Features:
No transceiver modifications needed.
The ARD9000MK2 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 drift 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,
quickly switching to the appropriate mode.
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.
Small and compact unit. Easy to operate.
Simply connect the ARD9000MK2 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.
Wide range of operation voltages
Operates on 11 to 16V DC from an external power source.
Utilizes a uniquely designed high performance DSP engine.
Uses established G4GUO open protocol.
The use of an open digital protocol means use of the ARD9000MK2 is permitted
on US Amateur Radio Bands (non-USA users should check applicable
regulations.)
ARD9000MK2 vs. ARD9800
You may already be familiar with our ARD9800 Multi-Mode and Digital Voice
Interface. The main difference between the ARD9000MK2 and the ARD9800 is
that the ARD9000MK2 is a VOICE ONLY modem. However, both models are fully
compatible for voice use.
Caution: Signal conditions vary greatly, as such; no warranty can be made on how the
ARD9000MK2 will perform in every circumstance.
