The development of the Q-MAC HF-90M Frequency Hopping Option represents a significant breakthrough in the field of military HF SSB communications. For the first time, military users have access to a product, which is affordable, yet offers a very high grade of voice security. This option builds on the Q-MAC HF-90 established reputation as the world’s smallest high specification HF SSB transceiver. The addition of the frequency hopping option makes the HF-90M a secure military grade ECCM HF SSB transceiver costing approximately one quarter of competing military transceivers. Deliveries of the HF-90M from Q-MAC are measured in weeks rather than several months typical for military equipment.
Military users will appreciate the solid construction and ease of use of Q-MAC transceivers. Only 4 fasteners providing access to 3 internal PCBs allow any modules to be exchanged in less than 4 minutes. All connectors are gold to gold and wiring looms have been eliminated. Emphasis in the design of the HF-90M has been placed on value engineering to ensure low cost of ownership over a long service life.
This is achieved by utilizing SMD components from generic multi-sourced families.
The Q-MAC HF-90M HF Military Tactical transceiver has been designed with the tactical military user in mind. Only essential controls are included on the front panel for normal operations. Advanced programming functionality is available in sub-menus. The Q-MAC HF-90M can be either field or PC programmed.
The transceiver has a quality, high specification design. It provides full frequency coverage from 2 - 30 MHz and has capacity for up to 255 programmed channels. In tactical frequencies the unit can operate at selected power levels up to 50 Watt, (which is the highest in the industry for Manpack configurations), whilst achieving the lowest battery consumption compared to other military transceivers due to use of SSB modulation. The Q-MAC HF-90M is extremely reliable due to the advanced SMD manufacturing process used and overall mechanical design efficiency.
The Q-MAC HF-90M Military Tactical HF transceiver is a state of the art communication device specifically designed for tactical military applications. The Q-MAC HF-90M is certified to MIL STD 810-F. It is an extremely compact and light weight unit, featuring only essential controls to ensure ease of operation. The radio is available with a secure, jam-resistant ECCM Frequency Hopping option. It is fully qualified to Mil-Std 810F for immersion, shock, vibration, dust and temperate rating specifications. The Q-MAC HF-90 HF transceivers are field proven in over 75 countries on every continent ranging from climate extremes in Antarctica to African Sahara.
The Q-MAC HF-90M hf military tactical transceiver utilises a robust radar-style front-end utilising 10GHz GaAsFETs. This results in a very high dynamic range, allowing weak signals to be resolved in the presence of multiple adjacent strong signals. This leads to excellent ECM resistance and costing performance.
This military radio is unique in its ability to interoperate with UN aid agencies and relief NGOs when deployed in a peace-keeping role. The CCIR 493-4 selective calling facility, which is standard issue on aid agency radios, is used to initiate radio traffic in fixed frequency mode. Where full security is required on a military net the user will revert to using frequency hopping (ECCM). In short, this revolutionary new transceiver incorporates the very latest in RF design technology, making the Q-MAC HF-90M the most compact, versatile, high performance HF SSB transceiver available in the military market today suitable for Manpack, Vehicle and Base Station applications.
