Spain - Special Prefixes for IARU Celebrations
The Secretary of State for Telecommunications and Digital Infrastructure has issued a new resolution temporarily authorizing the use of special call signs
by radio amateurs in Spain. This measure is being taken to commemorate the centenary of the founding of the International Amateur Radio Union (IARU),
of which the Spanish Amateur Radio Union (URE) is a prominent member, which will be commemorated this year, 2025.

The URE, as an official entity recognized by the Secretary of State, requested authorization to allow the use of special call signs during the period from
May 1 to 15, 2025. Within the framework of this celebration, all radio amateurs will be able to temporarily modify their call signs, maintaining their usual
suffix, but with a change to their district prefix and digit.

Details of the Resolution:
From May 1 to 15, 2025, holders of Spanish amateur radio authorizations are authorized to use special call signs, maintaining their call sign suffix and
modifying their district prefix and digit, as follows:

Prefix:
 * Call signs with the EAx prefix will use the AOx100 prefix.
 * Call signs with the EBx prefix will use the ANx100 prefix.
 * Badges with prefix ECx: will use the prefix AMx100.

 District:
 * The number 100 will be added to the corresponding district number.

Where "x" represents the district of the original call sign, with each of these special prefixes followed by the suffix assigned to the regular call sign.

Examples:
 * EA4ZZZ would become AO4100ZZZ
 * EB4ZZZ would become AN4100ZZZ
 * EC4ZZZ would become AM4100ZZZ

With this measure, the Secretariat of State strengthens its ties with the amateur radio community, celebrating the significant centenary of the IARU and
promoting participation and collaboration in telecommunications. It also recognizes the work of the IARU and radio amateurs in advancing communications
through the radio spectrum, thus offering an excellent opportunity to commemorate a century of history and unity in amateur radio.
