All files must be in standard ASCII format (i.e. no tabs or other control characters).
The log file must consist of one logical line of data per QSO. Each contact line must be terminated with a carriage return character.
The QSO data defined below must appear in each line, except that a hyphen in any field, or a field which is all blanks (spaces) will be taken as indicating a data item which is the same as in the previous contact.
Each field except the last must be padded out to the correct length with blank characters and neighbouring fields must be separated by a blank character.
Exact adherence to the start and finish columns given below is not mandatory but all data must be column-aligned within the specified field limits, e.g.: every callsign must start in the same character column and all must fit between character columns 22 and 36.
1 - 6 Date in YYMMDD format
8 - 11 Time in HHMM format
13 - 16 Band in MHz (embedded periods are allowed, e.g. 1.8)
18 - 20 Mode (A1A, J3E, F3E etc)
22 - 36 Callsign (left aligned)
38 - 40 RS(T) sent
42 - 45 Serial number / Power / Zone / State sent
47 - 49 RS(T) received
51 - 54 Serial number / Power / Zone / State received
56 - 59 New Bonus / Multiplier (country prefix / county code etc)
61 - 64 Points (Note: for VHF contests only, character 60 may be
used if the points exceed 9999)
66 - 71 Station callsign / Operator callsign for multi-op events
73 - 128 Further contest specific data, e.g. postcode, district
code or QTH locator received.
THIS FIELD MUST BE TERMINATED BY <CR>.
Zero point QSOs such as duplicates, unfinished contacts etc
may be explained here. This field should be left justified
and may contain spaces but not tabs.
Logs must be submitted as a single contiguous file (in chronological order of contact) for each station. Separate files for each band are NOT required.
The log data filename must consist of the call sign and the extension .LOG, e.g.: G9XXX.LOG.
Entries in contests where more than one callsign is used, e.g. VHF Field Day or AFS, should contain all the entrys logs as separate files.
In contests where the same station submits multiple logs on the same band, such as LF Cumulatives, the filename should be suffixed with a distinguishing numeral e.g. G9XXX1.LOG, G9XXX2.LOG.
Standard abbreviations must be used, e.g. RSGB two-letter district codes, ITU Country prefixes, US Postal Service two-letter State abbreviations, ARRL sections, etc.
