● 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.
