As an amateur radio operator and proud member of the Radio Society of Sri Lanka, I had the great opportunity to support the JOTA–JOTI 2025 event held at Panadura Sumangala College. Our station operated under the call sign 4S7ICT, with my own call sign 4S6RNL joining the team.

Over 350 enthusiastic scouts participated in this wonderful event, connecting with fellow scouts across the world through the magic of radio communication. Special thanks to Chanaka (4S7ICT) for dedicating his time, equipment, and expertise to guide the young scouts, and to SWLs Buddila and Thevhan for their valuable assistance.

For those who are new — JOTA (Jamboree On The Air) and JOTI (Jamboree On The Internet) are annual global scouting events where scouts communicate and share experiences using amateur radio and online platforms. It’s all about building friendship, learning communication skills, and exploring technology.

A heartfelt thank you to everyone who supported and participated — your efforts made this event a great success!

What is the HVAC System

An HVAC system stands for Heating, Ventilation, and Air Conditioning and is a network of equipment and technologies that regulate a building's indoor temperature, humidity, and air quality to provide thermal comfort and a healthy environment. HVAC systems use components like furnaces, boilers, air conditioners, and ductwork to deliver heated or cooled air, exchange stale indoor air with fresh outdoor air, and filter out pollutants.
