In this context, 'portable' refers to any callsign that includes a '/' character. The term 'suffix' in this context refers to a sequence of characters commencing with, or terminated by, the '/' character.
The following are ignored in the mapping process, i.e. a callsign is mapped with these characters removed:
/LH, /PM, /QRP, /QRPP, /EO, /GA, /GP, /XA, /XB, /XP, /AE, /LT, /AG, /AE, /2K, /FF, /Y2K, /SK, /SJ, /QRO, /QRQ, /QRS, /HQ, /RP, /P, /M/P, /P/M, /N, /A/M, /QRP1W, /QRP5W, /LGT.
Suffixes of "/" plus three or more alpha characters are also removed.
Thus G3PMR/LH, G3PMR/2K, G3PMR/QRP, G3PMR/JAMBOREE are all mapped as if the callsign was G3PMR.
Stations with a purely numeric suffix are mapped as callsigns with the prefix digit replaced by the suffix digit(s).
Thus W3ABC/6 would be mapped as if the callsign was W6ABC.
UA9XYZ/3 would be mapped as if the callsign was UA3XYZ, RA4ABC/8 would be mapped as RA8ABC, with the exception that the zone would be mapped to zone 18, by the rule immediately below.
Russian stations operating from Asiatic Russia, outside their own Federal District - zone mapping
Stations signing /8 (Ural Federal District) are mapped to zone 17, which is the default zone for Asiatic Russia.
Stations signing /9 (Siberian Federal District) are mapped to zone 18 by a software rule. Zone exceptions are used for the case when the station is in zone 17 or 23.
Stations signing /0 (Far Eastern Federal District) are mapped to zone 19, which is the default zone for prefixes from regions R0. Zone exceptions are used for the case when the station is in zone 18.
Callsigns which have an exception and have a suffix that is an entity prefix
If 5B4AHJ/JD1 has an exception for a given entity then JD1/5B4AHJ would also be mapped to that entity.
This halves the number of exceptions needed for this type of callsign.
Suffixes /MM & MM/.
/MM is mapped to Maritime Mobile.
MM/ is mapped to Scotland.
Thus 5B4AHJ/MM is mapped to Maritime Mobile, whereas MM/5B4AHJ is mapped to Scotland.
French Overseas Territories with single-letter suffix
Callsigns with prefixes FO, FR and a single character suffix are mapped as follows:
FO/A - Austral Islands
FO/C - Clipperton Island
FO/M - Marquesas Islands
FR/E, FR/J - Juan de Nova, Europa
FR/G - Glorioso
FR/T - Tromelin
3D2 calls with single-letter suffix /C & /R
Callsigns with prefix 3D2 and a single character suffix /C or /R are mapped as follows:
3D2/C - Conway Reef
3D2/R - Rotuma
JD/M & JD/O suffices
Callsigns with the suffix /JD/M or /JD/O are mapped as follows:
/JD/M - Minami Torishima
/JD/O - Ogasawara
KC4/ & /KC4 suffices
Any callsign with the suffix KC4/ or /KC4 is mapped to Antarctica.
HK0 calls with suffices /A, /HK0/A, /M, /HK0/M
HK0 callsigns with the above suffices are mapped as follows:
/A, /HK0/A - San Andres
/M, /HK0/M - Malpelo
ZK1 & E5 callsigs with suffices /N & /S
ZK1 & E5 callsigns with the above suffices are mapped as follows:
/N - North Cook Islands
/S South Cook Islands
Callsigns with a prefix BS and a terminating suffix /7 are mapped to China.
This rule is necessary to avoid mapping to Scarborough Reef.
Callsigns with a prefix TK and a terminating suffix of 2A or 2B are mapped to Corsica.
2A & 2B are the French Department numbers for Corsica (Corse du Sud, Haute Corse) and are often appended to callsigns for French contests.
Mainland France department numbers are numeric and are mapped by a different rule..
IS/, IM/, /IS, /IM
IM0 and IS0 are prefixes for Sardinia.
Some stations operating portable with their home call sometimes drop the zero in these prefixes, e.g. I2AXCS/IS, IM/IV3NVN.
Callsigns with these suffices are mapped to Sardinia. Without this rule they would map to Italy.
