RaDAR Sport – ZS3DR Test case

In the year 2021 RaDAR Sport was introduced and practical experiments done during the last of three challenges on November the sixth. Much development and updates were done to accommodate the situations which may arise during a RaDAR Challenge.

New fields were introduced into the online logger to cater for these situations and here presented as a test case and to explain how the online community logger and evaluator are used to evaluate any of the RaDAR Challenges.

Please refer to the RaDAR rules at http://radarops.co.za/index.php/radar-rules/

The new columns introduced are Power and x / 5, where Category existed on the day of the challenge already. Here ZS3DR took part as a category B (SINGLE PERIOD, FOUR HOUR ops) RaDAR station, moving by vehicle (Vehicles, motorcycles and motorboats (motorized transport) – move 6 km every five contacts).

If more contacts were made than the required five per deployment, the best five QSO’s can be selected for evaluation. The best options are where a valid grid check took place (Bonus points) and second at least where QSO information has been validated by other operator log submissions. Good choices could be those where the operator is also taking part in the RaDAR challenges.

So in effect, after the RaDAR challenge has taken place the operator can come back to the online log and make these decisions and also correcting any mistakes that may have crept in during the logging process. Certainly after an ADIF upload this will be required as ADIF files only carry the most basic information. Once the logs have been submitted and refined by all participants then an evaluation can be done online.

Here again a test case for ZS3DR. Tjaart only operated two hours but category B runs for four hours unlike the RaDAR Sprint category C which is two hours but no motorised vehicles allowed.

Date, time and category selection

Tjaart’s operating times and category were selected for the test case evaluation for the 6th of November 2021. Fortunately all the guys that logged their RaDAR Challenge logs have provided valuable data to refine the system for this year 2022 and years to come.

On clicking the submit button, all the magic happens, within seconds. Concentrate here just on the results for ZS3DR.

ZS3DR’s Final result

Here we can see from the selections Tjaart made (Edited by ZS6BNE) to his logs that he made 10 official RaDAR contacts (Even though he had more QSO’s than the required five per deployment). His mode of transport / movement was a vehicle and moving stations have a multiplier of 3. That gives a score of 30. From the logs he had selected 2 were validated by other RaDAR operator logs right up to the grid exchange which gave him in total 4 bonus points. A subtotal was then calculated to be 34. The number of deployments (Five contacts per deployment) then come into play as a multiplier. Those stations that do multiple deployments within the time frame enjoy a higher score than other stations doing fewer deployments.

Each participants score presented graphically.

Once all the other call signs are correctly marked and refined by each participant (Here I will use that data to edit and test) then the graph will be quite representative of all the results.

Ensure you have your assigned PIN which is related to your call sign. The first RaDAR Challenge for 2022 is just around the corner, in April!
