The Williamstown Repeater “625”
146.625 -600 Khz
Status: On the Air
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), with spots of usable coverage south of the Randolph/Bethel area. The repeater also covers the Central Vermont area, including: Montpelier, Barre, Berlin, Middlesex, Plainfield, Marshfield, Northfield, Orange, Corinth, Groton and Calais. The Williamstown Repeater is linked full-time via RF to the Vermont Interconnect System.
The repeater is a Motorola MSF-5000 running at 110 watts. The repeater is connected to a Sinclair Technologies Q202 duplexer, which provides over 80db of isolation. 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.
In August 2018, this system was installed, replacing the club’s old GE Mastr II, which ran reliably for two decades.
