2010 World ARDF Championships
Jen and I attended the 15th World Amateur Radio Direction Finding Championships, September 13-18, 2010, in Opatija, Croatia. It was the first world championships to be held in Croatia, and the first to be held in the former Yugoslavia since the wars of 1991-1995. It was also the first ARDF World Championships with a separate competition for blind competitors. Except for the blind competition (which was held in a soccer field in Opatija), the competition areas were in the nearby Gorski Kotar, the most mountainous region of Croatia.
2010 USA ARDF Championships
Jen and I competed in the 10th United States ARDF Championships held May 21-23, 2010 in southern Ohio. This is the eighth USA championships that Jen and I have attended. The competition was held in two locations near the college town of Oxford, Ohio, the home of Miami University. This is the second time that the championships have been held in the greater Cincinnati area. Jen came home with gold medals in both W35 competitions, and Ken came home with silver medals in both M21 competitions.
2010 Bletchley Park Station X
During a visit to England in March, 2010, we visited Bletchley Park. The Bletchley Park National Codes Centre is the site of Britain's World War II efforts to break the secret codes of the Axis powers. Originally a country estate chosen because of its obscurity, the site at one point was filled with huts where scientists and technicians built and operated the first programmable computers. A group of local amateur radio operators has reactivated a radio station at the estate for the first time since Station X went off the air in 1940. We were fortunate enough to get after-hours access to the station, as we were there on a night when the radio club was meeting.
2009 K5TR NAQP Phone, August
I operated the August, 2009 NCJ North American QSO Party, Phone with George K5TR and Robert K5PI in the multi-operator, two transmitter (M/2) category from K5TR contest station in scenic Blanco County, Texas. Although I operate at the station several times a year, it has been a while since I took my camera out.

Jen and I attended the 14th World Amateur Radio Direction Finding Championships, September 2-7, 2008, in Hwaseong, Korea.

Korea has the fourth largest amateur radio population in the world, with about 140,000 licensed operators.Jen was a competitor in the W21 (women, any age) category, and I was an international juror.
2008 USA ARDF Championships
Jen and I hosted the Eighth USA ARDF Championships held May 8-10, 2008, in Bastrop, Texas. The competition was held in Bastrop State Park. As we were very involved in the organization and execution of the competition, we did not take as many photos as we have in years past.
2007 W5 DX Bash

2006 80 Meter Antenna
In February, 2006, I built a prototype antenna for Amateur Radio Direction Finding on the 80 meter band. The antenna is a shortened vertical, supported by a 20' telescoping fiberglass pole. The vertical is 5.5 meters tall, with a 55 cm tall loading coil of 170 turns at the top of the bottom section of the pole. It has two radials, each 5 meters long. It was designed with the help of the LOADCOIL software program by Reg Edwards G4FGQ.

Bryan Edwards W5KFT hosted his world famous W5 DX Bash held at his family's cattle ranch, on the shores of Lake Buchanan, about 70 miles NW of Austin, TX. This year, the gathering was much more informal than normal, as Bryan's recent back surgeries had made preparation difficult.
2004 ARDF Yagis
This year, Jen W5JEN and I built or rebuilt tape measure yagis for ARDF. I reused the PVC in my old tape measure yagi, added 5" to the rear of the boom, and used PVC pipe hangers to mount a plexiglass plate for the receiver. Jen built a new tape-measure yagi, using a modified fishing rod with a cork grip for the boom. The boom-to-element brackets were quarter-round wood trim, notched and epoxied onto the fishing pole. Her yagi is noticably lighter than mine.
2004 N5OT IARU HF World Championship
Due to my travel schedule, I was unable to operate the contest from central Texas.

This was my first HF contest effort from outside of the state of Texas.

While I was in the San Francisco Bay area on business, Dave and Barb Leeson had several of us over to their house for dinner. The Leesons live south of the town of Los Gatos, on top of a mountain at 3500' elevation. Dean N6DE, Trey Garlough N5KO, and I all arrived a little before sunset.
