This page is devoted to Fox Hunting and Amateur Radio Direction Finding (ARDF) in northeastern Massachusetts. Foxes are hidden in conservation areas and other public places almost every week in the spring, summer, and fall. Announcements of where and when to start looking are made via email, so be sure to join our email list (see below) to get the latest information.


Conservation Areas and Trail Maps

Most towns in northeastern Massachusetts have conservation area trail maps available online. Click the town link below to access these maps.

Acton. Click on the left sidebar list.
Westford. A book of maps of Westford conservation areas can be purchased for $5.00 at the town clerk's office at Westford city hall and at the Roudenbush Center.

OpenStreetMap has trail maps available
here. This site requires a login, but is free.

Fox Finding Facts

  • Foxes on the loose are announced on the NE Mass Foxhunters email list. To get on the list, see the instructions at the bottom of this page
  • Most two meter foxes transmit on 146.565 MHz. Occasionally an 80 meter fox is hidden; the email announcement will have the frequency of this fox.
  • Foxes with voice announcements use the Squawkbox module, which typically transmits a short (e.g. 30 second)  voice message and repeats once per minute. The low power output of about 50 mW allows more than one Squawkbox to be on the air if they are far enough apart.  Often, one will operate in Westford and the other in Littleton simultaneously.
  • Other two-meter fox boxes use the Byonics module which sends a series of tones for a fixed period (e.g. 30 minutes) when activated by the hunter sending a DTMF ‘2’ for two seconds.
  • Some of the foxes use an HT transmitting 1 or 2 watts, in which case we usually just announce the town it is in to practice long-distance direction finding similar to what we would need to track down a repeater troll.

Build an Antenna for Two Meters

A two meter fox hunting antenna can be built for about $15 with PVC pipe and fittings from Home Depot or Lowes. Building instructions are available here. A YouTube video of how to build it is here.

You'll also need an "offset attenuator" for your antenna. Attenuator sources include:
A complete antenna and attenuator kit is available here.

80 Meter Fox Hunting

Hunting foxes on 80 meters is actually much easier than on 2 meters because the 80 meter signal doesn't reflect like the 2 meter signal, and the 80 meter fox with its antenna is usually large and easy to see. The 80 meter receiver and antenna is (believe it or not) MUCH smaller than the 2 meter system.

Receiver systems for 80 meters include:
  • R3500D available from China. Information is here.
  • The RigExpert FoxRex 3500 has been discontinued, but is sometimes available from DXEngineering here.

Own Your Own Fox

You may want to have your own fox so you can hide it and challenge the hunters. The Homing In site has instructions on how to build a fox, or you can buy one from these vendors:
  • Byonics sells two foxes.
  • DopplerDF sells the SquawkBox and MicroHunt transmitters

Hunting foxes on the conservation trails can be hazardous! Recommended safety precautions include:
  • Protect against ticks and other insects. Treat your clothes with Permethrin at the start of the season. Use a good insect repellant and inspect for ticks when you're out of the woods. When you get home, take a shower and throw your clothes into the dryer for at least 15 minutes on high heat to kill any ticks that may have hitched a ride home with you.
  • Carry a bottle of water.
  • Print a copy of the trail map and carry it with you.
  • Wear a hat and use sunscreen.
  • Most cell phones have the capability to remember where you parked your car. Know how to use this feature and be sure it's enabled.
  • Cell phones sometimes lose a signal in the woods. Carry an extra HT with an extra battery and monitor a local repeater. The WB1GOF repeater (146.955 pl 74.4) has good coverage in Westford and surrounding communities, so do a radio check on it or another local repeater before you start hunting and monitor the frequency.
  • The conservation trails are usually well marked. Remember the designation of the trail you start on and always look for landmarks so you can recognize the way back to your starting point.
  • Call for help if you're lost or injured!

What Do Foxes Look Like?

Foxes don't want to be found! Here are pictures of what you're looking for:

This fox is pretty obvious. Foxes are usually covered with leaves, and only the antenna is visible. There may be a log book with the fox for you to enter your call and time of discovery.

Yes, there is a fox in this picture. Can you see it?
