General Description
Introduction
12 Transceiver Family 620X DV14307.03 Issue 04 March 2016
1.1. Introduction
AR-, RT-, RCU620X VHF Transceivers are a modern family of communication equipment that have
comprehensive capabilities and significantly extend the typical aeronautical transceivers.
Despite its small size and weight the devices include inter alia:
• Sensitive receiver which meets the most recent requirements of ED-23C, including the
ability to work in the offset-carrier (climax) operation in 25 kHz and 8.33 kHz channel
spacing (class H2).
• Receiver includes SCAN (dual watch) mode. This allows simultaneous monitoring of two
different VHF frequency channels without interrupting communication on the active
frequency.
• High efficiency transmitter, which delivers more than 10 W modulated, or un-modulated,
output power at 28 V supply voltage, or 6 W at 12 V.
Lower power consumption allows longer operation from battery.
• Extended built-in intercom which can work as:
o 4-way intercom with isolation mode – passengers could continue conversation or
listening to music from MP3 player at the same time as pilots talk via intercom or
communicate with the tower.
o 2-way intercom for tandem operation – pilot and co-pilot work with separate
controllers and can control their individual audio parameters, like volume or VOX.
This mode is preferred especially for training due to full synchronization of LCD
contents.
• Non-volatile memory for storing:
o 99 channels can be labelled manually for storage of VHF frequencies.
o 9 recently selected VHF frequencies are automatically stored.
For further descriptions we are using following terms for VHF transceivers, VHF remote transceiver
and remote control unit, instead writing their complete model number.
620X in general for the device family.
AR620X for: AR6201, AR6203 (Single Block Transceiver).
RT for: RT6201 (Remote Transceiver).
RCU for: RCU6201 (Remote Control Unit).

1.2. Purpose of Equipment
The 620X transceiver family enable voice communication between aircraft or between aircraft and
ground using the very high frequency band between 118.000...136.9916 MHz respectively
136.9750 MHz with a selectable channel spacing of 25 kHz respectively 8.33 kHz. The wide scope of
accessories also allows usage of the 620X VHF transceivers in ground-based applications.
The 620X Family is dedicated to applications where low power consumption is required. They are
capable to operate from standard 14 VDC and 28 VDC installations and from 12 VDC or 24 VDC
batteries.
Ultra low power consumption with extremely wide DC supply voltage range as well as compact and
lightweight design allows application for gliders and leisure aircraft up to 2000 kg and balloons.
Built-in 4-seat configurable intercom, transmitter output power up to 10 W and option for connection of
two controllers in tandem configurations extends the flexibility of the 620X Family.
The 620X transceivers also provide additional options such as:
• Intercom functionality for voice communication between aircraft crew and passengers
• Squelch functionality that automatically mutes receiver audio signal until clear signal is
received to avoid unwanted audio noise
• Scan functionality for simultaneous monitoring of two VHF channels (receive mode)
• AUX audio input for connection of additional audio devices like navigation receiver,
warning-tone generator, or MP3 music player.
• VHF channel database for easy access to predefined frequency channels
• Tandem functionality for synchronized operation of two controllers
1.3. General Notes
The word "frequency" also used in the sense of "channel name", as defined in EUROCAE,
document ED-23B chapter 1.3.2.
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.

