Preface
Dear Customer,
Thank you for purchasing this BECKER AVIONICS product. We are confident that our GT6201
VHF-Ground-Transceiver will meet your expectations.
GT6201 VHF Ground-Transceivers are a modern family of communication equipment that have
comprehensive capabilities and significantly extend the typical aeronautical transceivers. All
GT6201 VHF Ground-Transceivers variants are not approved for flight!
For airborne use the BECKER AR6201 series perfectly corresponds to the GT6201.
Despite its small size and weight GT6201 include inter alia:
•A sensitive receiver which meets the most recent requirements of ETSI EN 300 676.
•A receiver that includes SCAN (dual watch) mode which allows simultaneous monitoring of
two different VHF frequency channels without interrupting communication on the active
frequency.
•A high efficiency transmitter which delivers more than 10W modulated or un-modulated RF
output power at 28V supply voltage or 6W at 12V supply voltage. The general low power
consumption of the unit allows longer operation time from a back-up battery.
•Non-volatile frequency (channel) memory:
o99 VHF frequencies, stored in dedicated channels, can manually be labeled with up to
10 characters for easy identification which service is related to the currently selected
channel. (“TWR”, “ATIS”, “APPROACH”, etc.)
o9 recently selected VHF channels are automatically stored.
GT6201 Certification: Bundesaufsichtsamt für Flugsicherung
Approval No.: D-0030/2014

Section 1 GENERAL DESCRIPTION
1.1 Introduction
This manual describes the operation and installation of the GT6201 VHF Transceiver Family. The
ID label on your device shows the part number for identification purposes.
Before starting to operate the unit(s), please read this manual carefully with particular attention to
the description referring to your device. This manual also contains several optional elements of the
system (second controller for example), that may not be contained in your delivery package and in
that case are not applicable.
The manuals DV 17001.03 I&O (“Installation and Operation”) and DV 17001.04 M&R
(“Maintenance and Repair”) contain the following sections:

1.2 Purpose of Equipment
The GT6201 enables voice communication between ground and airborne station, using the very
high frequency band between 118.000 and 136.9916 MHz respectively 136.9750 with a selectable
channel spacing of 8.33 kHz or 25 kHz. The GT6201 VHF Ground-Transceiver is ground-based
equipment.
The GT6201 Transceiver can operate using ground power when installed in desk-cabinets or
19 inch racks, but is also dedicated to applications where low power consumption is required.
GT6201 is capable to operate from standard 14V DC and 28V DC installations and from 12V DC or
24V DC batteries.
1.3 General Notes
On the following pages the GT6201 transceiver is named in two different senses. The common
model name GT6201 is used in such cases a description applies for all variants of the GT6201,
otherwise the applicable models are typed with its complete model name
In this document the word “frequency” is also used in the sense of “channel name”, as defined in
ICAO Annex 10, Volume II.

In this document the word “memory channel” or “channel” means a memory place identified by a
channel number, where a frequency may be stored for later use.
1.3.1 GT6201 Single Block Transceiver
Air traffic services require efficient, secure, modern and user friendly communication equipment.
Becker´s radio systems offer well-proportioned solutions for small to medium-sized airports,
airfields or airline operations stations.
Assembled with quality-proven components, engineered with state-of-the-art technology and
driven with a customer focused philosophy, our radio-communications solutions provide high
flexibility and scalability.
In continuation of the very successful portable/mobile VHF transceiver BECKER AR4201, the
new VHF Transceiver GT6201 for ground applications offers latest standards and is ideally suited
for vehicle installations and constitutes the basis element for a variety of other products like the
GK61X portable system or the TG660 (19 inch) series.
Designed for operations at airfields and airports in a very demanding environment, the GT6201
offers latest technology and comfortable operation on all frequency channels in the aeronautical
VHF frequency band, adjustable in 25 kHz steps as well as in 8.33 kHz steps. The user friendly
operator menu and the extensive setup possibilities allow a very personal setup for the user. The
large, clear and dazzle-free LC display shows the active frequency and either the standby
frequency or memory channel.
With an output power of 6W or 10W, the transmitter is strong enough for medium range
communications, ensuring a low cost of ownership for the customer.
Derived from its airborne counterpart AR6201, the GT6201 is the robust, reliable and flexible
solution for your ground operations.
