Radio club “Aco Vučković” sues three call signs for making contacts:
This is club’s base call sign. Many contacts were made using this call and it is well known to the hams.
This is club section call sign. Interesting story is that long time ago it was actually base call sign, bus somehow it switched places with YU1ABH.
This is club’s contest call sign. We use it in contest only and many great results were achieved. Previous contest call sign was YZ1U which had to be replaced as YZ is no more Serbian prefix.
