ES100 prefixes will mark the 100th birthday of the Estonian Republic.
The «ES100 Project» encourages worldwide hams to chase 15 different
ES100 callsigns on the air. The http://es100.eu website is «still a bit under construction» but should be ready within a week. They will be active starting February 1 and continue to March 31. Each QSO counts two points for European stations and four points each for non-European stations, with three award levels, bronze for 50 points, silver for 75 points and gold for 100 points. The «Leaderboard TOP10» will get a special award. Wooden plaques will be available to order. All of these and QSLs can be requested from the webpage when it’s ready. There will also be LoTW and eQSL confirmation available. They will not be collecting QSL cards from those they work, so «No need to send them to our bureau,» they say.
