After a fault with the GB3GH Transmitter. GB3GH is now back on the air and we will monitor and test it over the next few days to confirm it is fully working again.



GB3GH is a 70cm analog voice repeater operated (since 28/12/2001) from Churchdown Hill (located mid-way between Gloucester and Cheltenham) [IO81VU] at approx 150m above Sea Level.

A coverage map is available from the RSGB Emerging Technology Co-ordination Committee.

The repeater on Channel RB5 (433.125MHz Tx, 434.725MHz Rx – CTCSS Tone 118.8Hz ‘J’ ) has been operational since 1984.

Current equipment (since 26th February 2006) comprises a Tait 800 Series Transceiver, with PIC based control logic designed & constructed by Steve (G4FPV) and cavities constructed by the group, the antenna system is a small co-linear to give an ERP of 25 Watts (as permitted by the licence).