General Description
Features Overview
DV14307.03 Issue 04 March 2016 Transceiver Family 620X 19
Audio Outputs
The 620X transceiver includes four fully configurable outputs:
• Headphone 1 output, rated output power is 300 mW into 75 Ω.
• Headphone 2 output, rated output power is 200 mW into 75 Ω.
• Speaker output, rated output power is 4 W into 4 Ω.
• LINE-OUT output intended for ground station use only
Note: Headphone 2 and speaker output cannot be active at the same time
Mike Inputs
The VHF transceiver has an input for dynamic microphone (DYN_MIKE) and an input for standard
microphone (STD_MIKE).
The 620X transceiver provides four microphone inputs:
• Standard microphone input 1 (STD_MIKE1)
• Standard microphone input 2 (STD_MIKE2)
• Standard microphone input 3 (STD_MIKE3)
• Dynamic microphone input (DYN_MIKE)
Each input is able to operate with one single microphone or with two microphones of the same type
connected in parallel.
AF Auxiliary Input
The AF auxiliary provides the interface to connect an external audio source (e.g. NAV, music-player)
to the transceiver. Interconnection of multiple external audio sources on this particular port requires
additional external decupling/isolation resistors. The external audio is audible only when the
transceiver is in receiving mode.
The individual audio volume is set directly at the particular external equipment.
Side Tone
The side tone is available on the headphone output during transmission. The side tone volume
automatically adapts to the intercom volume setting.
Squelch Operation
When enabled the squelch (muting) circuit suppresses weak signals. There are two kinds of squelch
methods implemented, carrier- and noise-squelch. Carrier-squelch depends on the received signal
strength and is adjustable in configuration setup; the noise-squelch depends on the detected noise
level and is adjustable in the user menu.
Memory Channels
The memory function allows storage of up to 99+9 frequencies. A user defined text label is assignable
for each stored frequency. Additionally the last recently used 9 (active) frequencies are stored
automatically as "LAST" channels.
Intercom Operation
The built-in intercom circuit provides internal communication via between pilots and passengers via
connected headsets. The 620X system has two intercom circuits, "Front row" and "Back row". You can
connect a maximum of four headsets, e.g. pilot & co-pilot to first circuit and two passengers to second
circuit).
Scan Mode
Scan mode provides a dual watch function. The device is capable of monitoring frequencies on two
different channels, active & preset simultaneously. The signal of the active frequency will always be
audible, since it will have priority at all times.
General Description
Features Overview
20 Transceiver Family 620X DV14307.03 Issue 04 March 2016
Tandem Operation
Tandem mode enables operation of two controllers simultaneously. The controllers synchronizing
each other in such a way, that both display the same information.
Illumination
The illumination of LCD and push buttons can be controlled either directly from the front panel via the
user menu or externally via the dimming input lines. If external dimming selected, the illumination
curve (brightness to voltage relation) is adjustable in configuration setup.
LOW BATT Indication
The transceiver monitors power supply voltage. If the supply voltage drops below the adjustable
threshold, the display indicates the message "LOW BATT". If the power supply voltage drops further,
emergency operation mode activates.
Emergency Operation
If the power supply voltage drops below 10.25 V, the transceiver continues operation with degraded
performance. If power supply further drops below 9.0 Volt, the unit automatically switches off.
Built-in Tests PBIT and CBIT
After power-up, the unit performs a self-test (power-up built-in test / PBIT). During PBIT, the
transceiver displays "WAIT" and additionally the corresponding software versions of both, the control
head (CH) and core module (CM) become visible.
If faults are detected during PBIT, the error message "FAILURE, press any key" is displayed. If no
faults are detected the transceiver automatically activates the last active mode set at last power-off.
During normal operation, a continuous built-in test (CBIT) permanently verifies the correct operation of
the unit. If detecting a problem during CBIT an error message become displayed.
Configuration Setup
Configuration of parameters such as mike sensitivity, mike type selection, speaker enable/disable and
several other parameters, via the configuration setup provided.
Service Mode
The service mode is a special configuration mode accessible via RS422 interface with a proprietary
serial data communication protocol. This mode is for use by authorized maintenance organizations
during aircraft service on ground only.

1.7.4. Emergency Operation
For power-supply voltages below 10.25 V, the speaker output of the
transceiver will automatically switch "OFF" without further indication.
If the device enters emergency operation, the speaker is switched "OFF" due to degraded
performance. Depending on settings in configuration setup "LOW BATT" may be indicated if supply
voltage drops below a predefined threshold to indicate to the user, that he should connect his headset
as the speaker may be switched "OFF" soon). In this case, a headset is required to continue operation
of the transceiver. This data is applicable for AR620X and RCU6201.

