 As far as possible we hope to use the forthcoming 6m port for linking and the 2m port for user access; with only the 2m port currently operational locked NETROM routes have been implemented to the following nodes with which we have a (mostly!) reliable circuit:
 [[nodes:gb7rdg|GB7RDG]] (Reading, Berks), [[nodes:gb7bsk|GB7BSK]] (Basingstoke, Hants), [[nodes:gb7wod|GB7WOD]] (Woodley, Berks) and [[nodes:mb7npw|MB7NPW]] (Pewsey, Wilts).
