last "ditch" VHF
hi again folks,
i'm curious what VHF you would suggest for emergencies, the one you're going to be listening in on when your floating in the middle of the ocean next to your EPIRB after tragedy has struck. i'm thinking of a radio that you keep with you at all times when on deck, the one that never leaves your side. |

The fade today for coastal navigation is the DSC (Digital Selective
Calling). This new breed of VHF is connected to a GPS and has a distinctive signature. In order to make use of this DSC you have to register it with the coast guard. They logged in your signature, call sign, boat description, navigational equipment, emergency and survival gears. Then the information is programmed into their data bank. As I witnessed, when you call the coast guard, traffic and other vessel with the proper equipment the name of your boat with its position appears on the their computer/digital radar system. This way when your are in distress and use your DSC they know your GPS position, the name of your boat and monitor your position. When you are outside of the coast guard radio range some people are using sat/phone and EPIRB. Last week a 36 foot sailboat was rescued by the US guard at approx 200 NM from the coast of Nantucket.

I have a Standard Horizon HS460S handheld VHF. I attach it to my PFD with a lanyard so it's always with me. (if not wearing PFD, I attach the lanyard snap clip to a 'D' ring on my vest) You do realize your transmission distance is around 5 miles, although you may hear messages from farther away. |

It's ARGOS. I use it and in essence you're correct but what the satellites see is a function of the transmitter. Basically you can send a data packet, what's in that data packet is up to you. We have some ocea buoys with GPS and other instrments attached. You can triangulate a transmitter location from the sat passes but the accuracy is in the 1.5 nautical mile range, not the sub 50m range with GPS.

It uses satellites to receives signal from the Argo buoys locate on vessels and then shows the position on a digital computer screen. This way they can track down the position of the racing sailboats at all time and advise of alternative route to avoid hurricane and storms or just giving updates on the race. This Argo system is not public and requires permission to use. Today, if you're looking for audio entrainment while awaiting rescue or just sailing the new Sat/radio could be a good thing to have on board.

I'm not sure you need to be talking to people while you're floating next to your EPIRB! You want to be rescued. If the EPIRB is working, they will know where you are. If it is dark, you might wish you had a flare to help them. But what are you going to tell them on the VHF? You can't just say you're 20 yards south of a used car lot or something. And what would you listen to? The weather? Save the VHF and bring some water and food instead! Others will see this situation differently, I'm sure. Good luck. Chuck |

Thanks for the correction Peter.
You're right it should have spelled Argos instead of Argo. The 1.5 nautical mile range accuracy is not all that bad when you are at sea. However for coastal navigation when you are crossing shipping lanes in the Bay of Fundy when the fog gets very thick it is not too good. Here the coast guards are using DGPS on the coast. I do not know how far the land correction bases can send their signals to validate and correct a GPS position? The same thing would apply to the WAAS. My old Loran is still functioning well and when need it I use it to validate my GPS position or back up. "Peter" wrote in message oups.com... It's ARGOS.

I bought the cheapos from west marine 2 for $70 I think they made by cobra.
I replaced the rechagables with alkaline batts and put em in their watterproof cover and every PFD has one now. I figuer that the MOB in the water will have a good view of where the boat is but those on the boat may not see the MOB. These radios have very good distance and are clear. The speakers are not great, you have to keep the volume way down or they distort. - Allen "purple_stars" wrote in message ups.com... hi again folks, i'm curious what VHF you would suggest for emergencies, the one you're going to be listening in on when your floating in the middle of the ocean next to your EPIRB after tragedy has struck. i'm thinking of a radio that you keep with you at all times when on deck, the one that never leaves your side. |

Chuck hi chuck, i just thought it was normal to have a vhf when you were in the water in an emergency. that way the rescuers could talk to you, or maybe if you see their helicopter you can let them know that you see them, or their boat, etc. i don't yell very loud! lol. it just seemed like a good idea to be able to talk to them. |

The first thing the CG does when getting an EPIRB signal is try to raise you on the VHF, getting an answer will speed rescue. Hopefully you will still be on the big boat with working VHF, but if not, a waterproof handheld would be nice. Recent scuttlebutt has noted some "Waterproof" VHFs survive immersion, but their battery packs do not.
