The Maxon SD-670D Series of radios are durable, reliable and designed to meet the needs for a variety of wireless applications in either Digital or Analog mode. Digital uses AMBE3000 vocoder chip with AMBE+2 voice compression algorithm. The modules incorporate the most requested mechanical footprint and BNC antenna connection. Transmit power settings between two, five, and ten watts provide the power needed on any job and the LED indicator gives instant on-sight status of the radio’s operation. Combine that with low current drain and fast transmitter/receiver attack times for operation in the harshest of system demands. The die cast aluminum cabinet/lid provides resistance to RF interference; and gives exceptional environmental durability in the most extreme conditions.
