Stockholm street scene

The Swedish Amateur Radio Society, SSA, will celebrate its 100-year anniversary on September 10, 2025, with a special award activity. Beginning September 10 through October 12, SSA will feature a diploma activity that involves contacting SSA’s anniversary stations on as many of the 160 – 6-meter bands and modes as possible. There will be 10 special call signs on the air: SB100SSA, SC100SSA, SD100SSA, SE100SSA, SF100SSA, SH100SSA, SI100SSA, SM100SSA, 7S100SSA and 8S100SSA.

SSA will use the Hamaward online logging system, allowing hunters to track their progress in real time and download their diplomas and eQSLs instantly. The same stations will also participate in the Scandinavian Activity Contest (SAC) this coming autumn.
