Q: Leonard, it’s wonderful to have you here today. Could you tell our readers about your journey into the world of ham radio?

Leo, 4S7LF/OZ6ZV: Certainly, and it’s a pleasure to be here. My introduction to ham radio was rather serendipitous. As a young schoolboy, I was captivated by electronics, and observing my relatives constructing various radio receivers left me curious. They weren’t high-tech, superheterodyne receivers; they were simple yet intriguing.

Q: So, what was the turning point in your ham radio journey?

Leo, 4S7LF/OZ6ZV: Well, I was boarding at my aunt’s place in Moratu Mulla, walking to St. Sebastian’s College in Moratuwa daily. On my way, I noticed a house adorned with wire antennas, and I couldn’t help but wonder what it was all about. Later, I discovered it belonged to a Radio Amateur, Ernie Perera, with the callsign 4S7EP (then VS7EP). My curiosity led me to visit his station, and it marked my first encounter with an amateur radio setup.

Q: It seems like that was the start of something big.

Leo, 4S7LF/OZ6ZV: You’re absolutely right. Though I had some domestic challenges in my early years, my determination led me to an opportunity at the Ceylon Army Signal Corps. Despite being just a schoolboy, I applied for a position and was eventually selected. The training was tough, including weapon training, but I completed it and was even promoted to Corporal for my skills in servicing military communication equipment.

Q: Impressive! So, how did your transition to ham radio take place?

Leo, 4S7LF/OZ6ZV: My journey into ham radio took a significant turn when I joined Civil Aviation as a technician. It was during this time that I met Mr. Dick Lemercier, 4S7LM, who introduced me to the world of ham radio. I began as a Short Wave listener, but it wasn’t long before I bought my first receiver and became an active participant.

Q: It sounds like you had quite an adventurous path. Any standout experiences?

Leo, 4S7LF/OZ6ZV: Indeed, one memorable experience was my involvement in fox hunting with the Aviation Team in Mirigama, sponsored by Mr. John Amarathunga, 4S7JA. During my time in aviation, I had the opportunity to work with high-power transmitting equipment, navigational tools, and more.

Q: It’s fascinating how ham radio weaves its way into our lives. Anything else you’d like to share?

Leo, 4S7LF/OZ6ZV: Absolutely. I must say that ham radio played a pivotal role in helping me secure a job in Denmark. It was during my time in Denmark that I was introduced to a fantastic group of Danish hams and found a close friend named Kim, OZ8TU. His support not only advanced my career but also solidified a lifelong friendship.

Q: Any special achievements or memories related to ham radio?

Leo, 4S7LF/OZ6ZV: Well, during my time in Denmark, I served as a committee member in the local ham club in southern Denmark. This connection led to my involvement in obtaining the Piduruthalagala repeater for Sri Lankan hams, a story of international friendship and cooperation.


My contacts in Sri Lanka, including Shanthi 4S7WP and Sena 4S6SSP, had a specific request for a crystal (Xtal) for a Pye repeater in Sri Lanka. I reached out to my friend Allen, who was working at TP Radio in Denmark. Instead of just a crystal, he offered an entire repeater as a gesture of friendship. This generous act resulted in a significant milestone in Sri Lanka’s ham radio history.

Ham radio has been a guiding light throughout my life, connecting me with people, places, and experiences that have shaped who I am today. It’s a reminder that curiosity and a passion for learning can open doors and create connections that transcend boundaries.
