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.
HOW TO USE REPEATERS
Operating using voice repeaters requires good practice to be observed, and ETCC
members are sometimes asked to indicate what is that practice. We also often
hear one operator complaining about some aspect of another’s operating.
Firstly remember that repeaters are licensed on an INDIVIDUAL’s radio amateur
licence (the KEEPER) even though they may be part of a larger umbrella
organisation such as the UKFM Group (Western) or the Central Scotland FM Group
for example. This means that this named person has the legal responsibility for
ensuring the station adheres to the licence conditions and is operating
The KEEPER may have to switch off the repeater in certain circumstances (Ed: or
implement a curfew to restrict the operational times the repeater is available
It is also worth remembering that repeaters are licensed for ALL radio amateurs
to use (provided that they operate within the terms and conditions of their
licences) whether or not they have contributed in any way to the upkeep of the
repeater or are members of the group. There are NO CLOSED REPEATERS and anyone
finding they are prevented from taking part should lodge a complaint to their
ETCC regional member.
Here are some key points which should help new and experienced amateurs alike
to get the best experience from using repeaters:
1.. The ukrepeater.net web site (web address included below) lists the
parameters for all UK repeaters – check the details first, and get an idea of
the coverage footprint.
2.. Check use of CTCSS tones – many repeaters need application of the correct
sub-audible tone for operation.
3.. If you are inexperienced it is worth listening for a while before actually
transmitting. This helps to give you an idea of who is around and what to
4.. Repeaters are designed to assist mobile and portable operation, though
fixed stations can use them, priority should always be to the mobile and
5.. Leaving a break after a transmission is important as it allows the talkthrough
timer on the repeater to reset, and also gives a convenient gap for new
stations to call in.
6.. The recognised calling protocol is “This is (your callsign) listening
through (repeater callsign)”
7.. If you find you can hear the other station on the input channel then
consider QSY to a simplex channel, especially if the repeater may be busy.
8.. Your callsign should be given with sufficient frequency to identify you,
though it would not normally be given on every over especially if these are
short and snappy!
9.. If the repeater is busy remember that many repeater sites have other
repeaters on different bands that might be worth checking out.
10.. Sadly, repeaters have always attracted anti-social and illegal use. If
this happens then the best rule is to ignore it. Leave the Keeper or those
empowered to deal with the problem the ability to record and track down the
mis-use. (Ed: Keying over the offending transmission with dead carriers often
destroys otherwise valuable recordings, plus breaks the terms of your own
Repeaters are provided by a dedicated group of radio amateur enthusiasts – if
you are a regular user on your local repeater then why not make a donation, or
join the group behind the repeater.
