Map showing GB7WS coverage
GB7WS has now been operational from Billinghurst since early summer 2023.
Sadly the repeater keeper, Mick Senior G4EFO became SK in late December that year. It was always Mick’s intention that the Horsham Amateur Radio Club (HARC) should take over the management and operation of GB3WS, GB3HO and GB7WS. Accordingly, the HARC Chairman, Adrian (G4LRP), now holds the official Notice of Variation for each repeater from Ofcom.
GB7WS is using a Motorola DR3000 repeater unit running 6 watts.
Single antenna working for GB7WS is achieved by a Procom 9-13 MHz spacing duplexer. Each side of the duplexer produces a notch of around 70dB at the unwanted frequency, with an insertion loss at the wanted frequency of about 1.4dB.
The aerial is a Diamond X-200 dual band co=linear aerial with 6dB gain mounted on the chimney of the house at about 10m.
