AOR ARD9000 Digital Voice

The ARD9000 makes digital voice communications FUN & affordable. Now you can use your existing analogue transceiver to work digital voice on Amateur Radio bands without making any modifications to your transceiver.
No transceiver modifications needed.

The ARD9000 uses the same audio frequencies (300 Hz ~ 2500 Hz) as microphone audio to modulate the voice signal. This allows you to use an analogue radio as a digital voice radio.

The Automatic frequency clarifier function adjusts frequency drift automatically in the SSB mode. (Approximately up to +/- 125 Hz). Utilizes the OFDM (Multi Carrier Modulation) circuit that is effective against Multi-path or Selective Fading.

Automatic voice signal detector recognizes the received signal as analogue or digital, automatically switching to the appropriate mode.

Utilizing high-grade digital voice compression delivers quality digital voice communications.

A powerful error correction circuit delivers stable and reliable communications.

Simply connect the ARD9000 between the microphone jack and microphone. No complicated modifications necessary. Optional interface cables for most popular transceivers are available or you can build your own connectors.

Operates on 10 to 16 V DC from an external power source.

Utilizes a uniquely designed high performance DSP engine.

The use of open digital protocol means use of the ARD9000 is permitted on Amateur Radio bands (UK, USA, Japan and most countries are permitted)
