NSMA’s intent is to make the coordination process more effective and more efficient. To this end, NSMA recommendations represent guidelines that coordinators will find useful in supplementing the FCC’s coordination rules. NSMA reports and tutorials, on the other hand, are helpful ready-references or training manuals.

The following is a list of NSMA Reports and Recommendations that have been published to date. To obtain a copy of documents not on the web, contact the NSMA Secretary via email.
