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:

European Russia-Karelia 1612  1994-04-13  "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)."

5. Callsigns with a single letter suffix are only issued to multi-operator stations

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.
