Application
The transceivers of the
FSG 70-System
are fully transistorized VHF radios of
monoblock construction for two way voice communications within the extended
frequency range of 118.00 MHz to 136.975 MHz in 25 kHz increments (760 channels).
The equipment is well suited for reciprocating, turbopropeller or turbojet engine aircraft
as well as for helicopters with reciprocating or turbojet engines. The equipment comply
with applicable RTCA Performance Standards (observe national regulations).
Featuring small dimensions, low weight and extremely low current consumption, these
units are suitable in motorized gliders, gliders, balloons, Ultralights, homebuilts,
experimentals and as emergency back-up transceiver too.
Together with the W. Dittel GmbH carrying cases the transceivers of the
FSG 70-
SYSTEM
can be used as portable, mobile and fixed base ground stations. The excellent
suitability of the units to be powered by batteries should be emphasized. Special
modes like Intercom, AF-External Input, storage of VHF-frequencies etc. are possible
without any other additional equipment (depending on type of unit).
The LC-frequency display can be illuminated.
The transceivers comply with the Performance Standards of RTCA- and EUROCAE-
regulations. Additionally they comply with the regulations for groundstations.
