The VHF-90M Military transceiver is specifically designed for tactical military applications. The VHF-90M complies with military environment standards and is a extremely compact and light weight unit, featuring only essential controls to ensure ease of operation.
The VHF-90M transceiver is from the family of tactical transceivers manufactured by Q-MAC Electronics which are field proven in over 105 countries, on every continent and in all conditions, ranging from the climate extremes of Antarctica to the African Sahara.
The radio is available with a secure, jam-resistant ECCM Frequency Hopping option and Digital Encryption. The Frequency Hopping option does not rely on jammable GPS signals for synchronization. Radio frequency design takes into account the hostile electromagnetic environment of the battle field and achieves excellent ECM resistance.
The VHF-90M uses embedded software executed by a low current, high speed DSP core engine.
Speech coding and all frequency hopping and encryption functions are processed by the DSP under the control of a host microprocessor.
The same transceiver is used on Manpack, Mobile and Base Station roles which benefits users with reduced spares inventory, simpler training programs and thus faster deployment.
Radio service personnel will appreciate the solid construction and ease of maintenance of the VHF-90M. Only 4 fasteners provide access to 3 internal modules for exchange in less than 4 minutes.
A radio signals officer will appreciate the ease of use with only essential controls on the front panel. Advanced programming functionality is available in protected sub-menus.
The VHF-90M can be either field or PC programmed.
The VHF-90M transceiver offers four modes of voice communication and three modes of data communication, allowing operators to adapt to the required conditions and sensitivity of information being transferred:
- Analogue Voice - Fixed Frequency
- Digital Encrypted Voice - Fixed Frequency
- Digital Encrypted Voice - Frequency Hopping
- Digital Encrypted Voice - Free Channel Search
- Digital Data - Fixed Frequency
- Digital Encrypted Data - Fixed Frequency
- Digital Encrypted Data - Frequency Hopping
Applications
SQUAD COMMUNICATION
In stand-alone configuration, Q-MAC's VHF-90M is ideal for squad level communication requirements. As an intra-squad radio, the VHF-90M can communicate reliably up to 1km with a short rubber whip antenna or tape whip for typical distances of 3km whilst communication between squads can be achieved with a collapsible 3m whip antenna for ranges up to 10km depending on terrain.
The VHF-90M transceiver is designed for use with either handset or headset. For most tactical military situations, integrated microphones and loudspeakers are ineffective. The high level of ambient noise means that loudspeakers either cannot be heard or can also be heard by the enemy, posing significant risk to the operator. VOX is also impractical as noise will spuriously trigger it.
BRIGADE COMMUNICATION
The VHF-90M is available in mobile and base station configurations which include the VDS-90M Docking Station and VHF-50M 50W Booster Amplifier.
The VDS-90M Docking Station provides convenient docking of the transceiver as well as the flexibility for dismounted use of the VHF-90M when not in the vehicle. The docking station can be installed in a range of vehicles including jeeps, patrol boats, troop carriers and tanks. The unit has fixing points for anti-vibration mounting and interconnection to combat net radio systems incorporating intercom harnesses. Auxiliary connectors are provided for connection to data terminals or combat workstations.
The VHF-50M 50W Booster Amplifier provides range extension and increased link reliability in conjunction with the external Q-MAC vehicle whip antenna system. In the event of failure, the VHF-50M has a pass-through mode to ensure continuous communication at lower power levels.
The VHF-90M transceiver, in combination with the VDS-90M Docking Station, VHF-50M Amplifier and an AC mains power supply, can be used in base station configuration with an efficient broadband bicone antenna.
