AOR proudly brings a solution to a common problem the listening enthusiasts are
facing: There are less and less signals to listen to with a traditional analog receiver, as
digital communication slowly but surely is replacing analog communication.
where ARD300 comes in place!
ARD300 is a digital voice decoder to be connected to a radio receiver’s I.F output.
This powerful device offers many great features as follows:
Decodes popular amateur digital voice modes from Icom (D-Star), Alinco and
Decodes popular commercial digital voice modes dPMR
(*2) and NXDN(*3), as
well as APCO 25 (Phase 1, conventional mode) used by U.S military and
diplomatic services around the world. DMR (Tier 1 & 2) decoding has been
added since firmware 409C.
Compatible with AOR legacy receivers AR8600MK2, AR5000(A/+3)(*4) AR-ONE(*4) and newer AR2300, AR5001D, AR6000.
Even supports any other brand’s receiver(*4), featuring a 10.7MHz or
45.05MHz I.F output. (*5)
When connected to the receiver’s audio-out, its internal speaker can output
both the analog signals and the decoded digital voice.
*1 V/D mode only.
*2 dPMR446 and Tier 1 modes only.
*3 6.25kHz mode only.
*4 ARD300 needs to be powered by a (non supplied) external power source.
*5 Not all 3rd party receivers have been tested. Some receivers might be incompatible for
AOR support strictly limited to use with AOR receivers.
To obtain best possible results from your ARD300, we strongly recommend that you
read this manual before use and familiarize yourself with ARD300.
Every effort has been made to make this manual correct and up to date. Due to

Compatible AOR receivers
Compatibility with non-AOR receivers
ARD300 supports any other brand’s receiver featuring a 10.7MHz or 45.05MHz I.F
output, under following conditions:
-Minimum 10dB gain between receiver’s antenna input and IF output.
-Receiver step size should be set at 6.25kHz to avoid frequency mismatch.
-Tuned frequency should not be more distant than 1 kHz from received signal, for error
Not all 3rd party receivers have been tested. Some receivers might be incompatible for
The quality of the digital voice decoding does depend on the receiver’s sensitivity.
AOR support is limited to use with AOR receivers.
