RaDAR – Updated rules for the challenge for 2018

 

After careful consideration, the following minor changes have been forwarded for inclusion in the rules book for 2018.

RaDAR Challenge

1. Aim

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.

00:00 UTC to 23:59 UTC on Saturday 7 April 2018, Saturday 14 July 2018 and on Saturday 3 November 2018. 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 2018 the WARC bands will be excluded even though the RaDAR Challenge is not a “contest” as such.

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

5. Exchange

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).

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.

8. Moving RaDAR stations

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 (Changes for 2018) : 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. 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.

9. 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.

10. Log Sheets

Log sheets must be submitted by 14 April 2018, 28 July 2018 and 10 November 2018 and sent by e-mail to edleighton@gmail.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.

  1. Eddie, great to see. With the thousands of new SOTA summits in ZS too, this provides a great opportunity to combine award programs in a single activation.

    Cheers,

  2. This looks like a really interesting challenge, I’m looking forward to participating later in 2018. Has there been any discussion about adapting the distance rules for steep and mountainous terrain? For example, hikers might travel at least 1 Km OR change 100-300 m of elevation after making 5 contacts.

    Cheers,
    John VA7JBE
