The two related actions that we have been waiting for to gain Amateur access to the 2200m and 630m bands have happened. First, the Office of Management and Budget has published its approval of the FCC Report and Order in the Federal Register:
https://www.gpo.gov/fdsys/pkg/FR-2017-09-15/pdf/2017-19578.pdf
Second, the Utilities Technology Council has added a notification form to its web site, allowing U.S. Amateurs to submit their information:
https://utc.org/plc-database-amateur-notification-process/
The OMB approval sets the effective date of the regulations as September 15, 2017. Otherwise, it is just interesting reading. The really important thing is to go to that UTC website page and submit your information. That starts a 30 day clock for you. If you do not receive a rejection from them in that time frame, then you are free to begin using these bands at the end of the 30 day period.
More details are likely to surface in the coming weeks, so stay tuned to this page or the various email reflectors.
