The RaDAR “Challenge” is a unique event aimed at promoting the use of Rapidly Deployable Amateur Radio stations. Categories may be changed at any time during the challenge. The points system is so structured as to encourage portable RaDAR operations especially moveable RaDAR stations.
RaDAR operators are encouraged to be self sufficient during each challenge, not only with power supply and communications equipment but food, water, protective clothing and shelter, not forgetting the first aid kit.\
The challenge is on for 24 hours from 00:00-23:59 UTC but you have to pick a 4 hour period during this time to make your contacts.
Best description of the rules can be found in the SARL contest manual: http://www.sarl.org.za/Web3/Members/DoDocDownload.aspx?X=20161222085537waqSliCvbT.PDF
However, I found the description of the rules a little difficult to read. A short 10 point summary:
1. All legal modes can be used, all legal amateurradio bands can be used. Repeaters cannot be used.
2. Exchange: Callsign, Name, RS(T), QTH, Grid locator (6 digits, better 8 or 10 digits)
3. Scoring: 1 point every QSO. If the stations has moved you can make QSO again with a previous worked station.
4. Multipliers: 1x fixed RaDAR station (in building away from home), 2x field RaDAR station (camping), 3x Moving RaDAR station.
5. Bonus points: 5 points for one sat or digi QSO, 5 points for one RaDAR to RaDAR QSO on same continent, 10 points for one RaDAR to RaDAR intercontinental (DX) QSO.
6. After 5 QSOs you have to move, of course you are allowed to make more QSOs but they are not counting.
7. Distance to move see picture!
8. Use a log sheet for every different location see: http://radarops.co.za/wp-content/uploads/2015/07/11046905_10152762072212759_727315224761083499_n.jpg
9. A photo of the station should accompany every log entry including each new
location that moveable RaDAR stations visit.
10. Log sheets must be submitted by 15 April 2017, 29 July and 18 November 2017 and
sent by e-mail to edleighton@gmail.com
