Codan 7727C
In the 7515 & 7727 range of radios i have found that the early models have no letter designation, hence
"I" have given them the letter A.
My findings show the early models are a 6 channel where the later models B, C, TB are all 10 channel models, this also reflected in the
Service Manual.

The
type 7727-C is a 100 wafts PEP transceiver, physically small, low in weight
and ideal for both mobile and base (fixed) station installations where the
operator requires a high level of transmitter power output This latest ‘C
series transceiver is electrically identical to the now superseded B’ series
but new finish colours and front panel styling changes have been introduced to
match other transceivers in our product range such as type 7727-TB mobile
equipment.
A
Mute facility, operator selectable, effectively eliminates background
(atmospheric) noise in the absence of a signal. An impulse noise limiter, when
selected, virtually eliminates interference from ignition and other similar
sources during signal reception periods.
A digital selective cal! facility based on CCIR recommendation 493 (Geneva 1 972) may be internally fitted to the transceiver. This can provide both encode only or encode/decode capabilities. A separate product data sheet provides full details
A
receiver scanning facility is available as an option. This allows either
selective calling or voice signal scanning for up to 6 channels. When a signal
is received the scan cycle stops and a numerical display identifies the called
channel.
Broadband
block filtering design techniques in the transmitter output circuitry ensure
that the unit can be inter-changed between installations without technician
adjustment. The transceiver is produced and guaranteed for 12 months by an
Australian owned and operated company which remains committed to the design,
manufacture and marketing of HF 858 communications products Antennas
The
transceiver may be used with any 50 ohm antenna system.
For
mobile applications it is most frequently installed in conjunction with our
code 300 series multi-frequency (tapped) helical :hip antennas or with the
code 311 automatic frequency select multi-channel whip antenna.
For
fixed (base) applications it may be used with either conventional single
frequency wire dipole antennas in conjunction, there necessary, with our type
7101 automatic antenna selectors: alternatively, it
may be installed with our code 402 series broadband antenna systems for
multi-frequency working into a single antenna system.
The
transceiver may also be used with our type 7208 Mk2B manual or type 7403
preset antenna tuners and associated code 403 end-fed long wire antenna or
code 406 guyed whip antennas.
