Rules of the UBA International Prefix Hunt

UBA International Prefixhunt 2016

This is not a contest in usual sense but a competition, which runs over the whole year and enables you to measure your achievements in prefix chasing. Even if you are not a contester you can easily participate because every QSO you make on every HF band counts for the competition.
Changes are in red!

1. Dates

From January 1, 2016 00:00 UTC until December 31, 2016 23:59 UTC.

2. Bands

All HF bands (160, 80, 40, 30, 20, 17, 15, 12 and 10m).

3. Categories and modes

Single Operator only (SWL's are also allowed to participate).
  • Mixed Mode
  • Phone (SSB, AM, FM)
  • CW
  • Digital Modes (RTTY, PSK, etc...)
Everybody will be in Mixed Mode. Once you made a QSO in the other modes the program will automatic calculate the score for the other categories.
Multi Operator & Clubstations
  • Mixed Mode only
For stations who are also operating in Mo categories in contests and for Clubstations.

4. Points, Multipliers and Final score

  • Every different prefix counts 1 point on each band.
  • Every different prefix counts once as a multiplier.
  • The sum off all prefixes on all bands multiplied by the number of different prefixes.

5. Logs

Only electronic logs via email in ADIF format will be accepted.
Send your log of the past month before the 5th of the following month to the Competition Manager in order to compile an interim results list.
Just export your log of the last month in ADIF. You don’t have to calculate your score yourself.
Last logs must reach the Competition Manager before the 10th of January of the following year.
Name your file “yourcall-month in figures.adi” (ex: ON7SS-01.ADI for the January log). There is no need to mention a claimed score.
All logs will be treated in the strictest confidence and will not be made public.

Mail your log to ubaprefixhunt [at] uba [dot] be (ubaprefixhunt{at}uba{dot}be)

6. Certificates

Digital competition certificates will be granted to all participants who reach at least 300 different prefixes.

7. Remarks

  • We do count on your hamspirit and expect you to log only QSO’s which took actually place.
  • You may enter the competition during the year, in which case your QSO's start counting from the month before you have send your first log. (ex log send in April, QSO's start counting form march 1)
  • If you have more then one callsign (ex ON7SS and OO9O) you may merge both logs.  If you are allowed to use a special prefix during the year (ex OP instead ON in november) you may also merge this log. The same applies when changing callsign.  This however is only allowed if it are personal callsigns, so no clubcalls.  The certificat and the call used in the results will mention the first used callsign.  Additional calls will be mentioned in a separate column.  If you are active during the year in a different DXCC you can not merge that log.  However you can send in a participation from that country (ex LX/OO9O).
  • If your callsign is used during a contest in a Multi Operator category you may not use these QSO's for the competition. Then you have to enter the Multi Operator & Clubstations category.

Good luck in Prefixhunting
