There is no rule or regulation that says these frequencies must be "transmit blocked", and, nobody asked anyway..Stop making up lies, its making you look ignorant.
I do not recall the exact name of it, but there is a Menu Setting that you can change to show name, frequency or channel.. Might be called MDF or something like that.. Find it, then set it to 'name'.
Me too... I HAD two brand new RT97L's that I could have used to test this.. but I gave them both away.. Now i'm kicking myself and I wish I was not so kind, unselfish and loving toward my fellow-man...
Never again!
The only way to know for sure is to put a meter or portable antenna analyzer on it and test it..
But, like the @mb523 said, its not going to work very well.
