 ====== GB7WIN Crab Wood, Winchester ======
-**Currently 2m only, temporary lash-up in operation :) **
 GB7WIN was commissioned on 23rd March 2025 by Alan G8IPG and Jason M0MZF 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]]. Thanks to Matt 2E0HKD for his continuing involvement in BPQ node configuration and to all the OARC packet community for helping us along the way.
