I agree 100%. 
Need a "boiler plate" write up  that can intelligently and succinctly state our concerns. 
Much appreciated.

A suggestion:  Many of us understand the basic problem but are not good at framing the issues in the right technical language or giving the FCC what they are asking for in their request for comments.  Perhaps some among us who feel competent in these areas could post a proposed comment on this reflector that could be used by others as the basis of a comment filing.
