AIS Audible Alarm

[tarik]

Evening all,

Is it possible to fit an extra loud alarm 'speaker' to the laptop for the purpose of an AIS alarm? It will hopefully raise me from my slumbers when cat napping.

I can visualise extreme difficulty with 5 mins on/5 mins off .

Many thanks for all replies

If the laptop speakers alone are not loud enough you can plug in a pair of standard PC remote speakers. They will need power, of course, which will be bad news for the batteries on passage.

AFAIK there is no simple way of attaching an alarm (bell etc.) to a laptop.

AIS alarming

The Alarm has always been my least favourite part of our NASA AIS. A vessel enters within the alarm range, the alarm bleats, but you cannot silence its response to that signal and still have it ready to warn you of another vessel. The alarm sounds all the time any number of ships are in the alarm range unless you turn it off altogether, when you have to remember to reset it once traffic has left the area.

Well, if you're going for serious offshore then something like the nasa reciever might be a better/additional option. It's alarm wakes me up and draws b#gger all power, a laptop on all the time eats away at the batts and I'd feel a bit nervous having such a crucial bit of offshore singlehanded kit reliant on a laptop.

I've got both

And radar.


5 on/ 5 off? Not a hope.

Yep, I've had the same. Worst when you're being overtaken by someone slow on a course close to yours a few miles off the beam. Solo, you're awake until it's past. But then the radar is going BEEEEEP as well so no way out.
