AOR ARD9900 Multimode and Digital Voice Interface
Use an analog transceiver to send
encrypted digital voice, data or image
communications in one easy step!
Plus, maintain analog capabilities.
Encryption so powerful, it’s designed for use by law
enforcement and government professionals. The ARD9900
is a breakthrough in communications technology. By
simply connecting the ARD9900 to a pair of analog
transceivers, it is possible to send and receive clear,
reliable digital communications with encryption.
FOR PROFESSIONAL USE ONLY

●
Digital voice communications using existing
analog 2way radios.
The ARD9900 uses the same audio frequencies (300
Hz ~ 2500 Hz) as microphone audio to modulate the
voice signal. This allows you to use an analog radio
as a digital voice radio with or without encryption.
●
Works on Single Side Band (SSB) mode.
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 digital receive
Automatic voice signal detector recognizes the
received signal as analog or digital, automatically
switching to the appropriate mode.
●
Digital Slow Scan TV
Built-in video capture function (NTSC). Compresses
the signal into AOR’s original adaptive JPEG. Send
and receive images (similar to analog slow scan TV)
in the digital mode. Built-in video output connector
(NTSC) allows viewing the picture on an external
monitor.
●
Built-in high grade Vocoder (AMBE)
Utilizing high-grade digital voice compression
delivers quality digital voice communications.
●
Built-in FEC error correction
A powerful error correction circuit delivers
stable and reliable communications.
●
High speed data communications
on the HF band
High-speed (3600bps) data communication is
possible on the HF (High Frequency) bands.
(Speed may be limited by regulations in
certain jurisdictions.)
●
Small and compact unit. Easy to operate.
Simply connect the ARD9900 to the microphone jack
and speaker output. No complicated modifications
necessary.
●
Wide range of operating voltages
Operates on10 to 16 V DC from an external power
source. 6 V DC operation is also possible by
changing an internal jumper setting. Low power
consumption (Approximately 160 mA at 12 V DC)
●
Utilizes a uniquely designed high performance
DSP engine
Available only to authorized users. Documentation required.
No transceiver
modifications are necessary!
