This date marks the anniversary of the founding of the International Amateur Radio Union (IARU), the global organization representing amateur radio (wireless) interests amateur roof organization.

On this day, declared in memory of the IARU’s establishment on April 18, 1925 Paris, the history, current status, and societal contributions of amateur radio are highlighted. On this occasion, amateur radio operators strengthen camaraderie by communicating with fellow operators across the globe and raise public awareness of the benefits of this hobby.

History of April 18 World Amateur Radio Day

The primary reason April 18 was chosen as World Amateur Radio Day is that on this date in 1925, the International Amateur Radio Union (IARU) was founded. The IARU, the first international organization for amateur radio, was established in Paris on April 18, 1925, with American radio amateur Hiram Percy Maxim elected as its first president. This important development brought together radio amateurs worldwide under a single umbrella, and since then, April 18 has become a day of celebration for all amateur radio operators. Each year, the IARU selects a theme or motto for this special day to draw attention to specific topics.

For example, in 2023, the theme for World Amateur Radio Day was “Safety for All,” emphasizing the role of amateur radio operators in public safety.

As of today, the IARU has reached its 100th anniversary, and the 2025 World Amateur Radio Day events are being organized around the theme of celebrating the union’s centennial legacy.

Ways This Day Is Celebrated

World Amateur Radio Day is celebrated by amateur radio operators through various events at both local and international levels. Generally, on this day, amateur radio operators take to the airwaves and strive to make as many radio contacts (QSOs) as possible worldwide, spreading the spirit of amateur radio. Many radio clubs and associations organize special gatherings, seminars, or workshops to bring their members together and conduct public outreach.

Some amateur radio associations also seek official proclamations from local governments to recognize the day and increase public awareness.

• Special call signs and activities: Many amateurs worldwide use special call signs for this occasion and conduct commemorative radio contacts. In Türkiye, the All Amateur Radio Operators Association (TAMAD) organized events in 2025 under the special call sign TC100WARD to mark the IARU’s 100th anniversary. Through this special station, connections were established with amateurs globally and technical knowledge was exchanged.
• Club gatherings: Radio amateurs gather at club centers or in the field to set up equipment together and celebrate World Amateur Radio Day through hands-on practice. For example, TAMAD invited all amateurs to an event at its headquarters on April 19, 2025. Similarly, TRAC and other local clubs meet with their members to share the significance of the day and pass on experience to new operators.
• Promotion and awareness: This special day provides an opportunity to highlight not only the hobby aspect of amateur radio but also its valuable contributions to society. Radio amateurs introduce the hobby to friends and family, share their experiences on social media using hashtags such as #WorldAmateurRadioDay, and encourage potential new participants. Additionally, some local radio stations and media outlets broadcast news and programs about amateur radio on April 18 to inform the public.

Amateur Radio/Wireless

Amateur radio (amateur wireless) is a communication service based on individuals engaging in radio communication for personal interest and curiosity, without commercial intent, and gaining technical experience. The International Telecommunication Union (ITU) defines the “Amateur Radio Service” as an experimental communication activity that allows individuals to develop their knowledge in communication and electronics, with no political or commercial purpose.

The term “amateur” here does not imply any lack of skill; rather, it emphasizes that this activity is a passion-driven pursuit, carried out without any expectation of financial gain.

Amateur radio operators acquire the authority to communicate on assigned frequency bands after passing required examinations and obtaining licenses. It is estimated that approximately three million licensed amateur radio operators exist worldwide. These individuals use various communication methods across HF (short wave), VHF (Very High Frequency), and UHF (Ultra High Frequency) such as frequency bands, including digital (digital) modes.

Amateur radio activities span a wide range, from making contact with a station in the neighborhood using a simple handheld radio, to satellite communication or transmitting intercontinental radio signals. Through these activities, amateur radio operators enhance their technical knowledge, contribute to testing new communication technologies, and build bridges with people across the globe.

