It is not a warning - it is a NOAA weather forecast. If it is interesting to you here is a URL that will provide a lot more about NAVYEX Wx. NAVTEX Product Listing
Also there is a lot more on NAVTEX than Wx. Before you spend money to solve the problem you describe in your initial post, be sure to thoroughly research NAVTEX.

|sailingdog||XM/Sirius is only good if you're sticking around North America... Their coverage in the rest of the world is non-existent for the most part.|

|Quickstep192||Just a thought....... Is XM/Sirius and option here? A friend has it for his chartplotter and overlays the weather right on the chartplotter.|

While the Yachtboy could conceivably do the job for you, I've found that any transceiver built in the past 20 years or so has a much better receiver and is far easier to use.
If you do decide to go the used transceiver route, let me know (PM me) and I may be able to help.

Thank you all for your valuable info. I have thought about getting an AIS transponder to see and to be seen and I have a little GRUNDIG Yachtboy. I am not sure about the NavTex, it says it will transmit warnings. I am after the regular marine weather forecast. A nice 20 kt+ wind will not create a warning but would be nasty riding the Gulf stream while the Wind comes from the North!
Special thanks to Bill (btrayfors) this was a primer on SSB on Island Packets. This is really appreciated and comes very handy during this economic times. I assume, I don't need the ground (rub rail) for receiving just the hoisted wire antenna ... This will be my way to go. Thanks again!

Get an AIS receiver, ID ships passing within VHF range and ask them nicely for weather info.
This is actually a marginal idea at best and I would myself take btrayfors' sound advice, but I'm just throwing this in there as a possibility.

2nd the NAVTEX reccomendation
I have been using Furuno NAVTEX for years. For the type of sail that you describe, it will work very well, very reliably, at an affordable price (<$300). The NAVTEX spec is 250-nm offshore, but 450-nm is very common reception.
A down loadable pdf of the product brochure is on the following URL:

For that trip, I recommend you do one of the following:
1. (Cheapest) - buy a decent, low-cost portable receiver which will receive SSB signals. The DEGEN brand models run less than $100 and have received very favorable reports. They're everywhere...check out eBay listings.
2. (Smartest?) - buy a used marine or ham transceiver for under $500, and install it so that you can receive well.
Notice that I did NOT include buying a good SSB receiver. That's because for the same money you can get a TRANSCEIVER which can later serve your transmitting needs as well as receiving. All modern transceivers have excellent receivers built-in. NO need for a separate SSB receiver, IMHO.
For a receiving antenna, you can just use a length of insulated wire, hoisted with a spare halyard.
Later, when you add an automatic tuner (about a $400-500 expenditure), you can set up for transmitting as well. For the 'alternate backstay antenna' just use a length of insulated 3/16" s/s lifeline about 40' long and put small loops in each end. Hoist one end with a spare halyard. Tie the lower end off to the pushpit on either side of the boat, using a couple feet of 3/8" or 1/2" poly line. Then, run a length of GTO-15 insulated wire from the lower end of the antenna belowdecks to the tuner antenna lug. Locate the tuner underdecks as close to the bottom of the antenna as you reasonably can.
By the way, RF grounds in IP's are pretty easy. The ones I've seen and done all have a s/s rub rail all around. All you need do is link them together electrically (usually there are 4-5 pieces overall), and use them for an RF ground or counterpoise. They work like gangbusters.
Just run a ground strap from the antenna tuner ground lug to the rub rail, using a bolt which passes thru the rail, thru the hull, and attaches to the groundstrap inside the hull. Then, run a ground strap from the antenna tuner's ground lug to the nearest bronze thru-hull which is not otherwise connected to the boat's bonding system.
Pretty easy installation. If you have time, and $$$ for the tuner before your trip, you could have an excellent SSB installation.
For WX, listen to USCG broadcasts several times a day on published 4, 6, 8, 12 mHz frequencies. These are also re-broadcast by WLO in New Orleans, and several ham nets (e.g., the WaterWay Net on 7268 LSB every morning at 0745EDT and the MM net on 14300 USB periodically during the day).

Receiving weather reports 150 miles offshore
Usually I do coastal cruising in the Gulf but I need to relocate my boat to the Chesapeake. If weather allows it I intend to jump from Stuart Florida directly to Beaufort,NC, a 480 mile leg riding the Gulf stream. No SSB on board and VHF nor cell phone would work while I will be about 150 miles off the coast.
What would be a good recommendation for a receiver to get reliable weather information without breaking the bank. I will install SSB eventually but don't want to go through the expense and time right now.
Thanks for any input.
