The 420 through 450 MHz Amateur Radio Band is shared with the U.S. Air Force and they are the Primary user, the Amateur Radio Community are secondary users and it's been that way for decades. Their is a FCC Mandate that limits the ham radio operators on the UHF Band to 50 W output Maximum because of the Air Force's PAVE PAWS Radar System.
Important note: This 50W restriction applies only to a specific geographic areas. See Part 97, Section 303, Paragraph (m)(2) and Part 97, Section 313, Paragraph (f). |
