The place is called Obosnik, a hilltop at the entrance to the Bay of Kotor in Montenegro. Montenegro means Black Mountain and this tiny republic is mountainous, however the mountains are black only when silhouetted by the setting sun. At daytime this country is extremely attractive, The Bay of Kotor itself is regarded as World Heritage by the UNESCO and every day thousands of tourists pass the landmark of Montenegro, viz. the station of Ranko Boca, 4O3A on Obosnik.

This place had been used solely as a military observation post and a radar site before Ranko moved in next door sometime at the end of the 1990s. At that time he was still signing YT6A as Montenegro was united with Serbia.

Ranko was born in 1960 and became member of the local radio club in 1975. Pretty soon he discovered the fun of contesting. Received his first license in 1980 but still, most often, took part in competitions from club stations. The art of radiosport was very popular in Yugoslavia. In early 1990s the Balkan war broke out and the result of it was a division of the federation. A few new independent countries - and new DXCC entities, or contest multipliers - were born. However, it was first in 2006 that Montenegro dissolved its union with Serbia and received the 4O prefix from the ITU. Ranko became overnight a wanted man. He already had an advanced station and excellent skills as operator, so 4O quickly disappeared from the Most Wanted List. Since the independence more than 550 thousand contacts have been logged at 4O3A, and they all are uploaded to the Log of The World. The station is active almost every day and on weekends the activity is obviously increased. The station is open to visitors and plenty of excellent operators, and plain visitors like me, have been here.

Expanding the antenna farm is an ongoing process. I did not count the antennas, they are too many and too high. More details are surely to be found on Ranko's web at www.4o3a.com When I dropped in, or rather managed to slowly climb to 2000 ft, a few guys were working on a new 7 MHz rotary antenna. It was a weekend in September 2013, a month before the CQ WW SSB. Ranko plans to do a Single Operator battle in this contest. I'll try to give him a shout then.

Inside the radio room, the equipment is under protective covers because of drilling in the walls. From left:- tired Bore, 4O6Z, technician Bojan, Ranko,403A, Snezana, 4O4W, and Dragan, 4O4A.

Ranko flies back home in a small helicopter together with Marko, 4O9TT, saving a lot of time, as the road up to top is still difficult and long.
