Introduction
S. P. Radio A/S
For more than half a century S.P. Radio A/S has been the market
leader within maritime radio communication.
SAILOR
The communication products and systems of S. P. Radio are
recognized under the brand name SAILOR.The Sailor name has
become a guarantee of reliable and technologically superior radio
equipment, ranging from basic VHF units to satellite systems and
complete compact GMDSS solutions.
Products
The SAILOR COMPACT 2000 GMDSS is based on the well proven
range of Sailor products specifically developed to meet the GMDSS
requirements and supported by a world-wide Certified GMDSS
service concept, giving several hundred reasons for shipping
companies to choose equipment manufactured by S. P. Radio A/S.
Today S.P.Radio A/S is recognized as the world’s leading supplier
of GMDSS solutions.
The SAILOR COMPACT 2000 GMDSS has already been and still is
constantly supplied to a large number of the world’s leading shipping
companies and national naval fleets. It is a complete GMDSS
solution which matches communication and safety needs exactly -
regardless of whether you operate with A1, A2, A3 or A4.
The System 4000 GMDSS sets new standards. It is constructed on
the basis of our comprehensive experience developing GMDSS
equipment. It satisfies all the relevant requirements regarding safety
and efficiency.The System 4000 presents a large number of
attractive convenience and safety facilities, either as a complete
solution or as a series of stand-alone products.
Sailor has a long history as a satellite communications supplier
offering a full programme of satellite systems which includes Mini M,
SAT-C and a number of stationary satellite systems. Our SAT-B is a
breakthrough in maritime aerial technology and reliability.The SAT-B
is the best possible choice when high quality speech transmission,
top level security and the capacity to deal with large volumes of
telex, fax, data and high-speed data (HSD) transmissions are required.
Training certification
Training of deck officers to meet the requirements within the concept
of GMDSS, as to operation of equipment and basic understanding of
the systems, is an extremely important factor for the overall success-
ful implementation of GMDSS.As a unique initiative for GMDSS
solutions, we can supply a complete software training programme for
on-board training, to be used as preparation in order to fulfil the
GMDSS requirements for obtaining the
General Operation Certificate.
Service
A world-wide Sailor GMDSS certified service concept has been
established in order to provide the shipping industry with a highly
professional and uniform level of service.The Sailor GMDSS
Certified Servide Centre concept, which is constantly monitored,
ensures that replacement units and spare parts are available at all
the Sailor Certified Service Centres around the world. Service
centres which are in position along all the major shipping routes.
Furthermore the Certified Service Centres ensure that technicians
with an annually updated training are ready to provide service 24
hours a day, 365 days a year.
Maintenance
Because of the fact that GMDSS equipment has been installed on
board ships in order to meet the SOLAS (Safety of Life At Sea)
convention, manufacturers and suppliers of GMDSS equipment have
a certain responsibility to secure reliable supplies of equipment and
spares in the years to come.
Therefore shipowners operating ships both locally and internationally
should be fully aware of the importance of fitting GMDSS solutions
which will be fully supported by the manufacturer.
It is a firm policy of S. P. Radio A/S, as the world’s major manufac-
turer and supplier of GMDSS solutions, that for both the present
GMDSS solutions and for future, alternative product solutions, all
Sailor GMDSS systems will be entering the next century, in fully
parallel production.

2.2 Power Supply
The standard power supply for the VHF unit is 12V DC.
For 24V DC supply an external power supply with the type number N420 can be used. The N420 is in
principle a 24V DC to 13.2V DC serial regulator.
For 110V AC, 127V AC, 220V AC or 237V AC operation, an external power supply with the type number
N163S must be used together with N420.
Fuse
The fuse is a standard 10A mini car fuse. There is a spare fuse in the power cable connector.
2.3 Aerial
All common 50 ohm aerials which cover the used frequency range with a reasonable standing wave ratio, maximum
1.5, can be used.
The aerial is connected to the set by means of a 50 ohm coaxial cable with low loss, e.g. RG213U. At the cable end
a PL259 plug is mounted.

Installation RT4722
2.3.1 Placing the Aerials
In a GMDSS CLASS A installation, there are always two aerials. These should be mounted in a place that is as high
and clear as possible - as illustrated below. Note that the primary transceiver aerial must be placed at a higher level
than the channel 70 receiver aerial.
