The type 8727 is a 10 channel,
100
watts PEP transceiver designed for both mobile and fixed base station
installations.
With colour and styling based on the Internationally accepted 8525 series G9-chennel synthesised transceiver, the type 8727 has been created for users who need e simple-to-operate, no frill crystal controlled communications package Incorporating the latest concepts in design technology and manufacturing reliability.
The
type 8727 series comprises a front panel control transceiver which may be used
for either fixed base station or mobile operation, and an extended control
transceiver package which includes a transceiver fitted with a blank front
panel and the type 8730 control head. This can be used for vehicle trunk3
or boot.
mounted
applications as wells for fixed
station3
extended control installations Included as standard features of the
transceiver are an impulse noise limiter circuit to reduce interference from
vehicle Ignition and other similar sources of electrical noise. and a voice
operated mute facility which effectively eliminates background noise in the
absence of a signal The mute facility Is operator selected.
The
design provides for a number of options to
be
fitted — Including that of the Australian Royal Flying Doctor Service
emergency cell system — and is offered with a full range of supporting
hardware and accessories thus making the 8727 a versatile unit fitting a range
of communication applications The 8727 series Is developed and manufactured by
Codan, the largest Australian-owned manufacturer of HF SSB communications
equipment and one that has achieved world-wide recognition with exports to
some 90 counties.
Channels
Two
channels are factory fitted as standard.
Antennas
The
8727 transceiver may be used with any 50 ohm antenna system.
For
fixed station applications the transceiver may be used with broadband antenna
systems such as the code 402 or code 408 series for multi-frequency working
into a single antenna
Alternatively,
for limited channel operation, the transceiver may be used with the code 400-1
single frequency wire dipole antennas In conjunction with an antenna selector.
For
mobile use there area number of antenna types available to suit most operator
requirement Including the code 300 series multi-frequency tapped helical whip,
the code 311 automatic frequency select helical whip and the type 5550 series
automatic antenna tuning system.
AC power supply
For
those fixed stations where AC main is available there are alternative power
supplies for operation with the 8727.
The type 7113-B, designed to tickle charge a and-by lead acid battery as well as supply power to the transceiver, Incorporates a NC-BREAK facility which, on mains failure. automatically connects the battery to the transceiver without loss of operation. The mains voltage must be specified when ordering.
The
type 8540 has been specifically designed to operate with the 5727 and
therefore matches the transceiver In appearance and size, but It doss not
incorporate the automatic no-break facility. The power supply has been
designed to operate over the range of mains supply voltages and frequencies
used throughout the world.
