The first and only private and commercial shortwave station in Scandinavia
Getting started - 10 founding members: DX-listeners, radio-amateurs, CB-operators, Free Radio -operators, scanner listeners - 10 months for planning and preparations: collecting money, applying license, building (studio, transmitter, station, etc.) - First transmission on 25 meter band - First transmission on 48 meter band - First transmission on medium waves - 13 members at the moment (+ support members)
Broadcasting - SWR broadcasts every 1st Saturday of the month and some special occasions like X-mas - Every now and then SWR also sell airtime for other radio hobby groups - Frequencies on 25 mb: and kHz - Frequencies on 48 mb: 5980 and 6170 kHz -On medium waves 1602 kHz
Behind the station - The stations is operated by the association "Vaihtoehtoisen radiotoiminnan tukiyhdistys ry" (The support association for alternative broadcasting) - 13 members and 5-10 "supporting" members
Broadcasting on 48 meters 48 meters band is for "local" broadcasts. On 48 meters it is possible to receive our signal almost anywhere in Finland, but only during daylight hours. In the night time the signal "jumps" abroad.
Broadcasting on 25 meters 25 meters band is so called DX-band. On the 25 meters the signal is stronger in Central-Europe and Scandinavia than in Finland. Sometimes when solar activity and propagation is favourable, it might be possible to listen us also in USA and Canada.
Broadcasting on Medium waves Medium wave band is for "local" broadcasts. At the time of day light, signal is possible to hear almost anywhere in Finland. In the night time the signal "jumps" abroad and the others station on the same frequency cause interferences.

Happenings at the station
Future plans... - New Jingles - More broadcasting power - Good programs… - A lot of maintenance work
Recently completed projects: - New antenna mast for MW, the BIG one… - Some improvements in studio - Big transmitters under the testing - ……….
How to listen shortwaves... - Some kind of "world band" or "communication" receiver needed, because from the normal radio you don’t usually find any shortwave broadcasting bands - Sometimes if "space weather" is favorable, old tube or kitchen radio might be good enough. - External antenna is highly recommended: example 12 meter copper-wire outside from window -Time of day affect to reception very strongly More information from or (Suomen DX-liitto)
How to listen medium waves... - Turn on you receiver and switch it to AM(MW) mode and select 1602kHz. - Rotate your radio 360 deg to find best possible reception. -External antenna is highly recommended if there is a connector to external antenna in receiver (example meter copper-wire outside from window) - Time of day affect to reception very strongly - Cement and metal walls attenuate the signal More information from or (Suomen DX-liitto) Due to internal antenna, position of the receiver have a influence to quality of the reception.
What you can do with us and for us? -Have your own air time and program content using the SWR studios and equipment - If you have enough imagination and graphical skills you can help us by making QSL card designs for us. (QSL card = Verification card for our listeners) - Audio material like station announcement, full ID's or just a start and end effects to announcements.
