Leader in Friendship
First recipient · Radioamateri magazineHundreds of international awards recognized technical achievement. But in 2003, the magazine Radioamateri created a recognition that had never been awarded before — instead of honoring technical excellence, it honored something much rarer: friendship.
Venci Ristov became the first recipient of the Leader in Friendship diploma, for exceptional contribution to popularizing new technologies among radio amateurs and people around the world.
It's the same instinct that shaped everything that came after: log it, confirm it, keep the record. A QSL card proves a contact happened. This diploma proves something else happened — that people noticed how he showed up, not just what he built. Two decades later, that same idea — verified, not just claimed — became the foundation of AI World Records.
Even after hundreds of international awards, this remains the recognition he values the most.
