A network outage Monday night left the Coast Guard’s emergency VHF radio channel unreliable in much of Southeast Alaska.
Coast Guard Commander Lyle Kessler said sailors calling on Channel 16 may have difficulty reaching the watchers. This is because the VHF repeaters in the area are either inoperative or unreliable due to a network failure in a band from Yakutat to south of Ketchikan.
The Coast Guard operates a VHF repeater system that relays radio broadcasts through the narrow inlets of Southeast Alaska and around the high peaks.
“If the tower is down and you try to call us [Channel] 16, the tower is not sending the message back to us, ”Commander Lyle Kessler, Coast Guard spokesman in Juneau, told CoastAlaska.
Several VHF repeaters have been down for over a year. But the situation had improved after hiring a new contractor to maintain the system.
But a new problem with AT & T’s microwave network developed this week. Kessler said even working VHF towers only broadcast intermittently.
“They’ll go down a few seconds to a few minutes and then come back up,” Kessler said. “And then we also have the towers that were for a while due to the previous issues. “
The Coast Guard advises mariners to have another way to send distress calls. This ranges from an emergency position indicating radio beacon, a satellite phone or even a conventional cell phone.
On Wednesday, Kessler said nine VHF repeaters – Althorp, Cape Fanshaw, Duke, Gravina, Mt. Robert Barron, Mud Bay, Mt. Ripinski, Yakutat and Zarembo – were only working intermittently due to the microphone interference issue. waves.
The VHF towers on Deception Hills, Mt. McArthur and Duffield are already out of order and awaiting parts from the contractor. A VHF tower on Sukkwan Island is also not transmitting, and bad weather prevented contractors from investigating the cause.
Those on the water are urged to watch channel 16 and relay any unanswered calls for help to the Coast Guard. The number of the Juneau sector command center is 907-463-2980.
