LZ DX competition 2025

LZ DX Contest is one of the most popular November amateur radio contests and attracts operators from all over the world. The organizer is Bulgarian Federation of Radio Amateurs (BFRA), ktorá tento prestížny závod pripravuje s dôrazom na férové podmienky, technickú presnosť a vysokú úroveň logovacej disciplíny.