2.6. Installation and Configuration
Connection to the following equipment is required as minimum for 620X transceivers:
• Power supply
• Antenna
• Microphone (direct or via external audio panel)
• Headphone or speaker (direct or via external audio panel)
• Push-To-Talk (PTT) switch
Use only cables which are qualified for aircraft use (self-extinguishing).
Use AWG 20 for power supply and AWG 22/24 for other cables.
Fit sleeves over the solder joints on the equipment connector. Crimp
connectors are also available from Becker.
Protect the power supply with a 7.5 A fuse.
The VHF transceiver is protected internally by a 5 A fuse.
• Type-specific cable harnesses are also available for the aircraft wiring (contact Becker
Avionics for detailed information).
• No RF antenna cables or HF cables should be included in the cable harnesses of the
system. Avoid routing of the cable loom along with other wiring, which carry audio power
or pulses.
• Check the wiring carefully before powering up the unit and check particularly that power
supply lines are not interchanging.

2.7. Antenna Installation
The transceiver requires a standard 50 Ω vertically polarized VHF antenna. Follow manufacturer's
instructions for antenna installation. In addition, consider the following recommendations:
• The COM antenna shall be on an electrical conductive surface or, on a ground plane with
sufficient area of approximately 60 x 60 cm installed. (VSWR ≤ 3:1)
• Separate the COM antenna from any installed GPS antennas by at least 50 cm and as far
away from any ELT antenna.
Note: Some ELTs have exhibited re-radiation problems generating harmonics that may cause
interference with other receivers like GPS. This can happen when the transceiver or other COMM
devices are transmitting on certain frequencies such as 121.5 MHz or 121.175 MHz, which may
cause the ELT output circuit to auto-oscillate.
2.8. Configuration Setup
The configuration setup enables the avionics technician to set up the equipment configuration on
ground.
We do not recommend performing changes on the configuration setup in-flight.
In most cases, entering configuration setup will be from the primary controller to access controller and
transceiver parameters. If installed, the second controller (RCU6201) should be switched off.
Configuration setup on RCU6201 gives access to parameters of second controller. RCU6201
configuration setup shall be used only if different settings for "BRIGHTENSS" or "ILLUMINATION
CURVE" are required.
Note:
• For single block AR620X, primary controller is this one directly connected to transceiver,
for remote RT6201 transceiver primary controller is this one connected to primary control
interface.
• After power on the second controller (RCU6201) parameters are synchronized with those
stored in primary controller. Any stored parameters in second controller (RCU6201) will be
overwritten!

The factory setting is 110 mV.
The VU meter displays the current signal level on the audio input and
also displays the highest signal value for the last 3 seconds.
When speaking normally into the microphone the bar graph should
remain within the recommended predefined range
Note: Adjust the microphone sensitivity by keeping the cockpit
noise suppression as high as possible, this will ensure correct
modulation.
If the sensitivity is adjusted to a smaller value (e.g. 10 mV) the cockpit
noises may become louder than for a higher adjustment (e.g. 100 mV).
Otherwise, adjusting the sensitivity to a very high value (e.g. 1000 mV),
the cockpit noise is very much reduced, but the modulation of the
transmitter might be not sufficient.
The installer shall perform a communication check after modification of
this parameter. Recommended is to perform this check with and without
a running engine.
Note: Menu available on primary controller.
For installations with high interferences it is recommended to use

SQUELCH THR
Minimum Adjustment of 6 means:
Weak RF signals can trigger the Squelch threshold and the voice signal
might be low combined with a noisy background.
Maximum adjustment of 26 means:
Only strong RF signals will trigger the Squelch threshold. The voice
signal will be audible very clear with very low background noise.
Weak RF signals may not trigger the Squelch threshold and therefore
the audio may not be heard by the pilots.
Note: Adjustment of the "SQUELCH THR" is available via the

Connect the cable shielding to pin P1-6, which is the low side input for dynamic microphone. Because
in AR6201 this input is balanced, the cable shield is no longer connected to ground (unlike it was with
the AR4201). In most cases, it is not a problem.
If interference with the microphone signal does occur, it is recommended to carry out the following
modification:
Connect Pin P1-6 with Pin P1-8 (the cable shield is grounded). See Figure.

