1.2 Purpose of this equipment
The Filser ATR 57 is a VHF Communication transceiver covering the
aeronautical radio frequency range from 118,00MHz to 136,975 MHz in
25 KHz increments with 720 channels.
The ATR 57 was designed that all operational requirements encountered in
VFR flying can be met. The Communication transceiver is designed as a
single block unit with 57mm diameter for instrument panel or consul
mounting. It is fastened by four (4mm) screws. All controls and indicating
displays are located on the front panel. The rear panel of the unit locates
the connector (sub D9) for connecting the aircraft wiring. The VHF
Antenna is connected to the BNC socket.
The volume and squelch level can be selected easily.
The Unit can store 9 VHF frequencies in the memory for faster access in
operation. The Filser ATR 57 also contains an intercom facility controlled
by a special feature VOX (Voice Operated X-mission). This is a voice
level controlled switch for the headset to turn off the background while no
speaking. For good VOX performance identical Microphones should be
used and a correct input level must be set.
Two Microphones and Two Headphones and an additional speaker can be
connected to the unit. For Intercom operation with a bad Microphone
selection an optional Intercom switch can be installed to turn off the
background manually.
