Notes: The repeater is located just South of Barre, VT and covers up and down the I-89 Corridor from Randolph (Exit 4) to Waterbury (Exit 10). The repeater also covers the Central Vermont area, including: Montpelier, Barre, Berlin, Middlesex, Plainfield, Marshfield, Northfield, Orange, Corinth, Groton and Calias. The Williamstown Repeater is linked full-time via RF to the Vermont Interconnect System.

The repeater is a GE Mastr II which runs 80 watts. The repeater is connected to a Sinclair Technologies Q202 duplexer, which provides over 80db of isolation. Receiver performance is improved with an additional preselector and GaAsFET preamplifier. All of this is connected to 7/8 hardline which runs to a 4-bay dipole, providing around 7dbd of gain. The link radio is a Motorola mobile radio, attached to a directional antenna on the building. All of this is controlled by a Link Communications controller.

As of July 2018, the Williamstown Repeater is in the early stages of being replaced with a Motorola MSF-5000.
