The significance of the question is to attempt to proof my notion that the "cover" method is mostly used at public fields as a way to manage the missing 'pin' problem.
So, you yourself have discussed the inadequacies of your current method of freq control.
Does knowing that there are a lot of fields using the covering method fix that? NO!
Does knowing more flying clubs use the same freq control system save planes from getting shot down? NO!
Does another poll fix these inadequacies? NO.
Are you going to solve your problems here? NO!
Would updating your old freq system to a new system that is more safe solve all of your shoot downs? No, but it will solve some of them.
Why don't you just fix the problem and quit talking about it. It isn't going to go away no matter how many clubs use it.
You can sit and whine about it, or you can go think about it and design a better system. What kind of person are you, a fixer or a whiner?