The AR6201 provides on pin P1-24 a low signal when the unit is switched on and a high impedance
signal, when switched off.
Note: This is not compatible to the AR4201, which provided a positive power supply
when switched on and high impedance when switched off.
In cases where slave equipment needs to be switched ON/OFF in sync with the AR6201 connect a
relay to pin P1-24.
2.13. Post Installation Tests
Note: It is assumed that the "Configuration Setup" (see "Configuration Setup", page 53) has
been done before the Post Installation Tests will be carried out.
Once the 620X is installed, complete a test procedure to verify system functionality. Ensure
compliance with authority required procedures. Refer to the installation order of the minor change
document or use an own approved test protocol for VHF units. The following chapter provides
guidance for such tests.
2.13.1. Mechanical Installation and Wiring Check
• Verify all cables are fixed securely and shields connected properly to signal ground.
• Check the movement of aircraft controls to verify there is no interference.
• Verify all screws are tight and the connectors on the rear side of the unit are secured.
2.13.2. Power Supply
• Check the power supply lines and confirm correct polarity.
• Confirm that the aircraft power supply is within the specified limits, with and without a
running engine.
2.13.3. Receiver / Transmitter Operation
• Power up the 620X and tune it to a local station for a communication test.
• Verify that the receiver output produces a clear and readable audio and ask the local
station for proper readability for the transmit signal of the 620X.
• Repeat this communication test with an airborne station within ≈ 20-40 NM (Nautical
Miles).
2.13.4. Antenna Check
• Check the VSWR (voltage standing wave ratio) over the complete frequency band (e.g. by
using a VHF Reflection-Coefficient Meter).
The VSWR ratio should be less than 2:1 and is not acceptable when exceeding 3:1.
2.13.5. Interference Check
• Check the 620X while engine is running and all other avionics/ electrical systems on the
aircraft are powered, to verify that no significant interference exists.
• Check also that the 620X does not cause significant interference with other systems.
The installer´s standard test procedure may be used for the interference check and the table can be
taken as a reference. Depending on the individual avionic systems installed in the aircraft, it might be
necessary to extend the following checklist accordingly.

For the remaining avionic equipment repeat all interference checks during a flight and include all
equipment not previously checked out on ground. A communication performance check in the low, mid
and high frequency band of the 620X should be included.
• Verify the receiver output produces a clear and understandable audio output.
• Verify the transmitter by contacting another station and getting a report of reliable
communications.
• Perform the range check with a station at least 100 m from your own position.
• Check the intercom function by talking into the microphone, while the engine is running at
cruising rpm. You should hear yourself and/or your co-pilot loud and clear.
• Switch "ON" the squelch and check that the normal radio noise, without a present carrier
signal, it will be constantly suppressed. The threshold of the squelch can be set in the
user menu.
2.13.6. Flight Test Check
It is highly recommended to perform flight test as final installation verification. The performance of the
620x may be verified by contacting a ground station at a range of at least 50 NM while maintaining an
appropriate altitude and over all normal flight attitudes.
• Check the performance in the low, mid and high band frequencies.

2.14. Trouble Shooting
Problem
Possible Reason
Proposed Solution
No Intercom function.
(You can’t hear yourself when
talking into the microphone).
VOX is switched "OFF", or
adjusted to a too high value.
Adjust the VOX to a lower value. A
value of
"-15" is suitable in most
cases.
Refer to "Configuration
Setup
", page 53).
The intercom volume adjusted to
a too low value.
Adjust the intercom volume to a
higher value. A value of
"37"
produces already a quite loud
intercom signal.
Refer to
" Configuration Setup",
page
53).
The sensitivity of the microphone
input is not sufficient. The level is
adjusted to a too high
value.
Adjust the sensitivity of the
microphone input to a lower value.
For most common avionic headsets
a setting of 50…120 mV is
sufficient.
Refer to
"Configuration Setup",
page
53).
VOX threshold is not adjustable.
VOX is always off.
VOX is inoperative, because
speaker is on.
Switch speaker to "OFF".
Refer to
"Configuration Setup",
page
53).
Too high cabin noise during
intercom / transmit operation.
The sensitivity of the microphone
input is too sensitive.
Adjust the microphone sensitivity to
a higher value to ensure the cabin
noise relatively reduces.
Recheck transmit
operation and/or
Intercom function.
Refer to
"Configuration Setup",

The noise suppression function
of the squelch is not working.
(Receiver noise is always
present).
Some avionic (especially non
ETSO/TSO approved avionic)
can produce quite high
electromagnetic interference,
which is receiving by the
AR6201
-().
Reduce the interference emitted by
the avionic around by improving
shielding, distance or grounding.
The interference may also been
suppressed by adjusting the
squelch to a higher value.

