  CIS15431992-11-15"The following is adapted from information provided by NT2X via G0CGL: A proposal has been submitted to the
ITU by one of the administrative units responsible for such matters (known as RSS), without any consultation
with amateurs of respective CIS countries. The proposal rather reflects the desire to allocate call sign blocks for
their professional communications services and hams had no say in the matter. As a result, 95% of all
Ukrainian calls will have to change and a lot of others in other republics. The best CIS hams can hope for is to
have a moratorium on reissue of existing calls in another republic immediately after the changeover occurs, but
this remains unclear. Another proposal (as yet unofficial) from hams would be to keep suffixes intact to provide
some sort of link with the old call. The proposed new prefixes, wef 1 January 1993, are as follows:
Azerbaijan 4J
Moldova ER
Georgia 4L

The DXCC Desk had been accepting these stations for DXCC Credit despite the fact that they were operating under Yugoslavian authority and not Bosnia-Hercegovina licensing.

European Russia-Karelia16121994-04-13"Thanks to Ed Kritsky, NT2X for the following update on CIS calls:
The following information reflects the latest in a very confusing tale of the CIS callsigns, when it comes to Karelia: They currently use the following series:
UA1NVA-NZZ (UA1NA-NZ aren't Karelia, they are the old-timers in the city of St. Petersburg).
RK1NWA-NZZ Club stations. Please notice that only 3-letter suffixes, where the second letter of the suffix is either W, X, Y or Z, signify club calls.
RN1NA-NZ In Karelia they begun issuing individual calls in the RK-series, with 2-letter
My correspondent told me something quite interesting. IIt appears that about 2 weeks ago their radioclub was informed by the Ministry of Communications in Moscow (aka GIE) that special event stations in Karelia will be allowed the use of EM1N-call series. This may mean two things:
a. There exists a possibility of the EM-prefix use elsewhere in Russia.
b. EM-prefix was assigned to the Ukraine by the ITU; there is some sort of agreement for the use of that prefix by Russia - or Russia will be using this prefix without express permission from the Ukrame, i.e in error (!). Beats me.
There is also a small number of UN1-calls in existence in Karelia. They are not to be confused (try!) with the current assignment of the UN-series to Kazakhstan. The clue: Kazakhstan issues only UN2-0 calls, but not UN1's (for now)."
 CS-CUPortugal, Azores, Madeira16251994-07-13"Portuguese Telecom (ICP) has made substantial changes to the prefix system for Portuguese  amateur licences as follows:
1. Regular callsigns still have prefixes CT1 and CT4 for Portugal, CU for the Azores and CT3 for MadeIra.
2. Special event callsigns will be allocated as follows:
a) Portuguese mainland:

but are reserved for the National Repeater Service (VHF and UHF).
5. Callsigns with a single letter suffix are only issued to multi-operator stations
for contests and DXpeditions.
6. Single-operator stations may apply for special call signs, but the suffix must
be the same as the operators' regular call, eg CS6EEB for CT1EEB, etc.
7. Foreign amateurs applying for reciprocal licences will be issued with the
regular prefix/own call,
eg CT1/G0MQS, etc."

CS-CUPortugal, Madeira, Azores16291994-08-10"See DXNS 1625 and 1626. Luis, CT4NH has advised DXNS that the proposal to withdraw certain amateur prefixes was as a result of some "non-DX minded" Portuguese amateurs actually making such suggestions to their licensing authority. Thanks to the intervention of The Portuguese DX Group (GPDX) the authority has Rostponed the proposals for later discussion. There· can be no doubt that the loss of calls such os CQ7N, CT2A, CT3M, CR3M, etc, would be felt by participants in the major contests - especially WPX. DXers everywhere will wish GPDX well in thelr negotiations and trust the outcome IS favourable. "
