Features:
No transceiver modifications needed.
The ARD9000 uses the same audio frequencies (300Hz~2500Hz) as microphone
audio to modulate the voice signal. This allows you to use an analog radio as a
digital voice radio.
Works on Single Side Band (SSB) mode.
The Automatic frequency clarifier function adjusts frequency offsets automatically in
the SSB mode. (Approximately up to +/- 125Hz). Utilizes the OFDM (Multi Carrier
Modulation) circuit that is effective against Multi-path or Selective Fading.
Automatic digital receive
Automatic voice signal detector recognizes the received signal as analog or digital,
automatically switching to the appropriate mode.
Built-in high grade Vocoder (AMBE)
Utilizing high-grade digital voice compression delivers quality digital voice
communication.
Built-in FEC error correction
A powerful error correction circuit delivers stable and reliable communication.
Small and compact unit. Easy to operate.
Simply connect the ARD9000 between the microphone jack and microphone. No
complicated modifications necessary. Optional interface cable for most popular
transceivers are available or you can build your own connectors.
Wide range of operation voltages
Operates on 10 to 16V DC from an external power source.
Utilizes a uniquely designed high performance DSP engine.
Uses established G4GUO open protocol.
ARD9000 vs. ARD9800
You might already know our ARD9800 Multi-Mode and Digital Voice Interface. The
main differences between the ARD9000 and the ARD9800 is that the ARD9000 is a
VOICE ONLY modem. However, both models are fully compatible for voice use.
