Just think about it. When your VHF
picks up a DSC
call, what happens? Ours will whine like crazy and I have hell of a time to mute it (say if my crew are asleep).
A DSC MOB
device works exactly along the same lines: a distress
DSC call is put up on air: all DSC VHFs should/will light up red, pick up the data and store it for your reference: call nature, position, caller id, etc. Many will let you navigate to the caller with one press of a button (ours does).
And your plotter will display the MOB. Off course, only if you have it wired with your radio
, which is not what all boat owners do.
I have seen a test of DSC AIS
MOB device and it lit up all alarms (DSC on the radio
, DSC on the plotter, AIS
on the AIS unit). Maybe this technology is not allowed in the US. I know they have their own regulatory bodies out there.
