...KOHX Doppler Radar Out of Service for Maintenance This Week... Beginning today, July 7, the KOHX Doppler Radar will be down through July 14 for the replacement of the generator, fuel tanks, and accompanying components. The radar may return to service earlier if the maintenance is completed ahead of schedule. This activity is important to support the radars operation during periods of commercial power outages, specifically when hazardous weather is present. This generator update is the fifth major project of the NEXRAD Service Life Extension Program (SLEP), a series of upgrades and replacements that will keep our nations radars viable into the 2030s. The first project was the installation of the new signal processor and the second project was the transmitter refurbishment. The two remaining projects are the refurbishment of the pedestal and equipment shelters. The Service Life Extension Program will complete in 2023. During the outage, radar data from Hytop, AL (HTX), Fort Campbell, KY (KHPX), and the Nashville Airport Terminal Doppler Radar (TBNA) may be used for Middle Tennessee.
