These are research notes for the 4L prefix in the period 1990-94, which have been compiled in order to establish an appropriate date for the start of mapping the 4L prefix to Georgia.

August 1994 to date

The 4L prefix was allocated exclusively to Georgia from 1994-08-01.   From OPDX #319, dated 1997-08-24: Mamuka Kordzakhia, The President of the National Association Radio Amateurs of Georgia (NARG) reports to OPDX that <snip> "The Georgian Republic prefix of 4L has been in effect since August 1, 1994."

DXNS #1762, dated 1997-04-01, reports:

4L GEORGIA: Mamuka, 4L2M, President of The National Association Radio Amateurs

of Georgia (NARG), reports the following stations are pirates: 4L2DX, 4L3Q, 4L44N,

4L50K, 4L55K, 4L611MC and 4L7F. Licensed stations using 4L prefixes (4L1, 4L4,

4L6, 4L7 and 4L0) have only two letters in their suffix, while Extra Class and club

stations have one letter in the suffix with one number (eg. 4L4L, 4L5O, 4L0B).

USSR special event and Georgian personal calls 1990-94 using suffixes starting F, O, Q, V

Before the 4L prefix was allocated exclusively to Georgia in 1994, the 4L prefix was used as a special event prefix for USSR stations. and also for some personal calls from Georgia. The prefix could be used for SES calls by any USSR republic, including Georgia. 

From 1970, until July, 1994, the normal prefixes for Georgia were RF6 & UF6, with the first letter of the suffix signifying the oblast. (Before 1970, the prefix was still UF6, but there was no system to indicate the oblast) Thus, personal calls were of the form UF6F, UF6O, UF6Q, UF6V followed by zero, one or two additional characters, where:

UF6F =  Georgia, oblast 012

UF6O = South Osetian, oblast 015

UF6Q = Adzhar, oblast 014

UF6V = Abkhasia, oblast 013

Thus, one may have expected the Georgian 4L special event calls to use the prefixes 4L6[FOQV]. This turns out not to have been the case. However, the digits other than 6 were  used, so the prefixes could potentially be 4L[0-9][FOQV]. However, this could lead to conflicts, for example, in theory, 4L1F could have been used from Leningrad oblast (UA1F), 4L0F from Sakhalin (UA0F), etc. In fact 4L1FS was used from Leningrad in 1989.

The following 4L[0-9][FOQV] prefixes are known to have been used from Georgia before 1994-08-01. This data is largely based on the QSOs in the Club Log QSO database, with the QTH being manually verified via various internet resources. This is almost certainly not a complete list, as it is based only on QSOs that have been uploaded to Club Log. Several thousand QSOs have been reviewed in order to compile this data. Callsigns with just a single QSO in the period of interest have been ignored. Callsigns of the form 4L[0-9]F[A-Z] are personal calls.

4L calls October, 1990 to July, 1994 not QRV from Georgia

The following calls were QRV in the period of interest, but not from Georgia.

These require callsign exceptions, or, in the case of the 4L3 stations, an additional prefix mapping..

4L0DXC, Ukraine, 1991, 1992

4L19A, European Russia, 1992

4L1NV, European Russia, 1991

4L1QRQ,  European Russia, 1990-94, 4L1QRQ/3 (1994)

4L20A, 4L21A, 4L22A, 4L23A, 4L24A, European Russia, 1992

4L3D, 4L3Q, these are thought to be European Russia, but confirmation required, 1992-93

4L3FRM, European Russia, May, 1992

4L4F, European Russia, 1990-1993

4L4IR, European Russia, 1992

4L4UPA, European Russian, 1992

4L6HMC, 4L6HMC/A, European Russia, 1992

4L1QRQ/9 (1990), 4L9H, Asiatic Russia, 1992


a) Although the 4L prefix was not assigned exclusively to Georgia until 1994-08-01, many Georgian stations using the 4L prefix were QRV from October, 1990 to July, 1994.

b) There were a few non-Georgian stations using the 4L prefix that were QRV in the same period, but these were far out-numbered by the Georgian stations.

c) Therefore, Club Log maps the 4L prefix to Georgia from 1990-10-01. Callsign exceptions are used to map 4L calls from other entities in the period 1990-10-01 to 1994-07-31, except for 4L3 stations, which are mapped by the 4L3 prefix.
