RSGB DX News Sheet #1387, dated 1989-10-18, reports:
However, the change appears to have taken place in October, 1988, not October, 1989. See for example, the QSL of LY2WW for a QSO on 1988-10-29.
"The three Baltic states of Estonia, Latvia and Lithuania were independent states before WWII, but were incorporated into the USSR during the war. As independent states, they were allocated special amateur prefixes UR, UQ and UP. At the beginning of October, the Amateur Radio Society of Lithuania received approval from the authorities in Moscow to replace the UP prefix with LY. Over 100 Lithuanian stations are now using the LY prefix, and the number is increasing daily."

RSGB DX News Sheet #1398, dated 1990-01-10, reports:
"Amateurs in Estonia are soon expected to start using callsigns in the series ES1-ES0. The country will be divided into 10 call areas similar to those which existed before WWII."
"The new ES callsigns have appeared from Estonia. The prefix number indicates the province as follows (tnx LNDX):
ES1 Tallin and northern islandsES2 Harju RajonES3 Haapsalu, Rapla and PaideES4 Kohtla-Jarve, Sillamae, Rakvere and NarvaES5 Tartu, Jogeva and Polca
ES6 Valga and VoruES7 ViljandiES8 ParnuES9 special events."
Based on the above, and feedback from Club Log users, Club Log maps the ES, YL and LY prefixes for these entities as follows:
|Old prefix||New prefix||DXCC entity||Start date of new prefix used by Club Log|
|UR||ES||Estonia||1989-12-31 (=1990-01-01 local time)|
NoteUR2RMC became ES5MC
UP1BZZ became LY2ZZ
