 ====== 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!

-  * If If XRouter uses obsolescence counters and resets them after receiving a unicast scheduled info, whereas BPQ sends no scheduled info, only updates, can the two interoperate INP3 currently?
