As far as I know, it’s Rulhof’s second QSO using CW. His first QSO was with Arthur, ZS5DUV.
What is great is that Rulhof applied for his designated COOL PIN today and now has access to the most unique system in the world, The COOL.
Rulhof is now also the youngest radio amateur using the system.
Welcome too to The COOL CW Operators Club.
Well done Rulhof!
