General description
The station is designed for mounting in 19-inch rack systems or in an ATC desk.
The station operates in a AC supply voltage range from 90 V ... 230 V ±10% / 50 . . 60 Hz. The nominal
supply voltage in DC operation is 24 V.
If the AC voltage supply fails, a control circuit switches over to external DC voltage.
The station is capable of delivering up to 20W power (RF-carrier) to an external antenna via 50-W coaxial RF-cable
The station has simple user-friendly HMI, the main components are the dot-matrix liquid-crystal display
(LCD) and controls (rotating knob and buttons). The information about current operating mode, active
selected operating frequency and operating status of the equipment are displayed on the LCD. Control
elements (knob, buttons) enable user to change operating modes, select operating frequency or channel and a stand by switch for switching on and off.

TG 560 - (X)-(XX)
1.3.1.1
Remote control VHF transceiver
The transceiver core module inside the TG 560 - (X)-(XX) is called RT 5202 - ( ).The RT 5202 -( ) is a
remote controlled VHF transceiver. The RT 5202 - ( ) is controlled from the microprocessor on the
front panel board of the station via a RS 232 interface.
The rear of the VHF transceiver contains the main connector “male” for connection to the analog board
and the antenna jack “female”.
The VHF transceiver is equipped with a 20 W output power transmitter.
During transmission, the transmitter provides a natural sidetone signal.
If a 4:1 mismatch is applied to the transmitter output terminal , then the output power is reduced automatically to 40 % of the manufacturers declared nominal output power.
The VHF transceiver is fitted with a protective circuit to protect against jamming of the transmit button
or a short circuit on the PTT line. The time limit setting for “stuck PTT” is 3 minutes.
The nominal RX audio output voltgate of the transceiver is 1 V rms.
The sidetone level is - 3 dB related to nominal RX audio output voltage.
1.3.1.2
Analog board
Primary functions of the analog board are :
r
Providing interface for input audio signals from microphones and two-wire line, amplification and filtering of those signals switching the inputs to the TX modulation input of
the transceiver RT5202.
r
Providing interface for output audio signals coming from RX-part of RT5202, amplification, filtering and switching of those signals. Internal and external speaker, headphones, voice recorder and two-wire line can be connected to the equipment.
r
Providing electrical interfaces for external discrete control lines (PTT’s,
RF-Switch-over and so on).
r
Power management and providing low-voltage power supply for the components of
the system.
r
Feed-through of the control signals from microcontroller on the front panel board to
the transceiver RT5202. RS-232, the PTT and some other signals are passed directly
to RT5202 from microcontroller via analog board. The analog board provides all analog and discrete-signal external interfaces of the equipment. It also contains
low-voltage power supplies for analog and digital processing.
DV 68410.03 Issue 1 07/04

TG 560 - (X)-(XX)
Microphone inputs
The microphone inputs are designed for standard microphones unbalanced, dc coupled, provide the
power supply for the mike. A dynamic mike input balanced and symmetrical line input . The inputs are
connected to a dynamic volume compressor inside of the remote controlled transceiver which keeps
the modulation voltage constant over a wide input voltage range.
The type of microphone – dynamic or standard can be selected by switches on the analog board. The
mike input on the front panel (mike) is dynamic mike only.
Audio outputs
The station has four different outputs:
r
Phone output
r
Speaker output (speaker is switched off in transmit mode)
r
Line out
r
Voice recorder
The phone output is greater than 100 mW @ 600W. The rated output power loudspeaker is 2W/4W.
The LINE_OUT – AF output nominal output level is 0 dBm 600 W. The output level phone output and
speaker output is adjustable with a potentiometer within the range –20...+10 dBm. The voice recorder
output is -12 dBm to 0 dBm 600 W balanced (adjustable with internal potentiometer).
Sidetone output
The sidetone signal is switched to the line output and phone output in transmit mode.
1.3.1.3
Front panel board
The front panel board is the human-machine interface and controls all other subsystems of the station.
The microcontroller placed on the front panel board exchanges control information with the remote
control transceiver via RS-232 interface, enabling change of operating frequency and other operating
parameters of the equipment. Another task of the microcontroller is the processing of all discrete control signals which come from outside (PTT etc.) and providing the corresponding control signals to the
subsystems and components inside the station. The microcontroller realises serial communication interfaces with remote control unit and Service PC which can be connected to the equipment. Service PC
is a computer with service software running on it, which enables setting of operating parameters of the
station, read out the list of failures etc.
The speaker is placed on the front panel.The speaker is switched off during TX transmitting. This
avoids acoustic coupling between speaker and the microphone, which can cause oscillation.
1.3.1.4
Optional coaxial relay
An auxiliary transmitter can be connected to the equipment. In this case optional coaxial relay and
coaxial jack must be installed. Auxiliary TX with higher power as provided by station is needed at
some ATC facilities. The station operates as receiver in this configuration. VHF antenna is switched to
the auxiliary TX if it is transmitting or it is connected to the remote control receiver operating as receiver.

