[Harp-L] wireless frequency changes

[Robert Hale]

I pitched this before, and received no comment.

My Samson CR77 is Channel N5 - 645.500 MHz, And Sweetwater (for example)
announces "no longer available."
There must be a bunch of us using wireless mics performing with harmonica.

I read one example where a cell phone user in an off-Broadway theater
created a constant tone in all house wireless mics, then agreed to shut off.

When and how is my mic going to be useless?
What frequencies do I need to shop next?
