  • Only one signal/band is allowed at any time for one station.

Exchange:

  • RS or RST + serial number starting with 001 + QTH Locator (6 character).

Scoring:

  • Total aggregate score of all rounds
  • There will be four separate table of results:
    • YO single, YO multi, others single, others multi

Logs:

  • Only electronic logs in EDI format are accepted.
  • The log must contain the following information:
    • Date (TDate)
    • Callsign (PCall)
    • QTH locator (PWWLo)
    • Category (PSect) SINGLE or MULTI Band (PBand)

Logs needs to be uploaded to the address: upload page in 7 days from the round end. Received logs will be displayed on the dedicated web section. Logs received after the deadline will be used as check-logs.

Results:

Awards: 

Winners of 1st, 2nd and 3rd places for each section will receive paper and electronic awards.

Remarks:

All participants who sent logs will be listed in the results table. For QSO validation, additional check-logs will be used. These check-logs will be obtained, when possible, from the organizers of other contests taking place in the same time.

QSOs made with stations which haven’t sent logs, and their log was not obtained from organizers of other contests will be scored as follows:

  • zero points if the call is unique (can’t be found in any other logs)
  • if the worked call is present in other logs, the QSO is valid if:
    • the received serial number is correlated with the time of the QSO
    • the received QTH locator is the same as the one received by the majority

Example:

  • The call HA8XYZ appears in five received logs. If the serial number received from HA8XYZ is increasing with the time of the QSO on all available logs, the QSO with HA8XYZ will be valid
  • The call HA8XYZ appears in 10 received logs. In 8 logs received QTH is KN06LN, and in 2 logs received QTH is KN07LN. QTH KN06LN will be considered the correct one.

If the time difference is higher than 5 minutes, the QSO is scored 0 points.

The QSO will be scored 0 points for the participant who made this type of erorrs:

  • wrong serial number
  • wrong QTH locator

or incorrect callsign reception (with or without /p)

The preliminary results will be displayed in 15 days from the log sending deadline.

Final remarks:

  • Dupes are scored with zero points
  • Serial numbers out of sequence are not affecting score, if they are correct
  • Use of DX cluster is permitted, except self spots
  • Making skeds via www.on4kst.org is permitted and encouraged
  • log file name should be CALL_month_1926.edi (for example YO0XXX_4_1296.edi)
