RaDAR Contest – Summer 2012

1. Aim

An event aimed at promoting the use of Rapid Deployable Amateur Radio
(RaDAR) stations and antennas, preferably without relying on normal
mains power (Eskom). This contest is for everyone, at home, mobile or in
the field. Any mode can be used CW, SSB, AM, FM or any digital mode.
Any amateur band or Satellite can be used. The points system is so structured
as to encourage portable operation. Score multipliers are used to
reward and favour the Portable / RaDAR stations using temporary antennas
and alternative power supply sources.

A mobile station will be treated as a field station
A portable station not meeting the requirements as a field station will be
treated as a home station.

9. Bonus points for Portable and RaDAR stations

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. What constitutes a true RaDAR Station

To be considered as a true RaDAR station, the entire station equipment,
radios, batteries, mast, antennas and refreshments must be easily portable
and hence the need to carry the equipment for at least 1 km prior
to setting up.
For the sake of safety, it will be acceptable to carry / backpack your entire
station for a distance of at least 1 km and end up where you started
from – your home, campsite, picnic site, motor vehicle or wherever you
choose to operate from.
