DV14307.03 Issue 06 February 2021 Transceivers 6200 Series 15
1.2 Purpose of Equipment
The 6200 series are a modern family of communication equipment.
Features:
• The sensitive receiver obeys the most recent requirements of ED-23C.
o It includes the ability to work in the offset-carrier (climax) operation in 25 kHz and
8.33 kHz channel spacing.
• The devices are for voice communication between aircraft or between aircraft and ground.
The devices use the VHF-band between 118.000...136.9916 MHz respectively
136.9750 MHz with a selectable channel spacing of 8.33 or 25 kHz.
• High efficiency transmitter delivers more than 10 W modulated, or un-modulated,
output power at 28 V supply voltage, or 6 W at 12 V supply voltage.
• The devices are made for applications where low power consumption is required e.g. for
gliders and leisure aircraft and balloons.
• The devices can operate from standard 14 VDC and 28 VDC installations and from
12 VDC or 24 VDC batteries.
• The receiver includes SCAN (dual watch) mode. This is for monitoring of two different
VHF frequency channels at the same time while the communication on the active
frequency.
• The squelch function prevents unwanted audio noise.
• The AUX audio input for connection of additional audio devices like navigation receiver,
warning-tone generator, or MP3 music player.
• The tandem function for a synchronized operation of two controllers.
• The intercom function is for voice communication between aircraft crew and passengers.
• The extended built-in intercom can work as:
o 4-way intercom with isolation mode – passengers could continue conversation or listen
to the music from a MP3 player at the same time while pilots talk through intercom or
communicate with the tower.
o 2-way intercom for tandem operation – pilot and co-pilot have different controllers and
can control their individual audio parameters, like volume or VOX. This mode is
preferred for training due to full synchronization of LCD contents.
• The devices have a non-volatile memory for the storage of:
o 99 channels for storage of VHF frequencies with customized labels.
o 9 recently selected VHF frequencies.
1.3 General Notices
The word "frequency" is also used in the sense of "channel name", as defined in EUROCAE,
document ED 23C chapter 1.3.2, Volume II.
In this document the word "memory channel" or "channel" is also used in the sense of a memory
position identified by a channel number, where a frequency may be stored for later use.
