RaDAR November 2013 Contest Announcement and Rules


1. Aim

The RaDAR-America contest is an event aimed at promoting the use of Rapidly Deployable Amateur Radio stations throughout North and South America. This contest is for all licensed radio amateurs. A choice is made prior to the contest to participate in one of the defined categories. The points system is so structured as to encourage portable operation, especially moveable stations.
The rule structure is very close to that formulated by the founder of the contest idea: Eddie ZS6BNE
This contest will take place at the same time in South Africa (the Nation from which the idea originated), as it will here in the Americas. Please note that the most significant difference between the South African RaDAR rules and the RaDAR-America rules are in the suggested frequencies, which have been adapted and changed to comply with the IARU Region 2 band plans. If you choose to operate on the suggested South African RaDAR frequencies, please note that some are in the EXTRA band section for US operators and others are entirely outside of the IARU 2 band plan.

2. Date and Time

First Saturday of April and first Saturday of November starting at 14:00 UTC and ending at 18:00 UTC (4 hours).

3. Bands and Modes

All amateur bands, besides the WARC bands, are allowed including cross band contacts via amateur radio satellites.

All Amateur Radio operating rules within the country of operation are to be respected and followed at all times.

QSOs via terrestrial repeaters will NOT be allowed. You must make all of your contacts on Simplex only.

Modes – CW, SSB, AM, FM or any digital mode.

4. Suggested HF and VHF voice calling frequencies

The frequencies posted by HFPack http://hfpack.com/air/
are suggested as HF activity frequencies if not already in use. Please note that HFPack operates USB on all bands to achieve complete compatibility with a wide variety of commercial and Military portable HF radio systems that amateurs are using.

Suggested VHF frequency: 144.300. Frequencies that have a potential conflict with repeater inputs (low end of 146 Simplex) are to be avoided.

Contesters are requested to operate by The Amateur's Code
and with the request to keep in mind that HFpack has established methods for courteous operation on the suggested frequencies
[Please note that HFPack does not sanction contests and that this contest is not organised by a Founder or Moderator of the group.]

Contesters are also requested to respect all International Distress frequencies:
as well as 146.520 MHz - the National Simplex Calling Frequency. Fixed stations are however encouraged to monitor these frequencies, so that they may be able to assist HAMs in distress. 

Contacts made within +/- 5kHz of the IARU Region 2 HF Distress Frequencies will not be counted for a valid QSO.

Please additionally respect the NCDXF/IARU beacons operating on 14.100, 18.110, 21.150, 24.930 and 28.200 MHz.

5. Recommended digital modes frequencies

CW: HFPack frequencies.
Other: all legal digital frequencies at established activity centers for the respective mode.

6. Exchange

Call sign, Name, Report (RST), QTH and USNG grid locator (at least 6 digits). Note the grid locator can change as RaDAR operators are allowed to move to the next destination at any time.

Maidenhead grid LOC information may be submitted instead of USNG locator. The grid locator of 6 digits is acceptable but should preferably be accurate to 10 digits.

If the grid locator is not known, then some other information that could describe the location, e.g. Mabula Lodge, 40 km west of Warmbaths. Note that several SmartPhone HAM log apps support this feature (e.g. HamLog for the iPhone).

7. Scoring

1 point per QSO.
1 QSO per mode, per band / satellite, per call sign. You may work another call sign several times, but only once per mode and only once per band throughout the entire contest period (you may work several call signs per band and per mode).

8. Categories and multipliers

The following multipliers are applicable to determine the final score.

Category multiplier:

x 1 – RaDAR Fixed station (At home or in another building). These stations may NOT call QSO, allowed to monitor and reply to QSOs only.

x 2 – RaDAR Field station (Portable away from home). These stations are to log themselves as /p ("portable"). At least one photo or video of the station MUST accompany the log.

x 3 – Moving RaDAR station, Car / Motorcycle / Bicycle / Maritime – Minimum 3 miles (approx. 5 km) per 5 QSOs. These stations are to log themselves as /m ("mobile"). A photo or video of the station MUST accompany every log entry.

x 4 – Moving RaDAR station, on foot – Minimum 0.6 miles (approx. 1 km) per 5 QSOs. These stations are to log themselves as /pm ("pedestrian mobile"). A photo or video of the station MUST accompany every log entry.


1) Moving RaDAR stations can move at any time but are required to move to the next destination after five contacts have been made. The move needs to cover the required distance before further contacts are allowed to be made.
2) Moving stations may also operate while in motion, but need to have covered the required distance for every 5 QSOs. Note: safety and all (traffic) laws take precedence at all times.

Power multiplier:

The power multiplier that applies is determined by the highest power output of any of the transmitters used during the contest.

5 watts or less the power multiplier is 6.
6 to 50 Watts, the power multiplier is 4.
51 watts or greater, the power multiplier is 2.

9. Bonus points (All categories)

5 Points (Equivalent to five QSOs) for a minimum of one satellite or any digital mode QSO involving a computer. (For clarity: Thereafter 1 point per Satellite / Digital modes QSO)

10. Notes: 

1) A photo or video of a "Field" or "Moving" station MUST accompany every log entry.
2) Images or videos may be posted on the contesters preferred website, preferred website service or else; links must however be listed within the log file. Photos may alternatively be copy/ pasted in to the log.
3) All logs and submitted photos will be published at http://RaDAR-America.blogspot.com under the following copyright:
