The story of this callsign dates back to the mid-1990s, at the time I was active member of the Sofia University radio club LZ1KBB, back-then led by LZ3FN and LZ4AX. The callsign was temporarily assigned to the radio club (there are no permanent assignments for short calls in LZ) and we had a great time playing contests with it! As the club became inactive since LZ4AX moved to USA and LZ3FN - to the other side of LZ the callsign was released which in turn made it possible for me to apply for it. Nowadays I am (usually) the one behind it during major contests.
The page here is dedicated to track the progress of my station located 20km east from the city I live in - Sofia. At some point in the future there should be plenty of technical information here, HI!
