I placed out two fox boxes this morning.
One is the 2 meter 146.565 DTMF tone 2 to activate. The second one is a 70 cm 432.300 DTMF tone 2 to activate.
Both foxes are hidden in Westford at the Mass Audubon [Nashoba Brook Wildlife Sanctuary] off Rt 225 near Powers Road.
I don’t know how long the batteries will last; maybe a few days.