Continued Airworthiness
96 Transceiver Family 620X DV14307.03 Issue 04 March 2016
Problem
Possible Reason
Proposed Solution
Antenna VSWR exceeds 3:1.
Possibly caused by a defective,
or insufficient counterpoise for
the antenna.
Check for sufficient size of the
counterpoise and make sure there
is no mechanical defect on the
antenna.
The impedance of the antenna
cable deviates significantly from
50
Ω.
Make sure the used antenna cable
has 50 Ω impedance and the cable
is not bend or kinked on its way
from the radio to the antenna
Defective BNC connectors on the
antenna cable.
Check for proper crimp/solder work
on the BNC connectors and rectify
as far as necessary.
2.15. Continued Airworthiness
The 620X family maintenance is defined as "on condition" only. No scheduled or regular maintenance
of this product is required.
It is recommended to check the frequency accuracy of the airborne transceiver after 7 years.

ensure safe operation of the VHF transceivers.
3.1. Device Description
In this section the figures for illustrating display content mainly show
transceivers working in 8.33/25 kHz mixed mode. Dedicated pictures for
25 kHz mode are not explicitly shown (they differ only in number of digits
for frequency).
The HMI actions described in this section can be performed on primary
controller or on optional secondary controller RCU6201.
The following graphics of the display content show the 8.33 kHz channel
spacing for all possible operation modes.

Operating Instructions
Device Description
98 Transceiver Family 620X DV14307.03 Issue 04 March 2016
A voice communication test shall be performed before starting
the engine.
It should be noted that, if the communication test is carried out
close to a ground station, the results may be positive even if the
antenna cable is broken or short-circuited. In such a case, at a
distance of 5 to 10 km and above, communication might not be
possible.
• Speak always loud, clear and not too fast for optimal voice communication.
• Keep the microphone always close to the lips otherwise a special suppressing circuit in
the VHF COM will not be capable to suppress normal cabin noise.
• Use only microphones or headsets which are suitable for use in an aircraft.
o In aircraft made of wood, synthetic materials or in gliders or helicopters, incoming
radiation can affect the integrated amplifier of the microphone (feedback), noticeable in
the ground station by whistling and/or heavy distortion.
If the power supply voltage drops below the "Low Battery Threshold" (default value is 10.5 V), the
"LOW BATTERY" message will appear each 3 seconds in the lower part of the display.
If the power supply voltage drops below 10 V the system enters
power saving mode:
• Speaker output of the transceiver is automatically
switched "OFF"
• Speaker sign will no longer be presented on LCD
display
• The pilot must use headphones to continue listening.

In transmit mode several user actions such as changing frequency selection mode or channel spacing
mode, which are normally allowed in receive mode, are blocked. (As an exception in standard mode
the "Preset" frequency may still be changeable, even during transmission).
No intercom operation is possible in transmit mode.
The sidetone (demodulated audio of the emitted signal) is available on the headphone output. The
transmit mode automatically deactivates the speaker.
Note: Transmit mode is automatically terminated (return to receive mode) after
120 seconds of continuous transmitting even if PTT is still pressed. In this case
"STUCK PTT" is indicated (refer to page 113). For initiation of a new
transmission, /PTT line needs first to become inactive.
3.5. Frequency Selection Modes
Following frequency selection modes are available on AR620X and RCU6201:
• Standard mode

