GEM NGDP-10 Digital Audio Data Packet Transmission System

The GEM NGDP-10 digital audio data packet transmitter is a fully commandable transmitter offering high levels of protection from interception.

The NGDP-10 data packet transmitter is suitable for most concealments, making it an indispensable intelligence gathering tool for undercover operations, available as a flat PCB transmitter or camouflaged in a car keyfob with rechargeable Li-Pol battery.

The NGDP-10 transmitter is fully remote controllable, enabling users to switch on/off or change the channel. Two operating modes allow choosing either one or multiple frequency transmission technology, thus increasing the reliability of transmission. While in stand-by mode the transmitter is passive and therefore can not be detected by RF spectrum analysers.

The 16 channel receiver with built-in SD card recorder offers all the necessary tools for an operation. Multiple NGDP-10 transmitters may be used with a single receiver.
