I don't but have flown microlights down that way a lot.
Hampshire Microlight Club is basically a friendly association of private owners across a few strips. So, don't expect great things - but equally don't give up trying to contact them. But, for instructors and club aircraft you're better trying Popham or Old Sarum.
Also look at Chilbolton - a reasonably healthy club on a single site near Andover. Agsin howevever all aircraft again are privately owned and any instruction is from a couple of local freelancers.
