The following part of the survey should always be performed by a fully qualified Radio Technician, using properly calibrated equipment, who has adequate knowledge of the Radio Regulations, the SOLAS Convention, as amended, and the IMO performance standards for radio equipment.

*	Check all that apply

This test equipment may also be used but is not mandatory.

Ships engaged on voyages in sea area A3 and A4 must use a combination of two methods (check all that apply)

HF radiocommunication equipment capable of operating narrow-band direct printing (NBDP) should be updated so that following the first radio survey after 1 January 2017, it meets the channelling arrangements reflected in sections II and III of part B in appendix 17 of the Radio Regulations.

The results of shore-based maintenance should be provided in the form of a shore-based maintenance report, a copy of which should be on board the vessel, and a label affixed to the exterior of the beacon detailing the name of the SBM provider and the date when the next shore-based maintenance is due. The SBM provider may affix a tamperproof seal or similar device on completion of the SBM. The maintenance interval, provided it does not exceed 5 years, may be aligned with the replacement date of the battery.

Per regulation V/12(g) and (h) of the GMDSS Amendments, for ships that are required to be fitted with radar installation(s), at least one radar installation shall be capable of operating in the 9 GHz frequency band from 1 February 1995.

A RDF is no longer required, as per 2000 SOLAS Amendments to Chapter V.
