When did you start doing ARDF? Who introduced you into ARDF?
"Since I was a kid I have been an active homebrewer, always looking for things to build or improve. Six years ago at a ham-fair I bought a PLL-circuit and thought 'this would be nice for a portable radio or maybe ARDF receiver'. So I read a book on foxhunting, built what I thought was a good receiver, and, to try it out, went to my first foxhunt. It was a desaster! But it was also fun and I got a lot of encouragement from experienced ARDFers, so I stuck with it and gradually improved my equipment and my technique. From the beginning I published all my ARDF designs on the Internet, and they are now very popular homebrew projects in Europe."
Why do you like doing ARDF?
"I like building things. I like being in the nature. I love the excitement of searching and finding hidden transmitters. And it is always fun to spend time with other ARDFers, because they are as crazy as I am."
As a team Canada member what experience do you expect from upcoming World ARDF Championship in Croatia?
"I feel very honored that I have been invited to be a member of Team Canada. Realistically I have no chance to get close to a medal. So I see this more as a social event, a chance to meet old friends from all over the world and to make new ones. This is my first World Championship, so I am very much looking forward to the experience. And although I will not be world champion, I will definitely challenge my American friends and my German training partners."

Amateur Radio Direction Finding - by G. D. (Joe) Young, VE7BFK
Introduction
Amateur radio direction finding (ARDF)—also called Radio Orienteering, foxhunting, or transmitter hunting—can take many forms. The game described here has been standardized and fostered by the International Amateur Radio Union since about 1978. The object is to locate and visit on foot each of up to five transmitters concealed in a wooded area in as short a time as possible by using a directional receiver to obtain bearings to the transmitters. The transmitters (foxes) all transmit on the same frequency, but take turns transmitting a unique signal for one minute and are silent for 4 minutes while the others transmit.
The skills needed to succeed include obtaining accurate bearings with the receiving gear, navigating through the wooded area using map and compass, and devising a strategy to visit the required sites in the minimum time.
Course layout, rules
See Figure 1 for a (schematic) course layout. The hidden transmitters, foxes, will be located so that the associated marker flag (control) can be seen when the hunter is within about 3m of the transmitter; they will be at least 400m apart; no fox will be nearer than 750m from the start. A homing beacon on a different frequency from the foxes is located at the entrance to the finish corridor.
Each fox will transmit a signal with a unique pattern that identifies which transmitter it is. The standard patterns are incidentally slow Morse code characters, but you do not need to know that to understand which fox is on. The signals have two long (dashes), three long (dashes), then followed either by one short (dot), two short, three short, four short, or five shorts to indicate fox 1, 2, 3, 4, or 5 respectively. In addition to the transmitted patterns, a fox can also be identified by the time it is on: fox 1 transmits in minute 1, fox 2 in minute 2, and so on. The beacon transmitter sends two long, three long, continuously. Finally, to comply with radio regulations, the transmitters will also send an amateur radio call sign in rapid morse code at the beginning of each transmission.
Prior to any competitor being on the course or starting of the foxes, it is usual to gather the receivers in a quarantine area near the start. When there are many competitors, they will be divided into groups of 3 to 10 and the groups start at 5 minute intervals to spread competitors out in time. A few minutes before the start, the competitors will receive a map of the area and any last-minute info about the course and will pick up their receiver from the quarantine. The receivers must remain turned off while awaiting start.

A few minutes before the start, the competitors will receive a map of the area and any last-minute info about the course and will pick up their receiver from the quarantine. The receivers must remain turned off while awaiting start.
The hunter will leave the start position when instructed to do so, go to the end of the marked start corridor (about 100m long), turn on the receiver after passing the end of the corridor and begin to locate the foxes. At each fox, the hunter will punch his score card with that fox's unique punch to prove having visited that fox. After locating all the foxes required, or as many of them as there is time for, the hunter exits the course via the marked finish corridor.
The time elapsed from leaving the start position until reaching the finish line is recorded along with the number of transmitters successfully located to determine the hunter's standing with respect to others in his category. The standing is first among those finding all of the required foxes in the shortest time, then among those finding one fewer fox, etc. Those not returning to the finish within the maximum time limit (2 hours, typically) are disqualified.

