Station is now almost finished and close to final stage. Three rotary towers and two self-suporting towers are now loaded with most of antennas planed to be install.
The old one fixed tower for 15M stack is replaced with new one, 31m high, rotary, model 31/65, with two rings - on 10m and 24m. Now, tower 3 is carrying:
20M - 5/5 by M2

Rotary base is motorized with 1kW, 3 phase motor and controlled with RAC X rotor controller.
All installations of rotary towers is done by Simo, YT3M and I am very greatful for his huge and professional help. Without Simo, all could be harder and slower.
Also big thank to my godfather Lazo – YT0W who come twice with Simo to help in installation of last rotary tower.

Montenegro finally has got new prefix series. According to the ITU (take a look here ), Montenegro can use 4OA to 4OZ series, which gives 4O0, 4O1, 4O2, 4O3, 4O4, 4O5, 4O6, 4O7, 4O8 and 4O9 prefixes for ham radio usage. According to the W3UR's DX-Daily Bulettin , "When asked
exactly when the two nations need to complete this change a response
of 'as soon as possible" was given.'
At the same time, Serbia's prefixes 4N and YZ have been taken away and given back to ITU for future use to another nation. Prefixes for Serbia are now: YU and YT, both including all areas (0 to 9).