1.3.1.5
Rear panel
The following are mounted on the rear panel:
The equipment connectors for connecting to the AC/DC power supply, voice recorder, remote control,
record/DF, external speaker/PTT and line aux.
The antenna socket for connecting the antenna.
A cooling fan is switched on if the heat-sink temperature at remote control transceiver exceeds
80°C. Cooling fan is switched off if the heat-sink temperature decreases to 75°C.
1.3.1.6
Filter board (A10)
The primary function of the filter board is suppression of electro-magnetic interference by filtering of all
signal lines coming from outside into the station. ESD protection elements are also placed on this
board as well.
1.3.1.7
In-band control board
The in-band control board is provided as option. It receives(sends) pilot-signals on the 600-Ohm line
from (to) remote communication equipment, realising control interface between the station and remote
control equipment. Control pilot-signals are transmitted within voice frequency band thus eliminating
the necessity of addition control lines (PTT and CALL) between the remote control transceiver and the
station. Remote control transceiver looks like a handset with a PTT-button and a call indication signal
lamp, lighting when RX signal is present on the 600- Ohm Line, as well as a control circuitry complementary to the one on the in-band control board.
1.3.2
Self test
The self test consists of three different test routines.
r
PBIT
is automatically initialized when the station is switched on.
r
CBIT
runs permanently in the background during the station is
switched on.
r
IBIT
The IBIT is started by pressing ”TEST” button.
The self test is described in detail in section 3 and 4.

Thermal considerations
Convection cooling is improved by following measures: vent openings in the cover of the station, thermal contact between side panel and transceiver unit , by switching on the fan, if convection cooling is
not sufficient to hold the temperature of transceiver heat-sink below 80°C.
Going out from the construction measures taken in order to improve thermal mode, following provisions should be made when installing the equipment:
l
Don’t close the openings on the cover of equipment.
l
Maintain minimum 5 mm clearance between side panel of equipment and the side panel of equipment rack.
l
Provide the free way for the fan air flow streaming out of equipment.

The required storage channel is selectable by pressing numeric keys 0-9.
Incorrect input is ignored (digits other than 0.1.2 in the first position and channel numbers greater than
20).
If selected channel is FREE, ”F” letter appears. If selected channel was used earlier, ”F” letter does not
appear and user can overwrite previous data.
If incorrect (channel) number is input, the bottom line CHxx must be inverted for 1 seconds and the indication goes back to the previous indication.
The storage is acknowledged by pressing the ”E” key. After acknowledgement the indication goes
back as described for standard mode.
If the ”E” button is not pressed within 10 seconds after pressing digital key, the station goes back to the

Transmit/Receive mode of the station
1. Switch on the station using the ON/OFF STANDBY switch on the front plate. The “Becker Logo” appears for 2 seconds in the LC display
Note
The equipment works with AC-power as standard. If the AC-power fails, an automatic switch over to
DC-power is performed. If AC-power becomes available again, automatic switch over back to
AC-power is performed.
Depending on which power the station is operated, the associated indication at the front panel (LED
green) is illuminated
If the station switches from AC to DC-power or vice-versa, the station is operable with the same
functions and settings as previonsly.
The settings selected before switch off is automatically restored when the station is switched
on.
2. Operate the transmit key and call the corresponding station. Hold the microphone close to your lips
for optimum speech transmission.
NOTE
The transmit mode appears in the upper right part of the display ”ON AIR”. During transmission a protective circuit prevents a frequency change or frequency channel change or
mode change.
3. Using the “VOL” volume control set the correct reception volume whilst the called station is answering. The external and internal speaker can switched on or off with the “LSP” key on the front panel.
4. Switch on the squelch (press SQL key). ”SQL ON” indication appears in the right middle part of the
display. Weak reception signals and reception noise are suppressed.
The squelch threshold setting function can be activated by long pressing the SQL key. The actual
digital threshold value is indicated in the top part od LCD betwwen “SQL level” and”dB” indications.
The squelch level display format is “XX dB, whereby “X” is a decimal digit. If the “E” key is pressed,
the squelch threshold is increased in step of 1dB. If the “S” key is pressed, the squelch threshold is
decreased in step of 1 dB. If the “SQL” key is short pressed or if no key is pressed within 5 seconds

Safety instructions
The following instructions must be followed for safe operation of the station:
l
A speech test is to be performed before startup and it should be noted that if the
speech test is carried out close to the station the results may be positive even if the
antenna cable is broken or short-circuited. At a distance of 5 to 10 km no connection
will be made.
l
Use a loud voice for speech communication and hold the microphone close to the
lips. Otherwise ambient noise can be intrusive and make understanding difficult.
l
Use only microphones or headsets which are suitable for use in aircraft. Incoming radiation on the equipment antenna can affect the integrated amplifier of the microphone (feedback). This is noticeable in the station by whistling and/or heavy distortion.
The described disturbances can occur in different ways on the different transmission
channels.
l
Transmit buttons can stick and cause continuous transmission. Therefore, when
transmitting ensure that the display (ON AIR) disappears when the transmission button is released.
WARNING
l
High voltages inside. Refer servicing to qualified personnel
l
Disconnect mains cable before opening the cover.
