HAM Radio UHF frequency North America East Coast PAVE Phased Array Warning System (PAVE PAWS)

PAVE PAWS is a United States' Air Force Space Command radar system for missile warning and space surveillance youtu.be/uuJTWM69ZqI

I have always wondered why UHF frequencies are not used for DMR or any HAM radio in the North East Coast of North America. PAVE PAWS uses frequencies located at the lower portion of the UHF spectrum near the Amateur Radio Band.

The PAVE Phased Array Warning System (PAVE PAWS) was an elaborate Cold War radar and computer system developed to "detect and characterize a sea-launched ballistic missile attack against the United States".

With the first solid-state phased array deployed, the system at the perimeter of the contiguous United States used a pair of Raytheon AN/FPS-115 Radar Sets at each site (2 sites in 1980, then 2 more used 1987–95) as part of the United States Space Surveillance Network.
