  • Page 3 RF Exposure Warning To ensure optimal transceiver performance and to avoid exposure to excessive electromagnetic fields, the antenna system must be installed according to the instructions provided. High voltages exist on the antenna during transmission and tuning. Do not touch the antenna during these activities. RF burns may result. Install the grounding system or counterpoise as directed to prevent RF burns from any metal part of the transceiver.

    BARRETT 4050 HF SDR TRANSCEIVER - APPENDICES Appendix 3 - Overview of HF Operation HF (High Frequency) is the radio spectrum with frequencies between 1.6 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,...

In each illustration the height of the ionosphere above the ground is shown. In both illustrations Station A communicates with Stations B, C and D. Propa- gation from Station A to B is by ground-wave.
  • Page 170 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 4050 Trans- ceiver, 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.
