Hmmmm..
"AIM 4-1-11 lists the frequencies assigned for air-to-air. If a frequency is not listed there, it is not to be used for air-to-air...it's that simple. And 123.45 is assigned for use by all aircraft manufacturers, not just Boeing. It is also used by Oceanic Control on some trans-Atlantic routes.
As far as making up one's own frequency assignments, what is to stop "everyone around here" from using 120.3, 131.75, 119.2, etc etc etc...those are not air-to-air frequencies either.
End of rant. Thanks for the kind comments."

Perfect... As a experimental homebuilt builder, I AM the( manufacturer), so as I read the rule I am allowed to use 123.45..
