On the occasion of the 75th anniversary of our UBA, more than 60 stations with the special ON75 prefix will be on the air during the months of January and February. Naturally, the UBA invites all amateurs worldwide to participate.
In the meantime the event has also received international publicity. From your cosy shack you will not only be able to hunt for these special stations: no less than eleven different certificates in two categories will be offered. You can read all about these certificates here.
