GB3HV

GB3HV has Moved

We left our lovely Farnham site before Christmas 2021 but the good news is that Roy G8CKN has offered to host 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 Reopeater Group.

The proposed Constitution is here: Media:20250423 GB3HV REPEATER GROUP CONSTITUTION.pdf

The proposed Site Agreement with R & J Powers is here: Media:20250423 GB3HV Site Agreement.pdf

Tese documents will be discussed at the inaugural meeting of the GB3HV repeater Group which will take place by Zoom on Tuesday 29 April 2025 at 8 pm. Details from G8GTZ or G8GKQ.

Equipment and rebuild

GB3HV has been rebuilt and is now digital in, digital out. 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 10,499.25 MHz on QO100.

Inputs and outputs

GB3HV receives on:

70cms: 437 MHz DATV on 1MS and 333kS with a steerable beam.

23cms: 1248 DATV on 2MS, 1MS and 333kS with asteerable beam.

GB3HV also has a stream input - contact G8GTZ or G8GKQ for details
