More than a radio club. A place where knowledge moves forward.
Since 1946, we have brought together people who see radio as more than a hobby.
About the club
E74BYZ brings together generations of radio amateurs who share knowledge, build infrastructure and pass their experience on to new members — from a first callsign to field operation and modern digital networks.
1946
A club with decades of unbroken amateur-radio practice — people, knowledge and the same call into the ether. Generations keep meeting here, and the curiosity for radio does not fade.
E74BYZ
The club identity on the air — used in contests, field work, infrastructure and everyday traffic. Behind the callsign stands the station, the operators and the work of the club.
Education
Through education and practical work the club prepares new radio amateurs — from first lessons and workshops to the exam and a personal callsign. Mentors pass on knowledge until candidates are ready for the air.
Infrastructure
Analog and digital repeaters, Meshtastic and the Čemernica site — infrastructure the club builds and maintains so the region stays connected beyond a single station.
Club space
These are the club rooms and headquarters of Radio Club Nikola Tesla — every Thursday at 19:00 the doors are open to anyone interested.
The direction we work in
We preserve and develop amateur radio through knowledge, practical work and modern communication technologies, creating a place where new generations can learn, explore and build.
Our mission is to develop and promote amateur radio, pass on technical knowledge and create conditions for practical learning, experimentation and work with radio-communication technologies. Through training, shared projects and field activities we connect the experience of current members with new generations of radio amateurs.
Our vision is a modern and open radio club that preserves the tradition of amateur radio while following the development of new technologies. We want to be a place for gathering, learning and technical creation, and a reliable partner to the local community, educational institutions and services for which radio communications can matter.
What we do
From the first contact with radio technology to field work and building our own communication infrastructure — club activities connect knowledge, experimentation and practical work.
Training for amateur-radio operators, practical workshops and passing technical knowledge on to new generations.
Analogue and digital communication, shortwave, VHF/UHF systems and everyday amateur-radio operation.
Participation in domestic and international amateur-radio contests, from the club station to operating in the field.
Portable radio, activations from mountains and protected areas, testing equipment and making contacts outside the club station.
Building and maintaining repeater, analogue and digital systems that connect radio amateurs across a wider area.
LoRa, Meshtastic and new communication systems through which we explore the possibilities of modern radio technologies.
Cooperation and community
Our work goes beyond the amateur-radio hobby. Through cooperation with the City of Banja Luka, civil-protection services and the academic community, we connect technical knowledge and communication infrastructure with real needs of society.
By the mayor’s decision, Radio Club Nikola Tesla was included among organisations whose technical, material and human capacities can contribute to the protection and rescue system of the City of Banja Luka.
