ARD25 -
APCO25 Digital to Analogue Conversion Unit
AOR has
created an APCO25 digital decoder for use with
receivers which have a 10.7 MHz IF output!
Now you can receive standard
(unencrypted) APCO Project 25 digital signals using an ordinary analogue
receiver that has a 10.7 MHz IF output. The ARD25 processes the 10.7 MHz
signal, converts the digital transmission and sends it to the internal
speaker, or your station speaker. Simply connect the ARD25 and begin
listening to APCO 25 digital signals which your analogue receiver could
not previously process.
-
Easy to connect - easy to operate
-
Add "new life" to your
existing receiver
-
Compact size
-
No receiver modifications needed
-
Lets analogue signals pass through
-
Data output through RS 232C serial
port
Receivers which can use the ARD25
include the AOR AR-ONE, the AR8600 series and AR5000 series, as well as
other receivers and monitors that have a 10.7 MHz IF output port.
Many high quality receivers were "left behind" when some public
agencies began to use APCO Project 25 digital modulation. If your receiver
has a 10.7 MHz output port, the ARD25 can translate those digital signals
to intelligible audio. In addition, you can also channel your receiver's analogue
output through the ARD25. It will automatically recognise analogue signals
and pass them to the ARD25 internal speaker or to an external station
speaker.
Three modes are supported:
-
APCO25 conventional analogue demodulation,
no trunking
-
ASTRO25 analogue 3600bps
-
Digital 9600bps
Note: The ARD25 is not effective on systems that use
encryption or digital modulation other than APCO Project 25. It cannot
translate signals from receivers that do not have a 10.7 MHz IF output, as
the full channel bandwidth is needed to convert the signal from digital to
analogue. The ARD25 does not add trunking capabilities to your receiver,
it demodulates only! It will not decode other types of demodulation
such as GSM phones or TETRA / TETRAPOL.
