    The Radio Society of Sri Lanka (RSSL) education portal, hosted at edu.rssl.lk, is a nationwide digital initiative dedicated to youth empowerment, STEM education, and skill development. Moving beyond traditional study tracks, this platform directly supports Scouts, Guides, and university students across Sri Lanka in mastering telecommunications and earning official proficiency badges.
     
    Our History
     
    Founded on July 1, 1950, as the Radio Society of Ceylon, the organization was renamed the Radio Society of Sri Lanka in 1974. As a member of the International Amateur Radio Union (IARU), RSSL has spent over seven decades representing licensed radio amateurs, building disaster communications networks, and mentoring youth. From classic field operations like Jamboree on the Air (JOTA) to helping the Sri Lanka Girl Guides Association secure their official radio club license (4S7GGA), RSSL remains at the forefront of non-formal technical education. 
     
    The National Proficiency Badge Initiative
     
    The edu.rssl.lk portal serves as a central learning hub to make radio technology accessible to youth organizations and higher education institutes nationwide.
    • Scout & Guide Badges: Comprehensive course paths specifically tailored to fulfill the official requirements for badges like Signaler, Leading Signaler, Wireless Man, and Radio Mechanic.
    • University STEM & Engineering: Advanced modules designed for undergraduate engineering students to bridge university theory with practical RF communication, Software-Defined Radio (SDR), and satellite tracking. 
    • Hands-on Training Workshops: A blend of digital modules and practical field training, covering transceiver operation, simplex frequencies, emergency communications, and signal etiquette. 
    • National Licensing Pathways: Structured guidance to help young leaders progress from their organization's internal proficiency badges directly toward the official Telecommunications Regulatory Commission of Sri Lanka (TRCSL) Radio Amateur Examination.

Available courses

Scouts: SK-1 Radio Mechanic

Welcome to the Radio Mechanic badge course!

 

This is the senior wireless badge. The JK-1 Wireless Man course is the perfect foundation, and here we go deeper: how radio actually works from microphone to speaker, why each wave band behaves the way it does, how to read and draw schematics, and what happens inside transistors, chips and amplifiers.

 

The badge has two parts:

  •  💻 Online (this course): theory lessons + the Final Theory Exam (80% to pass, 2 attempts, best counts) 
  • 🤝 In person: the practical day: assemble a receiver in temporary form, draw its circuit diagram with correct symbols, solder cleanly, and explain the theory at the bench

 

Questions? Ask your troop leader or contact the RSSL examiner team.

Scouts: SA-4 Leading Signaller

Welcome to the Leading Signaller badge course!

 

This is the senior signalling badge. Everything from the JA-4 Signaller course is assumed knowledge, so revise it first if anything feels rusty. Here the focus is speed, accuracy under pressure, improvisation, and leading communications for others.  

 

The badge has two parts:

  •  💻 Online (this course): theory lessons + the Final Theory Exam (80% to pass, 2 attempts, best counts)
  •  🤝 In person: the practical day: 150 letters at rate 9, buzzer at rate 8, lamp at rate 6, two improvised methods over ½ km, all at 90% accuracy

 

 

Questions? Ask your troop leader or contact the RSSL examiner team.

Scouts: JA-4 Signaller

 

Welcome to the Signaller badge course!

 

You are about to learn skills that have saved lives for over a century: sending clear messages by flag, light, sound and radio. Work through the lessons in order. Each one ends with a recap card that is perfect for revision. When all six are complete, the Final Theory Exam unlocks.  

 

The badge has two parts:

  • 💻 Online (this course): theory lessons + the Final Theory Exam (80% to pass, 2 attempts, best counts)
  • 🤝 In person: the practical day with the RSSL examiner: semaphore, Morse, radio procedure and battery drill

 

The badge offers two paths (flag/Morse signalling, or radio communication). This course prepares you for both, so you can choose your strongest path on the practical day.

 

Questions? Ask your troop leader or contact the RSSL examiner team. 

Scouts: JK-1 Wireless Man

Welcome to the Wireless Man badge course!

You're about to learn the science behind every radio, speaker and Bluetooth gadget you've ever used. Work through the lessons in order — each one ends with a recap card that's perfect for revision. When all six are complete, the Final Theory Exam unlocks.

The badge has two parts:

  • 💻 Online (this course): theory lessons + the Final Theory Exam (80% to pass)
  • 🤝 In person: the practical day — building, soldering, wiring and demonstrating with the RSSL examiner

Questions? Ask your troop leader or contact the RSSL examiner team.

Objective: - Demonstrate basic knowledge in wireless technology

  1. Connect a wireless receiver to its external connections including aerial, earth and power supply. Know the safety precautions necessary with mains etc.

  2. Construct a very simple wireless receiver and tune it to a local broad casting station or other transmitter, signals receivable on head phones or loud speaker. Kits may be used.

  3. Soft solder a joint between two copper wires smaller than 16SWG.

  4. Run neatly the wiring for an extension loud speaker from one room to another and ensure that both loud speakers operate simultaneously satisfactorily.

  5. Know what Blue Tooth technology is. Use this technology to communicate a message from one room to another using a mobile phone and a Bluetooth speaker/another phone..
