 ====== GB7WIN Crab Wood, Winchester ======
-GB7WIN was commissioned on 23rd March 2025 as a joint project between Alan G8IPG and Jason M0MZF on the radio site at Crab Wood, Winchester, IO90hb 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. Thanks to Matt 2E0HKD for his continuing involvement in BPQ node configuration!
