Digital to Analog Conversion Unit


ARD25

AOR has created an APCO25 digital decoder for use
with receivers that have a 10.7 MHz IF output!

It's true! Now you can receive standard (unencrypted) APCO Project 25 digital signals using an ordinary analog 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 your analog 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 analog signals pass through
  • Data output through RS 232C serial port
Receivers that 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 analog output through the ARD25. It will automatically recognize analog signals and pass them to the ARD25 internal speaker or to an external station speaker.

Some words of caution - 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 analog. The ARD25 does not add trunking capabilities to your receiver. Some jurisdictions may limit the use of devices such as the ARD25.
