Two QSOs this year, N5DY and AC2KK.  I confess the QSO with AC2KK may have employed a rubber clock...but I will assert this was totally within the spirit of SKN!

I used the classic Lionel J-38 of my wife, KB0QJJ.  N5DY was using a WW2 straight key, while AC2KK used a Czech Army key from the 1950s.
