ON4WRC - West Vlaamse Radio Club member of the UBA Belgium Amateur Radio Association.




Each year members of our radio club are make the move to the island of “Schouwen Duiveland” in the Netherlands to participate in the annually IOTA contest.
Reason for this location choice is simple, this is the nearest location from our QTH, qualifying for this contest according to the RSGB IOTA contest rules. This move is like a real DX expedition, all needed Radio equipments, antennas, masts, computers for logging, WIFI links for the network, catering, camping equipment, powering equipment must travel with us.
The preparation and testing of the equipments is always starting long before the Big day. The antennas are always fine tuned and tested during the Fieldday, this is also a general repetition for the complete team in building up a complete Radio shack.