Indeed, amateur radio is also described as an endeavor that fosters international goodwill. Amateurs from different countries create a transnational culture of friendship and solidarity through radio waves, gaining opportunities to understand and appreciate each other’s cultures.

Social Importance of Amateur Radio

Amateur radio has a critical societal function beyond being a hobby. Especially during disasters and emergencies, when professional communication infrastructure fails or becomes overwhelmed, amateur radio operators step in to ensure uninterrupted communication. Viewed historically, amateur operators have provided vital communication support during disasters since the earliest days of radio communication, and this contribution remains life-saving today. In major disasters that render advanced communication technologies inoperative due to power outages, network collapse, or other causes, “when all else fails, amateur radio works” has proven true, as amateur radio operators become the most reliable communication source in the earliest hours.

For this reason, amateur radio is often described by the phrase: “When all else fails, ham radio works.”

In Türkiye, amateur radio operators play a vital role as a backup communication force during disasters. The largest organization of amateur radio operators in the country, the Türkiye Radio Amateurs Association (TRAC), is officially recognized as a support partner under the Türkiye Disaster Response Plan (TAMP).

From the earliest moments of disasters such as earthquake, hello, landslide, and forest fires, TRAC establishes its own communication infrastructure on-site using volunteer operators and supports the communication needs of public institutions.

Another important societal aspect of amateur radio is its human resource and educational dimension. Individuals engaged in this hobby develop technical expertise and practical skills while also cultivating a sense of responsibility to serve society. The presence of trained volunteer communicators ready to respond during disasters is a crucial factor in enhancing community resilience.

Moreover, amateur radio activities can inspire young people to develop interest in technology and guide them toward careers in communication, electronics, and engineering. In this regard, amateur radio is also viewed as a STEM (Science, Technology, Engineering, Mathematics) education stepping stone and a citizen science initiative.

Amateur Radio Activities in Türkiye

In Türkiye, amateur radio activities are organized through various associations and clubs. The oldest and most extensive of these organizations is the Türkiye Radio Amateurs Association (TRAC). Founded in 1962 by Dr. Bedii Ezgi and colleagues, TRAC has led the development of amateur radio in the country and has been the sole authorized representative of Türkiye within the IARU since 1965. In 1991, TRAC was granted the status of a public benefit association by a decision of the Council of Ministers and has since been dedicated to defending the rights and interests of amateurs at both national and international levels. TRAC currently serves a community of nearly 40,000 licensed amateur radio operators through 69 provincial and district branches and over 3,000 members nationwide.

In addition to TRAC, other amateur radio associations operate in various provinces and regions. For example, the All Amateur Radio Operators Association (TAMAD) is one of the active organizations in this field. Founded in 2015, TAMAD organizes events primarily in Istanbul and its surroundings, contributing to the training of new amateur operators through educational seminars and exam preparation programs.

TAMAD promotes Türkiye internationally during global events such as World Amateur Radio Day by using special call signs and strengthening friendships with amateurs worldwide. For instance, TAMAD’s TC100WARD special station successfully represented Türkiye in 2025 by establishing contact with hundreds of amateurs during the IARU’s centennial celebrations.

In addition, amateur radio clubs within universities (such as those at technical universities) and local amateur groups also exist. These clubs conduct promotional activities within their communities and carry out educational initiatives to increase youth interest in amateur radio.

Another dimension of amateur radio activities in Türkiye is licensing examinations and regulations. To become a licensed amateur radio operator, individuals must pass periodic examinations conducted by the General Directorate of Coastal Safety under the Ministry of Transport and Infrastructure (KEGM).

Associations such as TRAC and TAMAD provide candidates with educational materials for these exams and offer support regarding exam questions and practical applications. Those who successfully obtain their licenses may join associations, participate in joint activities, enroll in emergency communication training, and represent Türkiye in national and international competitions.

April 18 World Amateur Radio Day once again brings attention to the importance of amateur radio both globally and in Türkiye. On this traditional day, radio amateurs reflect on their heritage, share their experiences, and celebrate new technologies and friendships.
