Update (2/9/17): The Wildwood transmitter is back on the air after a presumed lightning strike affected transmissions. The transmitter stopped broadcasting at 5:35 a.m. EST on Feb. 9. Testing took place 5:35 a.m. to 8:19 EST, after which it came back on the air, reports Steve Bartlett, vice president of operations for UrsaNav Inc. The transmitter will be taken off the air tomorrow morning (Feb. 10) so that engineers can assess and repair any damage. The Wildwood, New Jersey, eLoran transmitter will be continuously broadcasting from 9 a.m. EST on Feb. 6 through 12 p.m. EST on March 31, announced Steve Bartlett, vice president of operations for UrsaNav Inc. “Wildwood will be broadcasting as 8970 Master and Secondary most of the time, but occasionally may operate at other rates,” Barlett said. The Loran Data Channel (LDC) will be undergoing testing and may be unavailable or unreliable for short periods of time Feb. 6-10, he said.
