					All established mobile stations must have a
radio license, normally issued by the national
administration or another office/institute on
behalf of the national administration. The
conditions are laid down in the license
document. The license, or a copy of it, must
always be found on board the ship so that it can
be inspected by any authorities that are entitled
to do so.
   All cargo and passenger ships obliged to be
    fitted with radio stations in accordance with
    the SOLAS convention must have a Cargo Ship
    Safety Radio Certificate which is valid for a
    maximum of One year and must be renewed
    every year. Inspector/surveyors from
    appropriate shore-based authorities are
    entitled to inspect the ship station as often as
    they find necessary in order to ensure that it
    is in compliance with license conditions, and
    international conventions and agreements.
The master, or person in charge of the ship, has
the highest authority with regard to the
operation of the radio station. On board ships
fitted with GMDSS installations and sailing in
Sea Area A2, A3, A4, there must be at least One
person with a General Operator’s Certificate
(GOC).
Vessels sailing in Sea Area A1 – Restricted
Operator’s Certificate (ROC).
He holder of the radio license is required to
preserve the secrecy of telecommunications, as
laid down in the relevant provisions of the
convention. The station is not allowed to receive
any other correspondence than it is intended to.
Without special
permission, it is
prohibited to
publish or take
advantage of
traffic designated
to others.
Distress calls shall have absolute priority over
all other transmissions. All stations hearing
such calls shall immediately cease any
transmission capable of interfering with the
distress traffic and shall continue to listen to
the frequency used for the emission of the
distress call. This call shall not be addressed to
a particular station and acknowledgement of
receipt shall not be given before the distress
message which follows it has been transmitted.
All stations are forbidden to carry out:
a) Unnecessary transmissions
b) The transmission of superfluous signals and
    correspondence
c) The transmission of false or misleading
    signals
d) The transmission of signals without
    identification
The testing of radio equipment should be kept
at an absolute minimum. In order to avoid
harmful interference, remember to take all
possible precautions, such as:
-Choice of frequency (distress frequencies
should not be used unless absolutely necessary)
-Test should be carried out using reduced
power/artificial antenna
-Duration of test signals should be less than 10
seconds
-Test transmissions should include
callsign/other identification of the transmitting
station.
a)   The ship’s Radio License
b)   The radio operator’s certificates
c)   The GMDSS Radio Logbook
d)   The List of Call Signs and Station’s Numerical
     Identities used by the Maritime Mobile and
     Maritime Mobile service (ITU)
e)   The List of Coast Stations (ITU)
f)   The List of Ship Stations (ITU)
g)   The List of Radiodetermination and Special
     Service Stations (ITU)
h)   The manual for Use by the Maritime Mobile

In addition international/national regulations
    require than the following
    documentation/publications be carried on
    board:
a) Radio Safety Certificate
b) Antenna Sketch
c) List of Spare Parts
The Radio Log as required by the SOLAS
  convention, must be kept together with the
  radio and must be written in accordance with
  the details required by the Radio Regulations
  and Guidelines.