During this procedure, the display looks similar to the channel mode with one difference
that "STO" appears on the left side of the display.
3.5.4.1. Store
The transceiver provides two databases:
• User channels database - provides 99 channels CH01 to CH99 to store frequencies with
the possibility to apply a customized label (identifier) with max. 10 alphanumeric
characters.
• Last channels database - automatically stores 9 last used frequencies with customized
identifier if applied, easy to recall as LAST 1 to LAST 9.
Any frequency can be assigned to any channel within the range from 118.000...136.9916 MHz by
simply pressing the "STO" button. All 99 channels are editable. By entering the storage procedure, the
device will first propose the next free channel for storing the active frequency. The label "FREE"
appears together with the channel number, if the selected channel is vacant. A selected channel with
an already stored frequency, has the label "USED".
If the same frequency is stored a second time, then the existing data (frequency, label/identifier data)
is offered to store. If the frequency has no label attached, ten underscore digits allows to insert a label.
The cursor automatically appears on the first position.
The data can be stored to:
• Next free channel (offered from system).
• A selected free channel.
• A selected used channel (the existing data will be replaced).

Operating Instructions
Auxiliary Audio Input
DV14307.03 Issue 04 March 2016 Transceiver Family 620X 109
3.9. Auxiliary Audio Input
The transceiver has a dedicated auxiliary audio input e.g. for MP3 player connection.
With auxiliary input enabled in configuration setup, the auxiliary audio input signal mixing with the
received signal from antenna (passing squelch) and the intercom signal (when activated).
When intercom operates in ISOLATION mode, auxiliary audio input signal is audible on headphone
2 output, even if radio communication (transmission/receiving) is active.
AUX AUTO MUTE function depends on the AUX INPUT, selectable via the CONFIGURATION page in
the configuration setup. This function automatically mutes the audio signal from the auxiliary audio
input as long as the AR620X detects (based on squelch evaluation) a RX signal or the user
deactivates the squelch manually. If this function is disabled the signal from the auxiliary audio input is
permanently audible on the audio output, independently of the received signal or the squelch status.
Automatic aux attenuation functionality controls the auxiliary audio input. The level of the auxiliary
input signal attenuates if intercom is activated by VOX or by /IC discrete input. The auxiliary input
signal reverts to its previous value after intercom deactivation. The attenuation value can be adjusted
within the range from 0...40 dB.
3.10. Intercom Operation
Intercom operation may be triggered automatically via VOX (with adjustable threshold) or externally
via intercom switch.
The setting of VOX-threshold and intercom volume is accessible in the intercom menu, in tandem
configuration on primary controller only.
For a single block, the primary controller is the one directly connected to VHF transmitter. For a
remote VHF transmitter the primary controller is the one connected to primary control interface.
VOX-threshold and intercom volume for the second intercom circuit are controllable from secondary
controller RCU6201 (secondary controller is the one connected to secondary control interface).
The transceiver has two internal built in intercom circuits. Therefore, up to four headsets are
connectable. Pilot and co-pilot connect to the first intercom circuit. When intercom is active, both
microphone signals are mixed and amplified with each other and will be audible on both headphone
outputs. This enables internal communication via headsets between both pilots. Passenger headsets
are connecting to the second intercom circuit.
ALL mode - Everyone connected to the intercom will hear all communications (pilots hear passengers
and passengers hear pilots).
ISOL mode - Provides separate intercoms for the pilots (intercom circuit one) and the passengers
(intercom circuit two). This allows pilots to communicate with each other, and air traffic, while the
passengers are isolated. The passengers on the intercom circuit two can hear auxiliary audio (for
example from mp3 player) and can communicate with each other.
External "ISOL" input provides possibility to switch between ALL mode and ISOL mode. If the /PTT1
input is active and ISOL is active the passenger intercom operation on second intercom circuit is still
possible.
While transmit mode intercom operation is degraded. During receive mode the intercom operation
activates automatically via VOX (with adjustable threshold), or using the external intercom switch.
If intercom operation is active, the "IC" sign appears in the display.

operation) to +10 (VOX is less sensitive and only high microphone signals trigger the VOX threshold
for intercom operation).
Note: At a setting for VOX threshold of -15 a convenient behaviour of the VOX should
be achieved in most aircraft. This requires that mike sensitivity had been correct
adjusted (configuration setup). If the mike sensitivity is incorrect adjusted, VOX
may not work satisfying.
By changing VOX threshold level to above +10, VOX switches "OFF". In this case, "OFF" replaces the
