In 2018 the month of May saw the 80th anniversary of The First Class CW Operators Club, FOC. During the month the club had various special calls on the bands during an activity challenge run by the club.
I was able to arrange the call GB80FOC and had the pleasure of activating it for 4 days during the month. I contributed 1392 QSOs to the overall log.
The QSL route for GB80FOC is via G3SWH. Please see Phil’s website for instructions.
