Hi LS
You know I get asked that question a lot. Answer is I haven't a clue.
No one else seems to know either. None of the CB forums (or even some other prepping forums) have run a decent poll recently, if at all!
I've had loads of folk say they've got one on the shelf or in the shed but to actually get it going again it seems too hard for today's mobile phone and PC mad world.
I'm told it's on the increase by other freebanders but it's not quantifiable.
Certainly round me it's not many. Still I've always preferred quality to quantity.
I asked my little mail order "dedicated CB shop" for a opinion.
They ship on average 15 CB units a week and freebanding sets about 1 a month.
So I'd guess round 750 units a year from a tiny dedicated shop.
Their 'visiting' customer base is in the 100's.
Our little FB group repair and are asked to "modify" 2 to 3 sets a month.
Deduce what you can from that.
Paul
