Introduction

1.1 Introduction

The technical information in this document applies to the product and variants of GT6201.

• We use also the term GT6201 for descriptions instead writing the complete model
number.

• If a description refers to only one of the product variants its full name is used.

The manuals "Maintenance and Repair" (M&R) and "Installation and Operation" (I&O) contain the

General Description

General Notes

1.2 Purpose of Equipment

The VHF-Ground-Transceivers GT6201 are specified for operations on airports, airfields or airline
operation stations.

• The GT6201 is a ground-based equipment made for installation in desk-cabinets,
19-inch racks or cars.

o The GT6201-XX-R variant is a remote-controlled device, which does not include a

control panel. It can receive commands and supplies data through the control unit
RCU62X1 or a third-party controller.

• The GT6201 transceiver can operate with ground power but it is also made for
applications where low power consumption is required.

o GT6201 can operate from standard 14 and 28 VDC installations and from 12 or

24 VDC batteries.

• The GT6201 is for voice communication between ground and airborne stations.

o It uses the band between 118.000...136.9916 MHz respectively 136.9750 MHz

with a selectable channel spacing of 8.33 or 25 kHz.

• The sensitive receiver meets the most recent requirements of ETSI EN 300 676.

• 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 is on.

• The GT6201 has a non-volatile memory for the storage of:

o 99 channels with customized labels for storage of VHF frequencies.
o 9 recently selected VHF frequencies are automatically stored.

• The GT6201 is easy to install.

o Installation with four screws (rear panel installation).
o The dimensions correspond to the standard instrument diameter of 58 mm

(2¼ inch).

1.3 General Notes

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" is also used in the sense of a memory
position identified by a channel number, where a frequency may be stored for later use.

1.5.2 Audio Outputs

The GT6201 has four configurable outputs:

• Headphone 1 output:
o Rated output power is 300 mW into 75 Ω.

• Headphone 2 output:
o Rated output power is 200 mW into 75 Ω.

• Speaker output:
o Rated output power is 4 W into 4 Ω.

• LINE-OUT output:
o For ground station use only.

Note: Headphone 2 and the speaker output cannot be active at the same time.

1.5.3 Mike Inputs

• The GT6201 has four microphone inputs:

o Standard microphone input 1 (STD_MIKE1)
o Standard microphone input 2 (STD_MIKE2)
o Standard microphone input 3 (STD_MIKE3)
o Dynamic microphone input (DYN_MIKE)

• Each input can operate with one single microphone or with two microphones of the same

type connected in parallel.

Becker Avionics

General Description

1.5.4 AF Auxiliary Input

• The AF auxiliary input is the interface to connect an external audio source (e.g. other radio
services, music-player) .

o The interconnection of multiple external audio sources on this port make an

additional external decupling/isolation resistor necessary.

o The external audio is audible only when the transceiver is in receiving mode.
o The individual audio volume is set directly at the external equipment.

1.5.5 Sidetone

• The sidetone is available on the headphone output during transmission.

• The sidetone volume depends on to the intercom volume setting.

1.5.6 Squelch Operation

• The squelch (muting) circuit suppresses signals with strong signal noise (when enabled).

• There are two kinds of squelch methods implemented, carrier- and noise-squelch.

o The carrier-squelch depends on the signal strength and is adjustable in

configuration setup.

o The noise-squelch depends on the noise level and is adjustable in the user menu.

1.5.7 Memory Channels

• You can can store 99+9 frequencies.

o The user can give a defined text label to each stored frequency.
o The last recently used 9 (active) frequencies are stored automatically as "LAST"

channels.

1.5.8 Scan Mode

• The scan mode is a dual watch function.

o The device monitors frequencies on two different channels, active & preset

frequency at the same time.

o The signal of the active frequency is always audible it has priority at all times.

1.5.9 Illumination

• The illumination of LCD and keys is controlled from the front panel with the user menu or
externally with the dimming input lines.

• If external dimming is selected, the illumination curve (brightness to voltage relation) is
adjustable in configuration setup.

1.5.10 LOW BATT Indication

• The transceiver monitors the power supply voltage.

o If the power supply voltage is less than the adjusted threshold, the display shows

the message "LOW BATT".

o If the power supply voltage decreases further, an emergency operation mode

starts.

1.5.11 Emergency Operation

• If the power supply voltage is < 10.25 V, the device continues operation with decreased
performance.

• If power supply voltage is < 9.0 V, the device switches off automatically.

General Description

Becker Avionics

Scope of Functionality

1.5.12 Built-In Tests

Power-On Built-In Test

• After power-on, the device starts a self-test (PBIT).
o The display shows the message "WAIT" and the software versions of the control

head and the chassis module.

o If there is an error the display shows the message "FAILURE, push any key".
o If there is no error the transceiver changes to the last active mode before power

off.

Continuous Built-In Test

• During normal operation, a self-test (CBIT) permanently examine the correct operation of

the device.

o The display shows an error message, if there is an error during CBIT.

1.5.13 Configuration Setup

The configuration setup is for the configuration of installation and device parameters such as mike
sensitivity, mike type selection, speaker enable/disable and other parameters.

1.5.14 Service Mode

• The service mode is a special configuration mode.

• You can get access to the service mode through the RS422 interface with a proprietary

serial data communication protocol.

• This mode is for use by authorized maintenance organizations only.

when placing the device.

First Device Checkup

• Check the device for signs of transport damages.

• Please make sure that the indications on the type plate agree with your purchase order.

• Make sure that the equipment is complete ("Scope of Delivery", page 29).

Storage

If you do not wish to mount and install the device immediately, make sure to store it in a dry and clean
environment. Make sure that the device is not stored near strong heat sources and that no metal
chippings can get into the device.
