8525
series
The 8525A transceiver ran from 1985 to about 1988, and was the first series of Synthesized transceiver built by Codan.
Channels
Up to 99 channels can be fitted in eprom.
Antennas
The
8525 series may be used with any 50 ohm antenna system.
For fixed station applications, the transceiver may be used a broadband antenna system, and will plug straight into a 9350 mobile Autotune.
Will also work with a 8558 Autotune, if interfaced with a 8551 interface control unit.
Selective
call
Digital
selective call facilities based on CCIR recommendation 493-1 (Kyoto, 1978) may
be fitted internally, or externally, to the transceiver to provide encode only
or encode-decode capabilities. Refer to the listed options.
If
the transceiver is required to operate with the externally connected selective
call unit type 8422 series, or controller type 8511, it must be fitted with
option PS to provide the correct interface facility.
Scanning
A
receiver scanning facility operating
on voice signal is provided as standard. This facility, which can be
programmed by the user, provides for a maximum of 15 selected channels to be
scanned in sequence over a 15 second period. If so required, a user can select
priority’ channels by programming the same channels more than once within
the 15 entry sequence.
When
selective call options SDE or SDEM are fitted a maximum of 6 selected channels
will be scanned. In this mode the transceiver will automatically acknowledge
that a call has been received by transmitting a ‘revertive’ signal back to
the sender.

Early model 8525A RF board VCO's have screw instead of solder lugs to seal cans. Note that this VCO board has the optional LSB crystal fitted (bottom R/H corner of photo).
Early remote heads (See A0261 in photo) had the Mic hard wired into the head, instead of 7pin socket.
