Station description

WRTC-2010 is for the first time Field Day style competition.

All competitors will be located in the same geographical area within 40 x 30 km where height differences are not greater than 40 meters. All competitor locations will be separated at least 500 m from each other.

When you get to your location you will find ready to go (installed):
• 20/15/10 m tri-bander with one feed line and PL-259 male connector on 12 m tower with antenna rotator and control unit
• 40 m Inverted V dipole with feed line and PL-259 male connector
• 80 m Inverted V dipole with feed line and PL-259 male connector
• 2 x 100 watts peak power monitors
  Peak power monitors act on forward power only, which is greater than transmitted power when SWR > 1. In order to transmit 100 W to a mismatched antenna, an external tuner is needed to bring the SWR down, thus avoiding premature triggering of the power monitor.
• 2 PL259-PL259 jumpers for 100 watts peak power controllers
• Tent
• 2 kw Power Generator with 30 m power cable going to the tent
• 50 Liters of gazoline for generator
• 3 x 5 EU (Schuko) outlets
• 2 lamps
• Electrical Fan
• 3 plastic tables
• 3 plastic chairs
• WC cabin with hand wash facilities
• 30 liters of drinking water

Since this is a field day style operation each team will have a generator which has to be filled with gasoline. To avoid team members spending their time for re-filling generator we will have specially dedicated person at every location to help keeping it up and running during the contest period, so teams will concentrate on the contest battle.
