Some of the greatest achievements in my Ham career: Having build up a temporary station (Field Day-style ) to be installed for 24h operations, with the cooperation of a group of international skilled operators from EU. The team achieved several first places in the IARU Region 1 contest on VHF and UHF bands from 1997 through 2002, using multi systems antennas.
