GB7NB D-STAR Repeater Operational (14th Sept, 2009)
The Norfolk Broads D-STAR repeater GB7NB went live on Friday 11th September at 15:00 and the first QSO was with M0KXK Ray.
GB7NB has an output frequency of 439.6875 MHz with the input 9 MHz lower at 430.6875 MHz.
The group’s website says that intial reports were good however but there is an issue with drop outs which may be due to mixing products from other transmitters on the site.
Phase 2 of the project will be getting GB7NB connected to the gateway, this is well underway with the PC Server already built and tested and the Icom G2 s/w loaded thanks to Darren G7LWT.
More details on GB7NB here, and the Norfolk Repeater Group here.
