I am not sure how you got what you said from my one paragraph about 2 meter gear...but I can put you at ease in that most of what you are saying I would agree with...my point however for the "average" ham I stick by.
We do use 10ghz here a bit...all our repeaters are controlled or cross linked by either a 3 or 13 centimeter link. Robert WB5MZO
