    BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - INSTALLATION Marine Installations The Barrett 911 automatic antenna tuner is designed for use in land base station and maritime HF services. Primarily designed for operation with end-fed unbal- anced antennas such as whips and long wires, the tuner is built in a waterproof impact resistant, moulded ABS plastic enclosure.
  • Page 192 A directional watt-meter may be inserted in the coaxial transmission line between the transceiver and the tuner, if desired, although the internal tuner of the PRC-4090 transceiver is accurate. The tune mode on the transceiver is then activated (see page 107). Upon application of RF energy, the tuner should start to tune, indicated by the ‘clattering’...

  • Page 219: Appendix 3 - Overview Of Hf Operation

    BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER -APPENDICES Appendix 3 - Overview of HF Operation HF (High Frequency) is the radio spectrum with frequencies between 1.5 and 30 MHz. Within this radio spectrum an efficient form of transmitter modulation, SSB (Single Side Band), is used. This, combined with the use of the ionosphere - a layer of ionisation gases that resides between 100 and 700 km above the Earth’s surface, provides efficient, cost effective communications over short,...
  • Page 220 BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - APPENDICES Radio Wave Propagation The following illustrations show the characteristics of ground-wave and sky- wave propagation during day and night time. In each illustration the height of the ionosphere above the ground is shown.
  • Page 221 Generally speaking the greater the distance over which you want to communi- cate, the higher the frequency you should use. Beacon Call, a Selcall (Selective Call) function built into the Barrett PRC-4090 Transceiver, makes finding the correct frequency to use easy. A Beacon Call is based on the network of transceivers all having a selection of frequencies that will accommodate most ionospheric conditions.
  • Page 222 VHF or UHF transceivers. Failure to correctly install an HF/SSB system will greatly affect the communications quality you will obtain. Your local Barrett representative will be able to assist with your system config- uration and/or installation. HF Communications Compared with VHF or UHF Short Distance...

    BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER -APPENDICES Appendix 4 - BITE Test It is recommended that any accessories (ATU, linear amplifier, Dual Antenna Switch Unit, secondary control head, GPS etc.), auxiliary port connections and the antenna be disconnected from the SDS or manpack to get consistent BITE test results.
  • Page 224 BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - APPENDICES Analog to Digital Converter This test checks if the A/D converter for measuring the final stage voltage is accessible. A failed test indicates an issue with the I2C bus on the microboard, the pre amplifier board, a loose connector between the two transceiver halves or a defective A/D converter.
