DSC VHF - Query

Mike B · 13 April 2004, 16:24

I've been trying to find this info in various places on the web but have not suceeded can any of you guys help.

When a DSC enabled VHF receives a distress call or distress acknowledgement does it plot the position on a connected GPS / plotter ? If so is this a standard feature or only availble on certain models?

I have seen various mentions about "position polling" to enable you to request the position of a vessal but again I can't work out whether this just comes back on the VHF or is transfered to the GPS / Plotter ?

I'm looking at the following radio's and think I have settled on the Navman any comments from anyone ?

XM DSC/VHF
Nasa SX35
Silva S10
Navman 7100

Many thanks

Mike

To enable the VHF DSC to plot the position on the chart plotter it would need to have an NMEA output. As far as I am aware vhf dsc's only have an nmea input FROM the GPS/Plotter.
However, the combined VHF/DSC/GPS unit from Silva may well have an output to a plotter so maybe it would place the distress alert as a waypoint.

Don't forget the Icom models!!!
they work well, & have fantastic after sales support.

But an Icom DSC costs 3 times as much as any of the models listed above.

Im having a Silva S10.

I must confess I use an Icom M601, M401 and 2 * M1 euro v's, 1st class kit.

I agree, you cant beat icom. But i can't afford £600+

I know the later Navman stuff is nmea but read my posts here

My judgement is still out on Silva, My S15 only lasted three months before dying. They are reoplacing it under warranty but if it goes again I am looking for a refund and buy a radio I can rely on.

The Icom 601 will do it.

Will it? Great. So when the Ribcraft finally arrives as the M601 will be connected to a Garmin 188C it should work both ways?

Has some good, albeit very basic info videos on how DSC is used
both ways.
Request position and get in on your plotter from the VHF
as well as the emergency functionality.
Good simple demos for those not in the deep know.

Thanks guys

Only query now is would both boats need an M601 or can the M601 get the position from any other DSC ?

Although at more than twice the price of the cheaper alternatives not sure if I can justify it. I'm sure its quality kit though.

Poor David.
Thats only the 16th time you have mentioned your (non) boat delivery.
I really feel for you.
You ordered on the 14th October that was in 2003? I take it?
Those Ribcraft chaps must hand build each rib with such loving care that it takes a long time to make each one. And then, when built, they are so good, that this huge queue of buyers form, who push the waiting list way out.
Still it will be wonderful when it arrives I am sure.
Will I see the rockets and other fireworks go off across the Bay when it turns up?

Rockets and fire works? The Queen is lauching her!!!! and the Red arrows have agreed to come!
OK I will shut up about it now. I will sulk in silence Brian.
