Now that all new VHF radios have the GPS input, it seems that there
should be a little GPS box the just puts out the NMEA signal with no
other functions. You could then use the output from your main GPS for
something else and have the radio’s readout for a position back up.

Come to think of it, do those little GPS units sold to plug into
laptop computers for street maps speak NMEA?

I have an old aviation Garmin GPS 90 that has the same plug as my
GPSMAP 76. It outputs:

NMEA 0180 and 0182

0183 Version 1.5

Approved sentences:

GPBWC, GPGLL, GPRMB, GPRMC, GPXTE, GPVTE, GPWPL

NMEA 0183 Version 2.0

Approved sentences:

GPGGA, GPGLL, GPGSA, GPGSV, GPRMB, GPRMC, GPRTE, GPWPL

Can anyone tell me if this would work with the DSC radio? Spending its
retirement inputting position to the VHF might be a good use for this
box. I could then take my 76 back to the helm without losing the DSC
connection. Besides, if I want to know the location of the nearest
airport, I’ll be all set

The GPRMB, GPRMC, and GPGLL all have current Lat-Long information
imbedded in them and should be acceptable for any DSC Input.
You would want to use the Version 1.5 if you also used it to feed
your Autopilot as it includes the GPXTE sentance that the autopilot
uses.

I just made a quick stop at West Marine during my son's guitar lesson
and it appears I was led astray the first time I looked at the new
radios. None of them (according to the story this time) show the Lat
Long on their display so a GPS receiver without a display wouldn't be
a back up except for the distress signal.

The salesman also told me that the USCG is not currently receiving
position information on the channel 70 calls, at least in the
Northeast. Does anyone know the status of the Coast Guard system? I
don't see much point in buying one of these until they are with the
program.

Wrong radios. The Icom M602 VHF and M802 HF both display lat/long
continuously. I believe the cheaper M502 does, also.

I wouldn't suspect the West Marine/Uniden cheap crap to display anything
but the channel you're on.

I'm not sure if anyone here gets the position info from the Ch 70 stuff
but my Icom radio does have the position on the screen. My GPS has a
junction box that allows me to send info to several things at one. My
in particular feeds VHF, HF radios and a laptop charting system.

Yes, there are "black box" GPS receiver/antenna units, but they cost
as much as a low-end handheld GPS.

A single NMEA output should be able to feed at least four listeners.
I have one GPS feeding an autopilot, computer, DSC radio and radar
simultaneously, and am about to add a Bluetooth module to the mix, to
get the NMEA data into my Dell PDA, for use at the upper helm.

The current NMEA wiring diagram for my boat is on my GPS/NMEA site...

I have a black box GPS that plugs into a laptop and uses the laptop as
the power source. Something like that for the VHF might be neat. If
you just plug in a handheld you'd be buying batteries regularily.

Here are some links:

Selective Calling (DSC) distress calls on Channel 70 until 2006..."

The USCG is way behind the rest of the world in DSC Technology, and
the US deployment of a full Shoreside DSC is years behind scheduale
due to Congress's lack of funding, for IMO Treaty Compliance. USCG
has a few "Test sites" on the East Coast and Gulf Coast, but total
deplyment is still years away, especially up here in District 17.

Roger,
Whoever you talked to at WM was not very well informed on the products
he was selling. All the radio's I looked at had Lat-Long display
including the Icom and the WM 500 which is a WM brand marked Icom.
