Safety It is essential that the transceiver be mounted in a place where it cannot cause injury to the occupants of the vehicle in the event of a motor vehicle accident.
  • Page 109 BARRETT 4050 HF SDR TRANSCEIVER - INSTALLATION Air Circulation The 4050 relies on air flow around cooling fins to dissipate heat generated by the transmitter. The mounting position must allow free airflow around these fins. Obstruction The installation of a transceiver into a vehicle should not inhibit the normal use of the vehicle.

    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.
