Located in the conservation land off Hartwell Avenue in Littleton, MA. Frequency of 146.565 with a 30-second voice every minute, runs continuously, no need for a tone.
You will not hear it in the parking area as I have modified the antenna (actually a 52 ohm resistor) and the signal is really weak until you get quite close, more of a challenge this way?
I forgot the log, so if you find it either take a picture or describe the location.
Happy hunting!
