Ground to Air Communication
JOTRON supplies ground to air communication solutions for all ground to air communication – VHF
and UHF / AM (oilrigs - helicopters, ship – helicopter, airports – airplanes). For use onboard ships or
oilrigs without need of remote control of the radio, the following TR-710 would be recommended.
For configurations were the radio needs to be controlled from another room/location, we
recommend the TR-7510 VHF/AM base-station with all remote control facilities.

software. One rack controller can control many radios.
Remote Control Unit for VHF/AM 7000 and UHF/AM 3000 series
1) When operator is to control the audio of the radio from another room/location than
where the radio is physically placed we recommend the use of the below ARC.
ARC – MK II Audio Remote Control (for 7000 and 3000 series)
The ARC is an audio remote control that uses 4wire E&M format to transfer RX audio,
TX audio, PTT and Squelch. The ARC has intercom-possibility: Several operators of
the same radio can connect their ARC units in cascade as one master and several
slave units. Internal loudspeaker with volume control and connections for headphone
and microphone. It operates from 220V AC with auto fail to 24V DC.
2) When the operator also needs to control the frequency from the same remote
position, we recommend to use the below ORC.
ORC – Operators Remote Control (for 7000 series only)
The unit has a 19” sub rack format and is 3U high. The ORC has RS-232/RS-485
interface. The operator can select operating frequency directly from radio’s channel
store, and there is a read-out of frequency information. The power is supplied from
ARC or Radio modules.
3) When the distance from the radio to the ARC and ORC is more
than 500 meters, we recommend the use of the below Audio and
PTT Modem.
Audio and PTT Long Distance Modem
For long distance remote control of audio, PTT and control signals
through a two/four wire leased telephone line.
Audio PTT and DATA L
ong Distance Modem
For data and audio transmission
Desktop box for ARC + ORC or separate ARC
Desktop Cabinet for 19’’ 3U installation
Jotron supply different types of cabinets, antennas, antenna-filters, multi
couplers, combiners, splitters and power amplifiers for both the VHF and
the UHF equipment. We tailor a system to your needs which will fully
comply to your critical co-location and frequency allocations.
Eex Communication Combined with Ground to Air Communication
Jotron can deliver a UHF/FM to VHF/AM repeater to solve the communication between aircrafts
and Eex platform.
The repeater is mounted into an Eex safe shelter or outside the Eex area.
The VHF/AM transceiver and the UHF/FM transceiver can be separately remote controlled using
Jotron remote control units.
BS 2000 Base Station and Repeater
The BS2000 series of base stations and repeaters are designed for continuous operation under
harsh climatic conditions and are available for all PMR frequency bands. The BS2000 is available for
remote control via an AC telephone line.

Examples of Configurations 7000 series:
The 7000 series VHF/AM radio system includes separate Receiver (RX) and Transmitter (TX) modules
(Fig. 1). Each module has facilities for being connected to other modules as a part of a main/standby
chain, and as a transceiver configuration.
TR-7550 / TR-7525 / TR-7510
Fig. 1
The radio units have a built-in coaxial relay for antenna switching, an Alarm output and a Select input
for automatic and/or manual main/standby selection.
In addition the transmitters have a Key/Mute output used to mute associated receivers during
transmitting periods.
The antenna is connected to the transmitters antenna output and routed via a built-in coaxial relay to
the transmitters antenna output.
From there a coaxial cable connect the antenna to the receivers antenna input.
When the transmitter is not keyed the coaxial relay will switch the antenna to the TX antenna output
and from there to the connected receiver.
When a key signal is applied to the transmitter the coaxial relay will switch the antenna to the
transmitter output. The same key signal is used to mute the receiver during transmission.
The audio line is connected in parallel to the transmitter and receiver.
Single Radio Setup,
Setup, general:
The radio modules can be controlled directly from the front panel and via
a range of remote equipment and accessories.
Remote Audio and PTT only:
The Operator at the remote site(s) is able to monitor traffic, and to
communicate on the current frequency of the local transceiver, through
the Audio Remote Control unit (ARC). A red LED indicator on the ARC will
alert the operator if there is an alarm on the local radio unit. (Fig. 2).
It is possible to connect more than one ARC to the same radio. The
number of wires can be reduced to two wires, but in this case the ARC will
loose functionality (the sq, alarm indicator will not be available).

Audio + DC line
Fig. 2
The maximum distance between ARC and radio unit is approximately 2 km, provided a high quality
screened cable is used.
To connect a pair of radio units as main/standby, the alarm output from main unit is connected to the
select input of the standby unit. Also, the initial main unit must be told that it is the main unit by
accessing its configuration programme and set its operation to Main. The standby radio unit is
automatically selected if there is an alarm on the main unit. The switch is a built-in coaxial relay.
Selection can also be done manually from the ARC (Fig. 3).

Long Range Audio and PTT
Communication via leased lines is made possible by use of the Audio/PTT modem, APM (Fig. 4). One
APM unit is able to access two transceivers (i.e. Main + Standby unit). In the below example with the
APM modem, the APM uses inband and FSK signalling and demands uncom-pressed audio line.

The Audio/PTT modem uses in-band tones for transfer of Squelch and PTT. Alarm (Main and Standby
unit) and Main/Standby selection uses FSK data. The 2 or 4 wires must be ordered specific as this is not
Limited Remote Access to Radio Control:
Adding an Operators Remote Control unit (ORC) to the set-up shown in Fig. 3, enables the operator to
toggle between the frequencies, which have been programmed into the radios. (Fig. 5) With the use of
this configuration it is recommended to use an ADAM-4510/4510S repeater. This unit simply amplifies,
or boosts, existing RS-422/485 signals to enable them to covers longer distances. It extends the
communication distance by 4000 ft (1200 m) or increases the maximum number of connected nodes by
32. In addition the 4510S version provides galvanic isolation between input and output so that any
difference in GND potential between each end of the RS485 line will be compensated for.
By the below example you may choose if you would like common audio – or separate RX/TX audio.
