Equipment Downtime

Failures and Spares w Most failures are user or ship related w Power outage, antenna repoints, gyro failure, unfamiliarity with gear, etc. w Solution: Learn to work with gear and ship quirks w Antenna pointing failures occur, but usually are not catastrophic w Solution: Work with Sea. Tel and learn to work with gear/ship quirks w When equipment dies, it is usually RF gear, despite it being the “most reliable in the business” w Solution: Spare LNAs, depot converter and power amp spares in SD
