The developmen

13、t of the 940, utilising Barretts 900 series transceiver technology and military packaging has resulted in a realistically priced, fully featured portable/manpack transceiver that fills the void between limited function portables and full military specified manpacks. To provide the flexibility in dep

14、loyment that is vital for successful field operations, the Barrett 940 can be used in a number of configurations. In a manpack configuration the 940 is self- contained with a clip on battery pack and is fitted into a comfortable padded canvas backpack. In this configuration it can be supplied with a

15、 rapid deployment single wire end fed broadband with an efficiency that far exceeds that of the traditional whip antenna. For temporary base station or mobile operation, an optional power lead which includes a cigarette lighter type plug and clip leads, plugs into the front panel allowing operation

16、from a 12 volt DC source such a vehicle battery or AC mains power supplies. The BNC RF connector on the front of the transceiver can connect to tactical tuned dipole antenna, base station broadband antennas or manual tapped vehicle whips. An optional antenna tuner that clips on to the 940 and provid

17、es fully automatic tuning of a long wire antenna or an optional collapsible whip. The Barrett 940 can be field programmed by direct entry on the front panel of the transceiver or by using a personal computer connected to the RS-232 interface. A cloning facility is also available to enable programmin

18、g information to be copied from a master transceiver to other 940 transceivers An optional rugged lid with a carry handle that clips to the top of the transceiver provides extra protection from the elements whilst in transport and also provides storage for the microphone, power cable and antenna sys

19、tem. Optional features include selective call, considered essential for the efficient use of HF networks, Pagecall providing for the reception of 32 character paging messages and Telcall, allowing the user to make direct dial telephone calls via base stations equipped with Barrett 660 or 960 telepho

20、ne interconnect systems. Other standard features included in the Barrett 940 are Built in Test Equipment (BITE), two scan tables, battery condition monitor, VSWR and power displays and variable intensity display back lighting. Accessories include a transportable tactical tuned, end fed dipole antenna, an end fed, single wire, rapid deployment antenna,
