Sissiradistikilta is a special training branch guild for Finnish Defence Forces sissiradisti trained troops. The Sissiradistikilta Guild was founded in 2017, the centenary of independent Finland.
Sissi units’ main task is to perform reconnaissance and intelligence operations. Although many times dubbed as ”guerrilla units” due to the tactics they sometimes use, sissi troops are a regular part of the Finnish Defence Forces and nowadays the term is mostly used to mean reconnaissance units.
Sissiradisti, which meaning mostly corresponds to the concept of reconnaissance radio operator, is the name for specially trained signalists within these troops, and as so, some of the Guild members have interest towards amateur radio.
The OI6S radio station
OI6S is the callsign of the amateur radio (”ham”) station of the Guild Sissiradistikilta. The operating location and activity of the station vary.
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. There is a nice award available for those who have worked a sufficient number of stations with the OI prefix.
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.
