QRP TTF 2013

For the 50th anniversary of the Vienna Wireless Society, the club operated under a special event call sign: W5O. As usual, there was a good turn out of club members for both the picnic and on-air activities. We put a couple rockmites, FT817s, and a KX3 on the air, and accumulated 62 contacts in our log in total running predominantly CW, but some phone as well. We had multiple contacts with other operators also participating in the QRP TTF, but also the Florida QSO Party, and one SOTA station. In the next couple weeks, we should send out our QSL cards to confirm the contacts.

The antenna was based on a design found on the blog of KI6SN, and I summarized the construction details for my effort on a Google-plus post.

After spudgunning two trees, we hoisted the folded dipole to a flat 40-foot deployment. The feed line is about 25 feet, so a short BNC-terminated coax extension was used. The antenna worked great and allowed us to work a Swiss station, and to score reverse beacon hits throughout Europe on 20m.  I swept the antenna with a MFJ analyzer at the end of the event, and noted that SWR was below 1.2 for the entire CW portion of the band, and less than 2 from below 20m to above the voice portion of the band. So, quite impressed with the folded dipole design. As advertised, it packed up easily and without tangling.
