Çështje të pajtueshmërisë Elektromagnetike dhe spektrit të Radios (ERM); Karakteristikat teknike dhe metodat e matjes për marrësit e montuar në bordin e anijes për marrjen e Thirrjes Dixhitale Selektive (DSC) në bandat detar të MF, MF/HF dhe VHF

Electromagnetic compatibility and Radio spectrum Matters (ERM); Technical characteristics and methods of measurement for shipborne watchkeeping receivers for reception of Digital Selective Calling (DSC) in the maritime MF, MF/HF and VHF bands

Scope

The present document states the minimum operational and performance requirements for shipborne receivers intended
to be connected to an external installation, including a decoder for DSC, and used as receivers for watchkeeping DSC
on board ships operating in the mobile MF, MF/HF and VHF band allocated in the ITU Radio Regulations [1] to the
maritime mobile service, both in connection with distress and safety communication and in connection with general
communication.
These requirements include the relevant provisions of the ITU Radio Regulations [1], Recommendation ITU-Rs
M.493-13 [3], M.541-9 [9] and the IMO Resolutions A.803 (19) [i.5], A.804 (19) [i.6], A.806 (19) [i.7] and
A.694 (17) [i.4].
The present document specifies also technical characteristics, methods of testing and required test results for dedicated
watchkeeping receivers for use with radio installations in the GMDSS as required by chapter IV of the SOLAS [i.8].
DSC watchkeeping receivers may be a separate equipment or be integrated with a DSC or radiotelephone equipment.
For integrated equipment the present document specifies the requirements and methods of testing of the DSC
watchkeeping receivers only.
DSC watchkeeping receivers can be either fixed-frequency receivers or, in MF/HF bands, scanning receivers.
Requirements for the DSC equipment or radiotelephone equipment are given in EN 300 338-2 [10], EN 301 925 [i.1]
and EN 300 373-1 [i.3] respectively.
