As per the 433 Alive Facebook Group:
The next 433 Alive event will run from 12:00 to 15:00 BST (11:00 to 14:00UTC) on Sunday 23rd August 2026 . Times are not critical,its all about creating activity, although I would probably advise against calling CQ on 70cm at 2am in the morning 
Its not a contest, so can just pop in and out at your pleasure and no special information needed. Having said that, knowing your locator square does allow me to draw pretty maps after the event
I have alerted for G/SP-017 Billinge Hill again for this one.
Also hoping to fit some 2m SSB and 23cm activity in as well.
Hope to work a few of you on the day.
Ian
