What Is A "Relay" Distress Alert On MY VHF DSC?

Sitting in my slip in Long Beach, CA, today my VHF DSC alarm went off with the message "Relay", some coordinates and the time. I looked up the coordinates and they were near Mag. Bay, Baja, Mexico. I know what DSC is about but I am not familiar the "Relay" portion of the message. What does this mean and what should one do upon receiving such a message?

Thanks!

Yep, it's very important that you do.

Someone I knew passed one on three times and a week later he won 3 million dollars in a lottery.

Someone else I knew didn't pass one on and two years later his dog died.

Re: What Is A "Relay" Distress Alert On MY VHF DSC?

Thanks all. Good Info. Here in Los Angeles/Long Beach Harbors when a DSC alarm is sent hundreds vessels alarms go off. From time to time there are recreational boat DSC alarms generated from boats in their slips. These alarms create a bit of chatter on CH 16. But today, with the "Relay" alarm, there was zero chatter. Nothing mentioned on Ch 16 by the Coast Guard or any other entity. Just curious. Thanks for the Info.

Re: What Is A "Relay" Distress Alert On MY VHF DSC?

Normal recreational DSC controller can not handle the Mayday Relay call.
So you received a DSC Relay alert from a coast station or SOLAS vessel.
These are required to usa a Class A DSC controiller.

The procedure at
DSC Distress
explains:

The DSC distress relay alert is transmitted as follows:

tune the transmitter to the DSC distress channel (2187.5 kHz on MF, channel 70 on VHF),
select the distress relay call format on the DSC equipment, key in or select on the DSC equipment keyboard:
All Ships Call or the 9-digit identity of the appropriate coast station,
the 9-digit identity of the ship in distress, if known, <<<<<<<<<< only DSC Controller Calss A
the nature of distress,
Wilhelm

Re: What Is A "Relay" Distress Alert On MY VHF DSC?

And there is a term "mayday relay" for the ship station who hears a mayday and is the communicator in the middle. Ie distress vessel calls Mayday, Next vessel provides Mayday Relay by contacting Rescue Org.

To make it easy. If the Mayday Vessel was 40 miles from shore, on VHF, and couldnt reach the Coast Guard or Safety org, a vessel at say 20 miles would provide the Mayday Relay.

I am not in the USA, but here (OZ) you need a licence to operate a VHF and one should have done the appropriate course. Is that not the case in the USA?

And that applies to EVERYTHING, not just radios.

Re: What Is A "Relay" Distress Alert On MY VHF DSC?

An important issues is that some radios have a dsc mayday relay function. This should NOT be used as per recent ITU. Recommendations. The feature is being removed from radios. The relay should be done by a normal dscroutine call to the nearest coastguard staton within range and followed up by a mayday relay call, using the pro word MAYDAY RELAY.

In general just relay a received dsc mayday by voice only , this removes the risk of multiple dsc distress alters that have to acknowledged by the coast guard station

This is doubly the case in MF and MF operation, in that case always just use voice relay or a dsc routine call
