Features:
Digital voice communications using existing analog 2 way radios.
The ARD9800 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 transceiv er.
Digital voice communications in the 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 OD FM (Multi Carrier Modulation) circuit that is ef fective
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 (SSTV) -- Optional memory module (VM 9800) required
Built-in video capture function (NTSC). Compresses the signal into our original adaptive JPEG format.
Send and receive images (similar to analog slow scan TV) in the Digital mode. Built-in video output
connector (NTSC) allows view ing the picture on an external monitor.
Built–in high grade Vocoder (AM BE)
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.
Data communications on the HF band
Data communication is possible on the HF (High frequency) bands at no extra cost. (Speed may be
limited by regulations in certain jurisdictions.)
Small and compact unit. Easy to operate.
Simply connect the ARD9800 to the microphone jack. No complicated or risky radio modifications are
necessary .
Utilizes a uniquely designed high performance DSP (Digital Signal Processor) engine
Battery operation for field use.

Level Adjustment
Microphone Level
The microphone level has been properly adjusted at the factory with the provided microphone.
Therefore, no further adjustment is needed for normal operation.
If you wish to use your own microphone rather than the included one, you w ill need to wire your
microphone connector to match the pins of the ARD9800, and then adjust the microphone level as
described in the following steps:
17
1. Connect your microphone to the Microphone connector of the ARD9800.
2. Turn the [LEV] knob fully counterclockw ise.
3. Press and hold the PTT switch of the microphone, and speak into microphone normally .
4. Slowly turn the [LEV] clockwise until the [OVER] LED flashes occasionally , w ith the peaks of
your voice signal.
Radio Input Level
Perform the following steps to adjust the radio input level of your radio equipment:
1. Connect the microphone to the ARD9800, and then connect the ARD9800 to your radio
equipment. Finally , Connect the ARD9800 to a power supply .
2. Turn the output level adjustment on the bottom of the ARD9800 fully counterclockwise. Turn
the power on to the ARD9800. T urn the power on to your radio equipment.
3. Set the mode switch to the Digital mode [10101].
4. Press the [PTT] switch to transmit from the radio equipment.
5. Adjust the microphone gain of the radio equipment until the ALC function just activates.
6. If the microphone gain is too low, readjust the output lev el on the bottom of the ARD9800.

adjust the audio balance, perform the following steps:
If the output level of analog voice and digital voice are not equal, an adjustment can be made. T o
1. First, set the proper microphone level in the digital voice mode.
2. Turn off the pow er to the ARD9800. Press and hold the TX switch then turn the pow er back
on. The MODE LED should be blinking orange, indicating the ARD9800 is in the
microphone balance adjustment mode.
3. Hold ing the PTT s witch, and while speakin g into the m icrophone, adj ust the mic rophone
level.
4. After the adjustment is completed, push the TX switch to save the new setting. The ST A LED
will light to indicate the setting process is completed.
5. T o complete the operation, turn the power of the ARD9800 off, and then turn back it on.

Operations
Note: All adjustments must be properly performed before operation.
Voice Communication
Y our ARD9800 is capable of Digital V oice Communications and Analog Voice C ommunication.
In the receive mode, the ARD9800 will automatically recognize the type of communication, and set the
appropriate operation mode.
In the transmit mode, the operation mode can be selected by using the front Mode switch.
Digital Voice Communication
Set the mode switch [10101 - ~] upward to the digital mode position. [10101]
Press and hold the PTT switch of the microphone. The ST A (Status) LED w ill flash for about 0ne (1)
second while sending a data header signal.
When the LED stops flashing, speak into the microphone normally.

At the receive side, the data will be automatically decoded and displayed on the PC screen.
If the [ALF] command is set ON, the LF (line feed) code will be added at the end of received
data.
20
Digital Image Communication
Note: An optional memory module is required to use this function.
Receive
When valid digital image data is received, it will be decoded and output as a video image from the
VIDEO OUT connector .
If received data is missing during a transmission, that portion will be displayed as invalid (like noise).
Transmit
When pin - 4 of the microphone connector is grounded, the ARD9800 starts sending the image.
Note: When the Video Through Function is activated (A VT command is ON), pressing the T X switch
will enable output of the video signal connected to the Video Input to also be sent to the video
output, so that you can monitor the video image. Press the TX switch again to capture the
image and then transmit it through the radio equipment.
When the Video Through Function is de-activated (AVT command is OFF), pressing the TX
switch will automatically capture the video image and then transmit it through the radio
equipment.
A Progress indicator will display on the monitor during image transmission.
