The South Hampshire Repeater Group has recently established an on-demand link between the Fusion 70cm repeater GB7MT (Southampton) and the Fusion 70cm repeater GB7PO (Portsmouth) relying solely on RF. Whilst it is often common practice to use the Internet to link repeaters, the keepers of GB7MT and GB7PO decided to adopt an ‘RF only’ policy to linking their repeaters using off-the-peg (well, almost) Ubiquiti 5Ghz equipment.
The 13-mile hop between sites is achieving bandwidth in excess 100Mbps of which the repeaters use approx. 0.05Mbps! The idea was initially inspired by the Local Emergency Planning Officer Tim Pettis 2E0CXQ who, for resilience purposes was keen to establish a communications path between the two cities in the very unlikely event of an existing civil communications infrastructure outage.
The group would like to thank Karl Brazier G7AFT of Yaesu UK who offered technical guidance and that all-important inspiration!
