Montenegro finally has a callsign prefix block. Montenegro gained
independence in late June 2006 and had been using the following
prefixes: 4O3, 4O6, YT3, YT6, YU3, YU6, YZ3 and YZ6. The
International Telecommunications Union did not want to give the new
country a new prefix and required the states of Montenegro and Serbia
to agree upon one or two prefixes of the five (4N, 4O, YT, YU, YZ)
from the former Serbia/Montenegro country. On May 11th an agreement
was made and the ITU now lists the 4O (Four Oscar) prefix as belonging
to Montenegro. So Montenegro can use 4O0 (Four Oscar Zero) through
4O9 (Four Oscar Nine). Serbia will continue to use the YT and YU
prefixes. This will include all call areas (0-9) for each. However
the 4N and YZ prefixes have been taken away and given back to the ITU
for future use to another nation. This was confirmed today by a
spokesman from the ITU's Radiocommunication Sector. When asked
exactly when the two nations need to complete this change a response
of "as soon as possible" was given. So there may be a short period of
time to complete the switch over. DXers need to update their logging
software, carefully!
Serbia: YT0, YT1, YT2, YT3, YT4, YT5, YT6, YT7, YT8, YT9, YU0, YU1,
YU2, YU3, YU4, YU5, YU6, YU7, YU8 and YU9
Montenegro: 4O0, 4O1, 4O2, 4O3, 4O4, 4O5, 4O6, 4O7, 4O8, 4O9
