Yugoslavia / Serbia (Zone 15):   YU1BCD was a radio club station that I worked frequently between 1974 and 1978 on CW.  All but one of those contacts was with Zoran who was very active on 80 through 10 meters.   Zoran is an avid contester and I have run across him many times in the major DX contests in recent years.  My first QSO with Zoran as YU7KW was in 1998 and the last one was in 2008.  I have worked Zoran on 80 through 10 metters.  All QSLs were received via the bureau.
