Many of the articles below refer to operation at LF and MF under Experimental Service authorizations from
2004 - 2017. The FCC has now created Amateur Radio bands at 2200 and 630 meters. To prevent possible interference with power line carrier services which
may operate in those bands, you must file your geographical information with the Utilities Technology Council. Go to:
https://utc.org/plc-database-amateur-notification-process/ for more information. If they do not object within 30 days, you are clear to begin operating
according to FCC Part 97 rules.
