 ====== GB7WIN Crab Wood, Winchester ======
-**GB7WIN is now INP3 only, we are hoping to be able to provide end-to-end NETROM connections to nearby nodes but we're still figuring out the gremlins :)**
 GB7WIN was commissioned on 23rd March 2025 by Alan G8IPG and Jason G5RKT as part of [[https://swhr.org.uk/|South West Hampshire Raynet's]] wider project to provide digital voice and data services to amateurs across the wider area and as a spiritual successor to [[nodes:gb7sou|GB7SOU]].
