INTRODUCTION 1. INTRODUCTION1. INTRODUCTION 1. INTRODUCTION About this Guide The main purpose of this guide is to provide you, the HF-90 user, with all the information you require to ensure optimum performance from your HF-90 radio. The Guide explains in detail how to operate the HF-90 once it has been programmed by an authorised Q-MAC Representative. It also contains an Addendum concerning Field Programming, which is relevant only to international users (outside of Australia) who are licensed to program their own operating frequencies. The Guide also covers basic principals of installation by way of check-lists. It does not give comprehensive instructions on how to install the HF-90. We recommend that the installation of your HF-90 be carried out by a qualified Q-MAC Representative. This device complies with Part 90 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference.

UNDERSTANDING HF/SSB 2. UNDERSTANDING HF/SSB2. UNDERSTANDING HF/SSB 2. UNDERSTANDING HF/SSB What is HF/SSB? HF (High Frequency) is the section of the radio spectrum between 1.6 and 30 MHz. SSB (Single Sideband) is a form of radio modulation. HF/SSB combines the characteristics of HF frequencies with SSB modulation to provide very efficient, flexible and inexpensive communications. HF/SSB will enable short, medium and long range communications over flat, hilly or mountainous terrain - without the need for expensive re-transmission devices, such as the repeaters used in VHF (Very High Frequency) communications. Also, unlike satellite communications, there is no dependence on a service provider with all the associated ongoing costs. In many remote areas around the globe, and in certain conditions, HF/SSB is the only form of communication possible. 3 Section 2.1 HF-90 Operation & Installation Guide How does HF/SSB work? When HF/SSB radio waves are generated there are usually two components:- ƒ The ground-wave, which travels directly from the transmitting antenna to the receiving antenna following the contours of the earth, and ... ƒ The sky-wave, which travels upward and at…

* Subject to antenna configuration, frequency in use and environmental conditions. T he HF-90 is a rugged all-purpose HF SSB transceiver, designed for man-pack, 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 require- ments. 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 perform- ance HF SSB transceiver available on the market today. HF-90 COMPACT TRANSCEIVER CONTROLS & SOFTWARE FEATURES 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 the facilities indicated in the above illustrations (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. (A) Australian Version only (I) International Version only (FH) Frequency Hopping Version only Eight pin microphone connector (screw-in type). Incorporates RS-232 link. On/Off switch. Alarm key (A) . USB/LSB mode selection key (I) . Fixed/hopping mode selection key (FH) . Six digit LED display (7-segment). Volume control knob. Channel up/down scroll keys. Pressing both keys together enables access to PC Programming. Tune key. Allows continuous signal to be trans- mitted for tuning long wire antennas. Clarifier up/down scroll keys. Pressing both keys together enables access to field program- ming (I) & (FH) . Pressing both keys together enables channel erase facility. Pressing both keys together enables Rx signal strength meter. BNC antenna connector (bayonet type). Four pole DC connector. Incorporates ATU control and loudspeaker signal.
