CDXC LF Challenge Rules

In the LF Challenge, the objective is to work as many DXCC’s as you can on 160M, 80M and/or 40M in the month of March.

All logs must be uploaded to Club Log; no paper or e-mailed logs will be accepted.  In keeping with recent rules changes in large contests, uploads need to be completed and the competition will be closed five days after the end of the Challenge period.

Good luck everyone!


00:01 GMT 1st March  to 23:59 GMT 31st March


160m, 80m and 40m only


Any within your license.  FT8 QSO count as Data QSOs.


Any within your license


The LF Challenge is open to any licensed amateur world-wide, but only fully paid up members of CDXC are eligible to receive Awards.


Each DXCC entity worked is counted once only, regardless of how many bands or how many modes that entity is worked on.  The object is to work as many DXCC entities as possible.  In the event of a tie based on DXCC entities, the higher score by Band-Slots will win.

Log entry:

Via upload to Club Log and electing to enter the LF Challenge on the Club Log website. Regular uploading of your log during the month is encouraged – registration and at least one upload must be made by 15 March and once per week is preferred - as this helps to drive the Challenge and provides a spectator sport for all to see.  (If you are not QRV until after 15 March but would still like to take part, please send an email to the Awards Manager.)

E-mailed or paper logs will NOT be accepted.

Log Verification:

No QSLs are required, but in the event of a question the CDXC committee may request verification via other means.  By entering, participants agree that their Club Log entries may be viewed and queried by adjudicators and that decisions made by the adjudicators will be final.

Closing date:

In keeping with current large contest practice, all logs must be uploaded by 23:59 on 5th April following the Challenge period.








The Penallt Trophy, given in memory of Allan Phillips, GW0BIC, will be awarded to the CDXC member with the highest number of DXCC’s worked.  The Tindle Cup will be awarded to the runner-up. Trophies will be awarded at the CDXC AGM/Summer Social in July 2013 and will be held for 9 months.

The top three placed entrants and the entrants with the highest score on each of the 3 bands will receive engraved salvers to keep. Salvers will be posted shortly after the AGM.

Certificates of merit will be awarded to the entrants placed overall 4th to 10th. Certificates will be e-mailed to winners two to threee months after the closing date.
