Grintek Ewation has established itself as an Electronic Warfare systems house manufacturing state-of-the-art products and systems. It prides itself in its leading edge range of wide band receivers and direction finders in both HF and V/UHF. GEW's product suite extends further to also include antennas and recorders. The product suite is manufactured under the MRCM trademark. www.mrcm.net
HF and V/UHF Wide band receivers
MRR8000
GEW produces a whole range of wide band receivers, including the MRR8000, MRS30 and the MRS3000. The MRR8000 is a new generation wide band HF receiver based on direct sampling of the HF band and is fully integrated with a wide band recorder function and digital demodulation. The MRR8000 comes in a HF or a V/UHF version.
The unit may be used in a stand-alone configuration, or as part of a larger system, by making use of its advanced software and interfacing features. An array of companion products can be used to integrate a powerful monitoring system using the IFS software architecture.
The MRR8000 can be used in conjunction with MRD Wide band Direction Finders, MRWA8000 Offline Analysis software, or an external analysis and classification system.

MRS30 and MRS3000
Meeting the challenge of the modern frequency agile and time-varying HF & V/UHF signals scenario, the MRCM MRS wide band receiver series utilises the latest technology to achieve outstanding scanning performance and high detection sensitivity.
High dynamic range circuitry, Digital Signal Processing and sophisticated man-machine interface graphics combine in a cutting edge solution to modern HF & V/UHF ESM requirements.
Some of the applications of the MRS30 and MRS3000 include:
- Spectrum Surveillance to identify new transmissions anywhere in the specific frequency range
- Stand-alone or integrated in system
- Scanning receiver for tasking handoff receivers in a system
- Front end for jamming systems
- Frequency monitoring and management systems
- Search Task with slaved narrow band DF equipment
