This first NA station opens my new season and my Rx Challenge. The goal is to spot (Rx) the greatest number of UNIQUE CALLSIGN of North American station (W and VE). The previous season I had reached the number of 39 unique callsign. I'm using the same antenna system (2x Wellbrook ALA100 loop) and wires configuration for the new period.
It is an personal challenge but every one can play the game and give some animation in this great band. I hope to see many new incomers from NA area.
Good luck to all, Patrick
