This program routine enables contest log processing, transparency of results, facilitates the work of contest organizers and uploading contest logs in EDI format. The CC Routine cross-compares data from all logs in the database to detect possible malfunctions. For the most accurate results of checking the contest logs, it is necessary to collect as many logs as possible.
During IARU (Region I) VHF Commitee meeting held in Vienna (Austria) in February 2007, admission of contest logs will be possible exclusively in digital REG1TEST (EDI) form, as it was agreed there. Most of national amateur societies will follow that recommendation starting with January 1st 2008. This is our contribution to needs of unique and easy processing high quantity of contest logs.
First idea about creating this kind of application came from Krešo 9A2HM in December 2006, which was later supported by Željko 9A4FW. During VHF contest "Vidovo 2007" first testing were carried out. Since then, I have significantly improved the program.
Web application enables contest log uploading in EDI form. After that, application will show uploaded log again and display possible data error warnings and allow checking and/or correcting data.
After loading the log into the database, You can run a for-deadline cross check routine for your (or any other) callsign and see the error log that the CC program printed for that call sign (as well as for another call sign). Before the deadline cross check check routine, it only calculates the sum of the QRB and the double connection. After the deadline for submitting the log, the administrator starts the cross check routine.
That's possible because the complete application was written in php programme language and is running on-line (on Webserver) in real time and without presence of administrator.
QRB will be recalculated for all QSO's, to insure unique calculating for all stations, using this formula:
Recommended by the IARU Region 1 VHF Committee
(Noordwijkerhout, 1987), i.e. the formula proposed by PZK,
for calculating distances in VHF and Above Contests and
the "commenced km" points rounding method (Lillehammer, 1999).
Distance = 111,2 * arccos(sin Latitude1 * sin Latitude2 + cos Latitude1 * cos Latitude2 * cos(Longitude1-Longitude2))
where the conversion factor is 111,2 km/deg.
| Points rounding methods (zaokruživanje) |
| Distance | Commenced km | Math | Truncation |
| 0 km | 1 | 0 | 0 |
| 43,2 km | 44 | 43 | 43 |
| 56,7 km | 57 | 57 | 56 |
Contest administrator's (contest manager) intervention for singular QSO in log (recognition or rejection) is possible and it is a normal feature. Two types of administrator accounts are enabled: main administrator accounts (e.g. regional or national manager), with access to all contests (data), and singular contest administrator account (e.g. national or local contest manager), with licence depending access.
All admin interventions and errors found by CC routine, upload date and time and cross check date and time can be seen in contest error logs or in placement view. That way, everybody can monitor contest development and results and even complain on displayed errors, data or results.
Development and improvement of CC Routine, like any other software product, is a never-ending process. We are open for any suggestions and ideas.
