GB3JB is NOT closing down or moving location

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.

The site, which is powered by Solar and Wind energy, is located close to the junctions of the A303 and A350, in south Wiltshire.

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 70cm Digital Voice Repeater, based on DMR TDMA technology. Thus providing the significant benefit of two effectively simultaneous communications channels, or slots.

The repeater is located in the Town of Wincanton, in Somerset.

Channel DVU37, 439.4625 Mhz output at 14 dBw (25w) ERP, 430.4625 Mhz input, Colour Code 1.

The ident is the Callsign, i.e "GB7JB". 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, GB7DR, GB7KT, GB7SD and GB7YS DMR repeaters.

Accessing 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.
