Andy Stewart, KB1OIQ writes on PART of Westford email list: Hi Everybody, I have deployed both the 2m fox and the new 80m fox! Both are located within a 1 mile radius of my home. My info is good on QRZ.com. There is no logbook. However, cell phone photos are accepted as “proof” that you found the fox(es). 🙂 Have a lot of fun, and 73, AndyRead More
John Salmi, KB1MGI writes on the PART of Westford list on April 28, 2018: I placed the 2 meter 146.565 fox box at the Audubon land off Route 225 (in Westford). It should be easy to find. It’s within site of the parking lot. Press DTMF tone 2 to activate.Read More
Andy Stewart, KB1OIQ writes on PART-L: Mark your calendars for Saturday morning, April 21st, at 11 AM. We will hold a fox hunting training exercise at the Westford Town Common, which is across the street from the JV Fletcher Library, 50 Main Street. The rain date will be Sunday morning, April 22nd, at 11 AM. What is a “fox hunting”? Otherwise known as “Amateur Radio Direction Finding”, fox hunting involves locating a hidden transmitter. We’ll hide the transmitter, and you’ll find it. No license is needed to find the transmitter, so ANYBODY can do it! John (KB1MGI), Andy (KB1OIQ), and anybody else who wants to help …Read More
Andy Stewart, KB1OIQ writes on the PART of Westford list: I have built an 80m fox transmitter and plan to deploy it once spring arrives. I also have two ARDF receivers for 80m. Very preliminary testing shows that the fox can be heard on 3.5805 MHz at least 3/4 mile away on slightly hilly terrain. This fox transmitter consists of an Arduino, which I programmed for this project, and a Cricket 80a (an 80m QRP CW transceiver). It runs off of a 9.6V NiMH rechargeable battery. More detailed information and the Arduino source code, can be found at https://sourceforge.net/projects/kb1oiq-ham-radio-projects/files/80m_ardf You have time to get your 80m fox receivers before …Read More

– The fox will be a stationary ham radio operator in a vehicle transmitting on 146.19 MHz PL 146.2. This is the input frequency of the MMRA Weston repeater (146.79 PL 146.2).
– The fox will be located within 10 miles of the Weston repeater which is at North 42deg 22.8′ West 071deg 19.2.
– The signal from the fox must be strong enough so the fox can be understood on the repeater output.
– The fox will transmit for at least 30 seconds of every five minutes during the fox hunt. The fox hunt begins at
10:00AM and ends when either there are no more hunters who have not found the fox or noon.
– The fox must continue to transmit on the hunt frequency throughout the hunt. However, hunters are prohibited from
transmitting once they have located the fox.
– The fox must not be on private property. In order to be found the fox must not require driving on private roads.
– Cooperation among the hunters is encouraged. Sharing initial direction bearings and signal strength
observations is necessary to allow some localization (for example the town where the fox in located) so that finding
the fox within the time limits is more likely.
– Home stations are also encouraged to participate and share their readings. As the hunt progresses, information
sharing is less valuable.
– Information is generally shared via the 2M repeater used for the hunt (in this case 146.79 MHz PL 146.2). Many
hunters use 70-cm to talk and to hear what others are saying as their 2-Meter radio may be dedicated to RDF on
the repeater input frequency.
The MMRA 70cm HUB1 repeater in Marlboro will be linked to during the hunt. Hunters therefore may transmit on either
2-meters or on 70-cm to join in the conversation. HUB1 repeater output is 449.925 PL 88.5 and the input is
444.925 PL 88.5.
As the hunters approach the fox conversations often shifts to 446.0 MHz FM simplex.
– We plan to have lunch at a restaurant near the fox location after the hunt. Lunch location will be a
consensus decision of those hunters who have found the fox.
– Ham radio operators who do not have equipment or who would like to gain experience from riding with an experienced
fox hunter are invited to ride along.
It is expected that each hunter will start from separate locations (as determined by the hunter).
Contact firstname.lastname@example.org (Kevin) and email@example.com (Bob) to coordinate ride alongs if needed. Those hunters who have room and are willing to accommodate riders are also asked contact K1KWP and N1BE.

Tom Charbonneau, NZ1X writes on the QRA mailing list:
The next [Quannapowitt Radio Assocation] fox hunt will be held Thursday night, March 27, starting at 7:00 PM from the Senior Center in Reading. Alex Svirsky, N1PRW, will be in place as the fox at that time using his new foxbox transmitting on 146.565 MHz. We will talk with the fox as necessary on the 145.290 repeater in North Andover. This should be more enjoyable than previous hunts because the foxbox will automatically transmit periodically (and fairly frequently), and we won’t have to keep making requests for the fox to start yapping so we can get a fix on him.
Hope to see you there,

[The Quannapowitt Radio Assocation] will have a 2 meter fox hunt on next Wednesday, October 10, starting from the Senior Center in Reading at 7:00 PM. It usually takes about 15 minutes to line people up in cars, so that we should get rolling by 7:15. That means that if you arrive later than that time the parking lot may be empty, so please try to get there by 7:00.
(If you don’t have a radio and/or directional antenna, you’ll want to go in a car with someone who does.)
We will use the frequency of 146.500 as usual (simplex of course). A compass and a map of the area will help. My cell phone number is 781-258-0625 if you need to call me. Also, I’ll be monitoring the 145.290 repeater prior to the fox hunt.Read More

[The Quannapowitt Radio Assocation] will have another 2-meter fox hunt on Thursday, July 26 at 7:00 PM, starting from the Senior Center in downtown Reading (where QRA has its monthly meetings). Tom Cefalo, W1EX, has volunteered to be the fox for this hunt. We will be using a frequency of 146.500 MHz. Hope to see you all there.Read More
The Quannapowitt Radio Assocation will hold a 2-meter fox hunt on June 21, 2007 at 7:00 p.m. Participants are invited to meet in the parking lot of the Reading Senior Center, 49 Pleasant Street, Reading, MA.
“Even if you do not have a directional antenna, you can still participate and have a good time,” writes QRA’s Tom Charbonneau, NZ1X. “Some of us have built a popular 3-element tape measure beam that stows easily in the trunk or back seat and can take a beating. It costs less than $10 to build and works well. I urge you all to build one.”
According to Charbonneau, QRA plans to hold fox hunts on a regular basis.Read More
Members and guests of the Quannapowitt Radio Assocation participated in a radio direction-finding “fox hunt” and also, were treated to an exceptional meal at the home of Tom Charbonneau, NZ1X on May 29, 2007.
According to QRA’s Bob Reiser, AA1M, he and Ron Draper, WA1QZK hid on a hill near the Stoneham-Reading town line near Route 28. “There was a small problem with the leads on the power supply in the repeater Ron set up, but this was bypassed and the hunt began.”
According to Reiser, the “foxes” were first found by WA1RHN, then a bit later by N1PRW and KB1OZS. All participants finally surrounded the target by 9:45 p.m.
“This was the first fox hunt held by the members of QRA in quite a while,” reports AA1M. “Everyone had a great time and Tom, NZ1X mentioned that maybe next time we will do it on a weekend day so all the participants can get home at a reasonable time.”
