GB3HV has Moved and is now on-air from IO91LD
We left our lovely Farnham site before Christmas 2021 but the good news is that Roy G8CKN is now hosting the repeater at his QTH in IO91LD - this is a great site with different coverage to Farnham but we are hoping all of you will still be able to access it.
Organisation
GB3HV will be managed by the GB3HV Repeater Group.
The Constitution is here: Media:20250423 GB3HV REPEATER GROUP CONSTITUTION.pdf
The Site Agreement with R & J Powers is here: Media:20250423 GB3HV Site Agreement.pdf
These documents were discussed and agreed at the inaugural meeting of the GB3HV repeater Group on Tuesday 29 April 2025. The record of the meeting is here: Media:20250429 GB3HV Repeater Group Formation Meeting Record.pdf
Equipment and rebuild
GB3HV has been rebuilt and is now digital in, digital out (with a 23 cm analogue RX). This has been made possible by the great work done by Dave G8GKQ on the BATC repeater controller project which uses HDMI video switchers - see https://wiki.batc.org.uk/Repeater_Controller
The Tuesday net at 8pm is still very active with a number of stations either coming in by the stream rxr or relayed in by other users receiving 10,499.25 MHz on QO-100.
Inputs and outputs
GB3HV receives on:
70 cms: 437 MHz DVB-S or DVB-S2 at 1MS and 333kS with a steerable beam.
23 cms: 1248 MHz DVB-S or DVB-S2 at 2MS, 1MS and 333kS with a steerable beam.
23 cms: 1248 MHz FM with a steerable beam.

- 70cm RX 11.5dBd (13.6dBi) 'J-Beam' Multi-beam antenna. H polarised.
The Talkback and DTMF control is vertically polarised. 2m/70cm X-30A Dual Band Collinear. 3dBd/5.5dBd (5.1dBi/7.6dBi)
Transmit antenna: 23cm TX 6dBd (8.1dBi) Antec Omnidirectional 'Plate' Array. [Radiating 50W ERP]. H polarised.
Financials
A lot of the rebuild has been made possible by 2 generous BATC grants but going forward we will looking for a small annual subscription (currently £20) to cover the costs (including power) of operating at Roy’s. Please contact the Treasurer, Justin G8YTZ at justin.cockett@me.com
