See the Overview section for the RF systems. Power There are 3-phase mains power circuits which are wired into the radome pedestal for powering motor drives and RF power amplifiers. They are controlled by the disconnect switches on the wall in 54-2101, which have lock-out-tag-out safety systems to prevent RF and motor power being switched on while people are working on the radome.

To prevent these hazards, a safety lock-out-tag-out (LOTO) lock system attached to the 3-phase power disconnects power to the RF power amplifiers and the motor drives. text/html 2026-01-16T04:11:22+00:00 Anonymous (anonymous@undisclosed.example.com) http://radome-wiki.mitrs.org/dokuwiki/doku.php?id=sidebar&rev=1768536682&do=diff Getting Started History Mechanical Electrical Networking and Compute RF Systems Safety text/html 2026-04-08T01:31:55+00:00 Anonymous (anonymous@undisclosed.example.com) http://radome-wiki.mitrs.org/dokuwiki/doku.php?id=start&rev=1775611915&do=diff Radome Wiki [Installation of the new radome on November 5, 2022. Taken by Ron Hoffmann, N1XU.] The radome is a 27-foot composite sphere (Essco S27-83) on the roof of MIT building 54 containing an 18-foot circular radar dish on an SCR-584 alt-azimuth radar rotor. It is owned and operated by the MIT UHF Repeater Association W1XM but used for a variety of purposes including:
