All the repeaters and beacons are funded solely by donations from their users and supporters. There is no club or group to join and no annual membership fee. We rely totally on your good will and generosity.
Located in South Wiltshire, close to the junctions of the A303 and the A350, they provide coverage across many parts of Wiltshire, Somerset and Dorset. |
The following is something that we ALL need to take very careful note of, and act upon it accordingly.
The following is taken from the ETCC (UKRepeaters) web site, published 20th Feb 2017.
"POWER LIMITATIONS IN 70CMS
With the significant increase in numbers of 70cms digital voice repeaters which have inputs at the low end of the band the ETCC have been reminded to highlight the power restrictions which apply to 430 - 432 MHz.
The maximum peak envelope power in this part of the band is 40W (16dBW) effective radiated power (ERP) for Full and Intermediate Licensees and 10W (10dBW) for Foundation Licensees.
Given that many modern mobiles can run 50 Watts power output to high gain collinears it is very easy to exceed these levels, so please take care to keep your power to the minimum required and certainly never above the limits mandated in your licence."

GB3JB - 2m FM
Current Status: Fully Operational
Coverage map provided by ETCC at ukrepeaters.net
GB3JB is a simple to use, good old fashioned, basic 2m analogue FM, voice repeater, with no frills, bells or whistles. Neither is it connected to the Internet.
Channel RV63, 145.7875 Mhz output at 14 dBw (25w) ERP, 145.1875 Mhz input, 103.5 Hz ctcss tone. The ident is the Callsign + Locator, i.e "GB3JB IO81VC" The invitation to transmit is a single dit. There is no 1750hz tone burst access. The timeout is set to 3 minutes. Being on 2m, it has the greater stand alone coverage with towns and citys like Dorchester, Bath, Bristol, Salisbury and Yeovil, plus specific areas such as Salisbury Plain, the Blackmore Vale and Cranborne Chase being well within its range. Coverage significantly extends for fixed stations, across most of central and parts of North Wiltshire, Southern Dorset and West Hampshire, plus parts of North and West Somerset. Coverage is of course dependant upon the users actual location, topography and installation, as is the case with all VHF / UHF communications. |
GB7JB - 70cm DMR
Current Status: Fully Operational
Coverage map provided by ETCC at ukrepeaters.net
GB7JB is a Digital Voice Repeater, based on DMR TDMA technology. Thus providing the significant benefit of two simultaneous communications channels, or slots.
Channel DVU37, 439.4625 Mhz output at 14 dBw (25w) ERP, 430.4625 Mhz input, Colour Code 1. The ident is the Callsign + Locator, i.e "GB7JB IO81VC". This is sent in analogue FM. The timeout is set to 3 minutes. Slot 1, which only accepts Talk Group 9, is intended as a local natter channel, much the same as any other 70cm repeater. However Slot 2, which only accepts Talk Group 950, is linked into the South West Cluster, which additionally consists of GB7AA, GB7BS, GB7CW, GB7ED, GB7DR, GB7KT, GB7MJ, GB7SD and GB7YS DMR repeaters. 
Accessing GB7JB via slot 2, means that your signal will automatically be re-transmitted, not only by GB7JB, but also by the other repeaters of the SWC, thus providing significantly greater opportunities for contacts as a result of the combined coverages.
The South West Cluster of DMR Repeaters is an independent network of repeaters that is NOT centrally controlled or funded. Coverage is of course dependant upon the users actual location, topography and installation, as is the case with all VHF / UHF communications. |
