Guide to WB1GOF Repeaters
(23-Februrary-2010)
General Stuff:
·
All 3 of the
repeaters are located at the water tower at Prospect Hill
in Westford. The top of the tower antenna elevation is 579
feet/AMSL. The exact location is N42.34.36 W71.26.33.
Transmitters are located in the AT&T cell site. We are
running 55 watts on 146.955 and 18 watts on both 145.330
and 442.450 D-Star repeaters. As of February 2011, the
145.330 MHz antenna is about 90 feet BELOW the other 2
repeater antennas on top of the communications building at
the base of the water tower.
·
On 146.955 Mhz. Set your CTCSS encoder and decoder (if
desired) to 74.4 Hz.
·
Repeater ID is set
at 9.5 minutes, use it as your guide for your
identification, when you hear the repeater ID, then you
should ID and your station and the WB1GOF will always meet
the FCC requirement of 10 minutes between ID.
