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.

When:

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

Where: 

160m, 80m and 40m only

Modes:  

Any within your licence

Power:

Any within your licence

Eligibility:

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

The LF Challenge is an individual operator competition.  Where an operator has multiple call signs, contacts with all call signs may be combined, but only if all of the call signs are used for single operator operation.  Call signs used or linked with multi-operator contest entries or multi-operator Special Event Call signs are not eligible for awards.

Unattended and/or semi or full automation of any QSO is not permitted.

Scoring:

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:

All logs must be uploaded by 23:59 on 5th April following the Challenge period.

Awards:

Awards include Trophies, Salvers and certificates. Trophies will be awarded for each of two modes: (i) CW and Phone (non-MGM) and (ii) Machine Generated Modes (MGMs). ‘MGM’ uses the IARU Region 1 MGM definition. RTTY and wsjt-x modes are MGMs. Digital voice counts as phone.

Trophies:

The Penallt Trophy (travelling cup), given in memory of Allan Phillips, GW0BIC, will be awarded to the CDXC member with the highest number of DXCCs worked using only non-MGM modes..

The Tindle Cup (travelling cup) will be awarded to the CDXC member with the highest number of DXCCs worked using only MGM modes.

Salvers:

The two Trophy winners and the CDXC member with the highest number of DXCCs on 160m, 80m and 40m (irrespective of mode) will each receive an engraved salver to keep.

Certificates:

Certificates of merit will be awarded to CDXC members placed runner up and third on 160m, 80m and 40m (irrespective of mode).

Certificates will be e-mailed to winners prior to the following AGM date.

Notes:

Each Trophy may be won by an operator only once in any three-year period.

Trophies and salvers will be presented at CDXC events throughout the year. Travelling cups will need to be returned at the winner's expense after about nine months. Trophies will only be posted to members who agree to meet the full postage costs.

CDXC especially acknowledges the contributions of Michael G7VJR in conceiving Club Log and providing it for use as a tool for this Challenge.
