SPECIFICATION

 
 

 

The HF-90 is a rugged all-purpose HF SSB transceiver, designed for manpack, portable, vehicle and fixed base station applications. It is an extremely compact and light weight unit, featuring only essential controls to ensure ease of operation. The HF-90 has been designed with the user in mind. Not only is it simple to operate, but it is also priced competitively to suit both commercial and military requirements. Furthermore, it is value-engineered to ensure low cost of ownership over the long term.

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. The unit can operate at a selected power level of up to 50 Watt, whilst achieving low battery consumption. It is also extremely reliable due to the advanced SMD manufacturing process used and overall design efficiency.

The specifications of the HF-90 will enable reliable communications up to distances of 3,000km*. In addition, the transceiver incorpo-rates superior signal handling capability which ensures excellent reception even in the most crowded radio environments.

In short, this revolutionary new transceiver incorporates the very latest in RF design technology, making the HF-90 the most compact, versatile, high performance HF SSB transceiver available on the market today.

Q-MAC Electronics has designed the HF-90 Transceiver so that it is simple to operate, incorporating only essential controls. However, an advanced option incorporating additional features is also available. The differences between the standard and advanced model are outlined below.

STANDARD MODEL

The standard HF-90 incorporates facilities as follows:

  • 2-30 MHz frequency coverage
  • 50 Watt PEP power output
  • 12V or 24V operating voltage
  • 255 programable channels
  • USB/LSB toggle switch
  • Tune function
  • Clarifier
  • 6 digit LED display

(with the exception of field programming and frequency hopping facilities). PC programming of the standard model is possible, using a simple Windows based PC software package, together with a programming cable which plugs into the HF-90 microphone connector (providing an RS-232 link). Note that the standard model is fully data capable. A compact speaker microphone is provided with this model, along with the appropriate DC power cable.

ADVANCED MODEL

The advanced HF-90 includes all features in the standard model, plus Selcall (Selective Calling) facilities, field programming (I) & (FH) and frequency hopping (optional) (FH). Selcall is a very effective digital calling system which allows each set to be designated with its own 4-digit ID. The Selcall format used in the HF-90 is the Australian Standard (based on CCIR International Standard 493-4), which is fully compatible with other Australian brands. Other Selcall based facilities offered include Telcall (allowing the HF-90 to subscribe to telephone interconnect systems) and Beacon Call (which provides a very timely and accurate measure of frequency suitability).

Selcall ID may be programmed in the field for all versions (including the Australian Version). Additional parameters which can be field programmed (I) & (FH) include power output, auto-tune setting, channel/frequency selection, Selcall setting, scan setting and mode setting. Frequency hopping parameters which can be field programmed (FH) include hop configuration, Smart Hopping setting and hop code.

Note that Selcall and field programming facilities require DTMF keypad entry. Therefore a DTMF microphone/handset is supplied with the advanced model, along with the appropriate DC power cable.

CONSTRUCTION AND SERVICES FEATURES

Q-MAC Electronics has designed the HF-90 so that it will adapt to multiple configurations. Its compact size, light weight and low battery consumption make it ideal for portable and man-pack applications. Its maximum power output of 50 Watt and full frequency coverage also make it suited to vehicle and base station configurations. In addition, the HF-90 has a DC supply voltage from 10-28 Volt, accommodating a variety of batteries and AC power supplies. The high voltage capability is a significant advantage for military and heavy vehicle installations. A full range of accessories is offered by Q-MAC Electronics to support the multiple configurations of the HF-90.

The transceiver is extremely rugged in its construction. The exterior case is made from a tough anodised aluminium extrusion, and all connectors and controls are fully protected by the rear heatsink and stainless steel handles on the front panel. The LED display is very robust, providing high resistance to physical impact.

The HF-90 is well protected against harsh environments, displaying a high tolerance to extreme temperatures, humidity and dust levels, plus resistance to water ingress. Product reliability is also enhanced as a result of surface mount technology used and simplicity of design (low component count). As a result of these factors the MTBF (mean time between failures) figure for the HF-90 is significantly improved.

The unit incorporates a BITE (built-in test equipment) function, which allows identification of possible faults, to a board or sub-unit level. Accurate fault location is further enabled by the provision of test points on IDC pin headers. If a fault is identified the unit is extremely simple to service. All internal PCBs can be accessed and probed without the need for special tools or jigs. In addition, the PCBs connect together directly so that there is no requirement for any looms or de-soldering of joints when exchanging boards. Furthermore, the low component count in the HF-90 means that the requirement to carry spares inventory is reduced.

The HF-90 is designed so that it is simple and economical to service. In addition, a comprehensive 3 year warranty and module exchange program offer further support for dealers and end users.