Few questions to Amel VA7KBA (by Matthew VE7UDP)
Every few weekends, enthusiasts from around Greater Vancouver (British Columbia) converge in local parks to sharpen their radio orienteering skills by hunting down hidden radio transmitters, and Amel is always one of them. To Amel VA7KBA, fox hunting is a sport that challenges the mind and body. Amel started hidden radio finding in his youth in his home country of Bosnia. Amel wanted to share his passion and his skills so he recently formed an ARDF group BCRadioSport whose mission is to promote the sport and develop radio direction finding skills in BC. He was heading to Victoria to do practice with the FARS Canada group there but wanted to see more people in the Lower Mainland pursuing the hobby.
1. When did you start doing ARDF? Who introduced you into ARDF?
"I started fox-hunting when I was seven. My father Almas (E71W, ex.T91W, 4N4DA, 4N4WF, YU4DA) took me to the national ARDF YU competition in 1979. He gave me an 80m sniffer and said I was going to compete, and then explained how the hunt was supposed to be done. I found all 3 foxes and finished 7th although I was the youngest competitor in that category."
2. Why do you like doing ARDF?
"Technology is one of my passions. I like being around technology. I also like being outdoors. What better way to do both things at the same time?”. “Each fox hunt is a new experience, hiding stations is different – each hiding spot has unique challenges and there’s always something new to learn. Also social aspect – meeting other people while playing with technology is very important to me too”.
3. As a team Canada member what experience do you expect from upcoming World ARDF Championship in Croatia?
"Meeting friends and people from all over the world. Gathering information on how to organize a big ARDF competition (Vancouver will be host in 2013 for IARU Region II ARDF Championship). Competing and doing my best to represent the country."

Few questions to Les VA7OM (by Amel VA7KBA)
Last year, about this time, during the SARC fox hunt in Surrey, I met Les. He came and introduced himself to everybody. He was asking about fox-hunting gear and I could "smell" someone who used to do the fox-hunting in the past. He tried VK3YNG MK4 (2m band) receiver. I didn't see him for a while until beginning of this year when he visited our another fox-hunt event. He showed even more interest in what BCRadioSport has been doing in Lower Mainland, BC. Les lives in Maple Ridge and belongs to the local radio club. He was so enthusiastic as he started talking about how he built 80m receiver, a prototype and how he wanted to try it. At that moment it was clear that Les was the person to recruit for not only the BCRadioSport mission but also for Team Canada which was just forming for the 15th ARDF World Championship. I asked him to join us and he accepted it. I am so glad Les is member of the team as he has shown (even after so many years not competing) that he is still a true champion. He is a super nice guy, very approachable and with excellent technical knowledge.
Recently I asked Les a few questions:
1. When did you start doing ARDF? Who introduced you into ARDF?
"In 1966/67. First I became interested when I saw an article in a magazine about fox hunting. It was in my native Slovakia. I was then 15 years old. But I learned the sport later when I joined the local radioclub OK3KTP in 1966. The radioclub was preparing a local 80m foxhunting competition. I joined the foxhunt with a borrowed receiver. The receiver was not working properly, I heard only one fox and could not find the direction as the sensing antenna was not working. That time I decided that I will build a better receiver."
2. Why do you like doing ARDF?
"I like ARDF because it is challenging – requires constant improvement of receivers, tactics, physical condition, work with maps, as well as building transmitting equipment and antennas. Doing ARDF I meet lots of new friends that have the same hobby. In Slovakia after first two courses (80m and 2m) we were running the third course – drinking contest and partying, and there we had lots of fun."
3. As a team Canada member what experience do you expect from upcoming World ARDF Championship in Croatia ?
"I hope to find all 3 foxes in my category and get back within the time limit. The competition will be very strong so I expect to end-up somewhere in the second half. I am looking forward to see some of my old friends that we were competing together as well as to meet new ones. I hope that this is better. I am working on my new 80m receiver and hopefully will finish it for the Victoria foxhunt."
