The SC-91LT / C1 is a radar system designed to meet the requirements of the International Maritime Organization's Safety of Life at Sea (SOLAS) convention. Manufactured by Hyundai Welding Co., Ltd. (Pohang), this radar operates on both X-Band and S-Band frequencies and is approved by DNV. The system uses electromagnetic radar technology to provide reliable navigation support for maritime vessels. Common issues reported with this model include magnetron end-of-life after 5,000 to 8,000 hours of operation, bearing damage in the antenna rotation motor after 30,000 hours, display backlight failure, heading marker misalignment, and water ingress in the waveguide due to compromised pressure sealing. To ensure continuous operation, it is recommended to have a spare magnetron on board, with a lead time of 1 to 3 weeks for replacement parts. Regular maintenance includes magnetron replacement every 5,000 to 8,000 hours, annual lubrication of the antenna bearing, and a weekly performance monitor test as per IMO requirements. An annual inspection is also advised to maintain the radar's optimal performance.
