Are you trying to monitor a huge political protest? Look no further than DRT. Nicknamed “dirt boxes,” these devices can locate up to 10,000 targets and can process multiple analog and digital wireless devices all at the same time. They’re even capable of intercepting and recording digital voice data. The best thing about the devices is the fact that no one may ever know you’ve used one. Just be careful — if your targets do figure out you’ve used a DRT box, and you haven’t gotten a warrant, they may be able to convince a judge to throw out all the evidence you’ve collected on them after you used the device. You can mount DRT models like this one in an aircraft to fly over the crowd.

Capabilities

The DRT 1201C provides a compact, yet powerful, surveillance capability against a variety of analog and digital wireless standards. The DRT1201C can be configured to support DF, digital voice intercept/recording, supports target lists of up to 10,000 entries, and has a flexible tuner configuration which provides frequency coverage of all bands of interest. Up to four tuners can be incorporated in unit.

Limitations and Planning Factors

- Monitors up to 544+ half-duplex channels (32+ channels per WPM3). - Software configurable to process various wireless standards. - Processes multiple formats simultaneously. - DF option available. - Flexible tuner configuration provides frequency coverage of all bands of interest. - RFT3: Dual channel transceiver VHF/UHF coverage from 2-3000MHz; HF from 0.5 - 32 MHz - HFT1: High performance HF receiver from 0.2-30 MHz - MUT1: Microwave receiver from 0.2-8.5 GHz - FPGA based Wireless Processor, WPM3, enables wideband signal processing. Can also generate 32+ narrowband signals.
