RaDAR Challenge – 2019 and beyond
The RaDAR “Challenge” is a unique event aimed at promoting the use of Rapidly Deployable Amateur Radio stations. Categories (Fixed / Field / Moving) 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, with not only power supply and communications equipment but food, water, protective clothing and shelter.
2. Date and Time
RaDAR operators define their own operating time schedule. It’s up to each individual to plan his / her MAXIMUM, SINGLE PERIOD, FOUR HOUR ops. He / she should consider propagation with the ultimate goal of inter-continental RaDAR to RaDAR communications in mind. Share your plans with others to try and coordinate times.
00:00 UTC to 23:59 UTC on Saturday 6 April 2019, Saturday 13 July 2019 and on Saturday 2 November 2019. Twenty four hours will give equal opportunity to the international community of RaDAR operators.
3. Bands and Modes
All amateur bands are allowed including cross band contacts via amateur radio satellites. Modes – CW, SSB, FM or any legal amateur radio digital mode. As from 2019 the WARC bands will be INCLUDED. The RaDAR Challenge is not a “contest” as such, it’s an individual challenge.
QSOs via terrestrial FM repeaters should preferably not be used for the purpose of the challenge.
4. Suggested HF calling frequencies
See https://zs6bne.wordpress.com/2013/03/06/radar-calling-frequencies/ for the RaDAR Calling channels, the latest suggested international list of calling frequencies
The RaDAR challenge 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 and grid locator. The grid locator of six characters is acceptable but should preferably be accurate to 8 or 10 characters for higher position accuracy (especially for moving RaDAR stations). Various smartphone apps are used for this or pre-planning using maps is an alternative.
6. Scoring (For determining your own success rate)
1 point per QSO. Individual QSOs could be per mode, per band, per satellite, per grid location. If the moving RaDAR station has moved the required distance contact can be made with a previously worked station, again. Suggestions have been made to call CQ including grid location, for example CQ RaDAR from grid KG34acXXyy, to help callers determine whether it is possible for a new contact with a previously worked moving RaDAR station.
7. Categories and multipliers
The following multipliers are applicable to determine the final score. If category / mode of transport changes were made during the challenge, than calculate accordingly.
X 1 – RaDAR Fixed station (in a building away from home)
X 2 – RaDAR Field station (camping)
X 3 – Moving RaDAR station – see modes of transport below.
Modes of transport and required movement distances (moving RaDAR stations only)
Vehicles, motorcycles and motorboats (motorised transport) – 6 km
Bicycles – 2 km
On foot and paddle canoes – 1 km
Wheelchairs – 500 m
Aeronautical mobile stations are considered moving stations and can communicate at any convenient time.
Note : Moving RaDAR stations need to make five QSO’s before moving to the next deployment point, thereafter they are required to move to their next destination. The move needs to cover the required distance before further contacts can be made. This requirement tests the ability to rapidly and successfully re-deploy your amateur radio station. In the case of satellite communications, plans need to be made carefully to ensure you are at your new position before the satellite comes over the horison. This adds to the fun of RaDAR.
If it be gentlemanly to make further QSOs before moving then please feel free to do so but the QSOs in excess of five per deployment point can not be counted for points. Your extra QSO’s may well help others to achieve their QSO count. Help your fellow ham to achieve his / her goals if the opportunity presents itself.
8. Bonus points (All categories)
Five (5) points for a minimum of one satellite OR digital modes QSO involving a computer, smart phone or digital modes device. (For clarity thereafter 1 point per Satellite / Digital modes QSO).
Five (5) points for the first successful same continent RaDAR to RaDAR QSO.
Five (5) points for the first intercontinental (DX) QSO
Ten (10) points for the first successful inter-continental (DX) RaDAR to RaDAR QSO.
9. Log Sheets
Log sheets must be submitted by 13 April 2019, 20 July 2019 and 16 November 2019 and sent by e-mail to email@example.com Note: A photo of the station should accompany every log entry including each new location that moveable RaDAR stations visit. The results and photos are used to promote RaDAR and amateur radio.
