The RaDAR contest is a unique event aimed at promoting the use of Rapidly Deployable Amateur Radio stations. This contest is for all licensed radio amateurs not limited to South Africa. A choice is made prior to the contest to participate in one of the defined categories but may be changed at any time during the contest. The points system is so structured as to encourage portable operations especially moveable RaDAR stations.
2. Date and Time
First Saturday of April and first Saturday of November (5 April 2014 and 1 November 2014), starting at 14:00 UTC and ending at 18:00 UTC (16:00 to 20:00 CAT) – Approximately two hours during the day and two hours at night within the South African time zone.
3. Bands and Modes
All amateur bands, besides the WARC bands, are allowed including cross band contacts via amateur radio satellites. Modes – CW, SSB, AM, FM or any digital mode. QSOs via terrestrial repeaters will NOT be allowed.
4. Suggested HF Calling frequencies
http://zs6bne.wordpress.com/2013/03/06/radar-calling-frequencies/ for the latest international list of frequencies.
Recommended digital modes frequencies – Refer to the SARL Contest Manual, General Rule 15.
The RaDAR contest requires more than a minimalistic information exchange. Accurate information exchange is considered more important than a large QSO count.
Call sign, Name, RS(T) Report, QTH and grid locator. Note the grid locator can change as RaDAR operators are allowed to move position at any time. The grid locator of six characters is acceptable but should preferably be accurate to 10 characters for higher position accuracy.
1 point per QSO.
Individual QSOs – per mode, per band, per satellite, per call sign.
7. Categories and multipliers.
The following multipliers are applicable to determine the
final score. If category changes were made during the contest than calculate accordingly.
x 1 – RaDAR Fixed station (At home or in another building)
x 2 – RaDAR Field station (Portable – away from home)
x 3 – Moving RaDAR station – Car / motorcycle / bicycle / etc., minimum 3 km
x 4 – Moving RaDAR station – On foot – minimum 1 km
Refinements will be done in 2015. The proposal will be that all moving stations will have a multiplier of 3 the only difference is the distance required to move.
Vehicles, motorcycles and motorboats etc. (Motorized transport) – 5km
Bicycles – 2km
On foot and paddle canoes – 1km
Wheelchairs – 500m
Note: Moving RaDAR stations can move at any time but are required to move to the next destination after five contacts have been made from the present location. The move needs to cover the required distance before further contacts are allowed to be made. This requirement tests the ability to rapidly re-deploy your amateur radio field station.
Power multiplier: The power multiplier that applies is determined by the highest power output of any of the transmitters used during the contest at any point in time.
x 6 – 5 Watts or less
x 4 – 6 to 50 Watts
x 2 – 51 watts or greater
9. Bonus points (All categories).
5 Points (The equivalent of five QSO’s) for a minimum of one satellite or any digital modes QSO involving a computer, smartphone or digital modes device. (For clarity thereafter 1 point per Satellite / Digital modes QSO)
5 Points for the first inter continental DX QSO – 10 Points if that QSO is between two participating RaDAR stations.
10. Log Sheets
The SARL RaDAR Contest manager – Eddie, ZS6BNE. Send email entries to edleighton (at) gmail.com. The closing date for logs is 19 April 2014 and 15 November 2014.
See https://www.dropbox.com/s/trkir582qf0fmh3/ZS6BNE-RaDAR-GenericContestLog2014.pdf for a log sheet specifically designed for the RaDAR contest.
Note: A photo of the station (JPG format) MUST accompany every log entry. A photo is required for each new location that moveable stations move to. These photos are used to promote amateur radio and the RaDAR concept showing where amateur radio can be used to communicate from and in the many different ways.
