the effective number of operating channels from 18 to 54, but also
increases the effective range of transmission because all legal power is
concentrated in one sideband to provide 100% talk power. On receive,
the single sideband mode offers greatly improved sensitivity and selectivity;
this also contributes to an effective increase in operating range.
This transceiver also includes many features which will provide greater
operating convenience and assure optimum communications under a
wide range of conditions.
•
3-Position Mode Switch — selects AM, LSB and USB.
•
Illuminated Meter — indicates S units and RF Power Output.
•
Clarifier for fine-tuning on receive.
•
Variable Squelch Control.
•
Switchable RF Noise Blanker and Automatic Noise Limiter for effective
reduction of noise interference.
•
RF Gain Control.
•
Illuminated Channel Indicator.
•
Built-in Ceramic Filter provides razor-sharp selectivity — helps prevent
adjacent channel interference.
•
Provision for PA operation with volume control.
•
External Speaker Jack.
•
Push-to-talk dynamic mic with coiled cord and 5-pin DIN type plug.
•
Floating type chassis for negative or positive ground operation without
switching.

Operating Controls and Features
[1]
Clarifier:
Permits slight adjustment of receiver tuning. Used for clarity
on SSB reception and fine tuning of stations on AM reception.
[2]
Volume/On-Off:
Varies the sound output from the speaker. Also incorporates
an on-off power switch at the extreme counter-clockwise
position.
[3]
Squelch Control:
This control is used to eliminate any annoying background
noise when no signals are present. The degree of sensitivity
to incoming signals is adjustable. When the Squelch control
is rotated to the fully clockwise position, it provides maximum squelch, in the fully counter-clockwise position it
provides minimum squelch.
[4]
Mode Switch:
Selects mode of operation — lower sideband, upper sideband
or standard AM.
[5]
Channel Selector:
Rotary switch selects one of 18 channels for transmit and
receive operation.
[6]
ANL Switch:
Activates automatic noise limiter for reduction of atmospheric
noises.
[7]
RF Gain Control:
Used as gain control when receiving SSB signals, normally set
to maximum when receiving AM.
[8]
CB-PA Switch:
Used to switch unit to CB or PA mode.
[9]
NB Switch:
NB position selects special RF noise silencing circuit to
combat ignition noise.
[10]
Meter:
Illuminated meter indicates relative incoming signal strength
when receiving and relative RF power output when transmit-
ting.
[11 Microphone Socket:
5-pin DIN socket for attachment of push-to-talk microphone
[supplied].
