The FCC has adopted extensive changes to its rules governing experimental licensing. The ARRL filed comments (actually, reply comments) in this proceeding expressing concern about the increased probability of interference to the amateur services. An initial review of the attached Report and Order shows that the Commission backed away from some of its more radical proposals and even accepted a few of our suggestions. A new category of Program Experimental Radio Licenses will be available to qualified entities such as universities with accredited graduate research programs in engineering, research labs, and manufacturers with spectrum management experience that will permit much broader latitude to conduct experiments within a specific geographic area than is typically provided by a conventional experimental license. However, these licensees will be required to post technical details of the experiment in advance, to conduct due diligence in their local operating environment to identify any interference risks and to plan accordingly to avoid causing harmful interference to incumbent licensees, and to designate a "Stop Buzzer" point of contact with the ability to cease operation immediately in the event of harmful interference. I won't speak for Chris, but I am somewhat pleasantly surprised that the Commission seems to have struck a reasonable balance between the objective of facilitating experimentation and that of protecting incumbent users from harmful interference.
