Shortwave Bulletin is produced in Sweden basically in Swedish, but contributions are normally presented in original language, so you will find all Scandinavian languages as well as English in this bulletin.

Quality is the key word. SWB publish information of interest to the experienced DX-er. This is not a forum for the newcomer to shortwave. SWB is published every second week. We welcome new active members.

To achieve membership: Contact the editor and give us a short introduction. The SWB board has the right to accept or turn down applications for membership.

Key benefits of the membership is the guarantee to receive the best and hottest DX news as fast and regularly as possible. Your personal printed hard copy is produced and mailed same day as deadline day! Within a few hours after deadline (normally 0800 UTC Sundays) - a pdf-version is already there for you in the mail.
