    RaDAR Sport - ZS3DR Test case

    Posted: 15 Feb 2022 11:31 PM PST https://zs6bne.wordpress.com/2022/02/16/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

    Page 1

    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 QSOs 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

    Tjaarts 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.

    ZS3DRs 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 QSOs
    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!
