Sissiradistikilta is a special training branch guild for Finnish sissiradisti trained troops. The Sissiradistikilta Guild was founded in 2017, centenary of independent Finland, and OI6S is the callsign of its military amateur radio club station. Based in Jyväskylä, Finland, the guild is active within the whole country. Amateur radio activity, operations, and locations vary.
More information on the OI6S home page.
About the OI prefix
The OI prefix is quite rare as only under 30 stations with the prefix exist.
As it's said on the website:
The prefix ”OI” is reserved for Finnish military amateur radio, i.e. ham radio operation happening within or in ties to Finnish Defence Forces or its tradition.
It might be worth mentioning that military amateur radio operation is normal amateur radio activity and amateur radio is not specifically used to pursue any military goals. That said, we operate according to globally accepted rules and recommendations and promote good operating practices and ham spirit.
OI award
A special award is available for working ham radio stations with the OI prefix. Five (5) contacts are needed for the award if the applicant's station is located outside of Finland. For further information, see Sissiradistikilta's web page: sirad.fi/oi-award/.
