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/.
