Where do I sign up for a reserved frequency that everyone will avoid? I'm sorry, but these were not created to be "reserved" frequencies nor were they created in order to avoid clashes. They were created with the knowledge that automatic stations would create interference and that limiting the frequencies/bandwidth would reduce the interference potential. One of the desires of the FCC when they created these bands is that over time, technology and procedures would develop to reduce the interference to a minimum. Sad to say that nothing has changed from the time the automatic sub-bands were created and has even gotten worse through the use of modems that expand their bandwidth with no regard to adjacent frequency usage.
