The GB3VT repeater was licensed in 1980 and became fully   operational from its original site in December of the same year and then during   1995 and onwards from its present location co-sited with two other repeaters:   GB3ST on 70 cm and GB3SE on 23 cm.

The repeater transmits on 145.725 MHz and receives on   145.125 MHz, UK channel number RV58, although when the GB3VT repeater was first   licensed the original transmit frequency was 145.625 MHz, but later changed   frequency to help accommodate further newly licensed repeaters. Both the   receiver and transmitter use full decode and encode Continuous Tone Carrier   Squelch System (CTCSS) at a frequency of 103.5 Hz and the preferred method of   access is with the use of CTCSS. The Transmitter, Receiver and Repeater Control   Logic are all-purpose designed and home built, the time out is currently set at   3 Minutes. GB3VT also makes use of a purpose designed and home built 8 Cavity   Duplexer and the repeater delivers a total of 25 watts effective radiated power   (ERP) from a single colinear type   aerial.
