WRC-2003 Revises Call Sign Formation At World Radiocommunication Conference 2003 held in Geneva, Switzerland, 9 June to 4 July, 2003, two principal revisions were made to the ITU Radio Regulations concerning the formation of call signs in the Amateur Services. Thus call signs such as 9M2MSIA, 9M2IARU, 9M2P27U and 9M200AA now will be permitted. The prohibition against prefixes of amateur station call signs commencing with a digit when the second character is the letter O or the letter I, has been removed.

Apa pula kata Guideline on the Allocation of Call Sign to the Amateur Radio Service yang dikeluarkan oleh MCMC pada 29 Disember 2003? Mari kita lihat kandungannya.
The intent of this document is to guide staff of the Malaysian Communications and Multimedia Commission (MCMC) and to inform interested parties on the allocation of call sign to the Amateur Radio Service; to ensure efficient allocation of resources in compliance with the Communications and Multimedia Act 1998
and the requirement of the International Telecommunication Union (ITU).
INTRODUCTION
1. All radiocommunication transmissions shall be capable of being identified by identification signals or by other means. For a radiocommunication station that is opened to the international public correspondence and capable of causing harmful interference beyond its national boundary as in the case of the Amateur Radio Service; the station shall carry a call sign in conformity with the International Call Sign Series allocated to the administration by the ITU. The ITU clearly defines the formation of call signs for the Amateur Radio Service in Article 19 of the Radio Regulations.
2. This Guideline describes the formation and allocation of call sign to the Amateur Radio Service station in Malaysia.
Ok tepat sekali dan selari dengan ITU Radio Regulations, Article 19 (Identification of Stations) Section III - Formation of call signs. Adalah menjadi harapan agar perlaksanaannya selari dengan garis panduan yang telah dikeluarkan.
