Base Docking Station

Introduction

The PRC-2090 base docking station incorporates the PRC-2090 vehicle docking

station plus an AC Power supply module P/N 2090-06-01.

A MIL-STD high speed HF Modem (P/N 2090-04-10) with software to suit is also

available as an optional extra.

This section provides instructions for the installation of land based HF

communication equipment.

Most of the installation work can be performed by non-technical personnel if they

carefully follow the instructions given in this handbook. It is however recommended

that the completed installation be checked by a suitably qualified technician. In some

equipment configurations, technical adjustment is required for the equipment to

operate correctly.

Note:-Some equipment has specific instructions supplied with it. When this is the

case those instructions over-ride the general guidance of this handbook, and must

be followed in detail.

Unpacking and Inspection

When unpacking the transceiver, check the contents against the packing note

provided. Before discarding the carton, check that all accessories have been

removed and are not mislaid in the packing material. Inspect the equipment for any

transit damage. If damage has occurred notify your supplier immediately and gain

their advice on further action. Failure to do this could affect the warranty covering

the equipment.

Fixed Station Installations

Transceiver Position

The following should be considered when choosing a position for the transceiver.

Operating Convenience

The transceiver should be placed so that the operator is comfortable and any

facilities he may require are easily accessible.

Air Circulation

Most transceivers rely on air flow around cooling fins to dissipate heat generated by

the transmitter. The mounting position must allow free air flow around these fins.

Proximity of Transceiver to Antenna

When using RG-58 coaxial cable from the transceiver to the antenna a cable length

of no more than 30 metres is recommended. Should a run of more than 30 metres

be required it is recommended that a low loss coax such as RG-213 or RG-8 be used. It is recommended that the transceiver chassis is connected to ground using the bolt on the rear panel to stop pick-up of unwanted noise from local power supplies and electrical equipment. Power Supply All Barrett transceivers require a supply voltage of 13.8 VDC.
PAGE 3
Antenna The antenna is a most critical part of the complete radio installation. It must accept the output power from the transmitter, radiate that power with minimum loss and in the receive mode, accept weak signals for input to the receiver. Incorrect antenna installations will yield poor system performance and are often the cause of complaints of poor transceiver performance. A range of antennas is available from Barrett to suit most small fixed stations.
