Shortwave Bulletin is produced in Sweden,
but article contributions are normally presented in original language,
so you will find all Scandinavian languages as well as English/German in
this bulletin.
Quality is the key word. SWB's intention from the start was to
publish information of interest to the experienced DX-er. Nowadays most
of the interesting stations on the tropical bands are gone and shortwave
has changed a lot. SWB is now a forum for DX-information and is
published every second week. We welcome new active members.
To become a member of the mailing list: Contact the editor
and give us a short introduction.
Key benefits of being part of the mailing list is the guarantee
to receive the best and hottest DX news as fast and regularly as
possible. Your personal printed hard copy is normally produced and
mailed same day as deadline day! Within a few hours after deadline - a
pdf-version is already there for you in the mail.
HF Propagation
What do the figures mean: High solar flux (solar flux is expected to begin rising from 65 up to >200 when the next solar maximum is expected), 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
