Departure from Bol, Croatia - Loss of radar separation, incident report, radio communication failure

We are departing Brač airport on a day with the most perfect weather you can ask for, but outside of Air Traffic Control(ATS) operating hours. We take off on runway 21 to the scenic, South-West direction, with fantastic view of Bol village, its beaches, and the surrounding high rocks. Meanwhile another airplane, reporting itself southwest from the airport at D3 point, made a straight in approach to runway 03 from the opposite direction. We were separated by 2 nautical miles and I was still in uncontrolled airspace, but Split RADAR got an alarm on their radar screen and had to file a collision risk report. And the excitements were not over yet, just before entering Sarajevo APPROACH controlled airspace in Bosnia, my radio stopped transmitting. We were given a clearance to continue as planned, and finally the problem was solved.
