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.
HF Propagation
What do the figures mean in the table below: High solar flux (solar flux is expected to begin rising from 65 up to >200 when the next solar maximum is reached within 4-6 years), high A-Index (> 10), high K-index ( > 5) due to geomagnetic storms, also proton events and polar-cap absorption are bad news; giving poor long-distance reception of medium wave and tropical band stations, especially affecting paths over polar areas and paths east/west of your location. For instance Polar-cap absorption can completely wipe out signals in polar areas for several days.SWB - Shortwave Bulletin
