Thought about that.. I really don't want the expense or additional complications. Goal is to at least start out with a "clean" network. I can dirty it up later

Thanks, though...

Still sulking....

They made a software mod on the 2150 model to allow all data to operate at the same speed, which is good.

So I have to decide between AIS or DSC, which is disappointing.

the 2200 seems to be a better way to go, since the GPS is integral, and you only need one data connection.

So

I wish they would support NMEA 2000.. I would rather only have one network on my boat.

I expressed my frustration to a Standard Horizon rep at the boat show. He wasn't particularly sympathetic. He did think that they would eventually support NEMA 2000


My choices seem to me to be:

1) Just hookup one data connection to my chart plotter. No DSC
2) Sell my radio, and get a 2200
3) Get a dedicated transponder... (Maybe I really should be transmitting anyhow
4) Continue to sulk about this

It seems those on the far side of the ocean can't agree on anything.

Anyway, my point being, Fuzzy 'ol pal, that if one were to import one from the States it should work here just fine...
Actually there are a couple of reasons:
1. The US Band Plan was established before there was much in the way of world cruising. It didn't work (as pointed out for Canada) so the rest of the world went its own way.
2. The difficulty to change a band plan is pretty severe. When LORAN was shut down in the US several of the stations had to run for a couple of years to fulfill treaty obligations with Canada.
3. Even for old guys like me it is hard to remember how much both the technology and the usage has changed. The duplex US channels were used by marine operators - I don't think there is a VHF marine operator left in the United States. So the channels go unused as there is no driving force (and of course the regulators don't have a clue - that is why they are regulators) to change them. LOL

Fair winds and following seas.

Re: AIS integrated into VHF Radio.

Cool.. thanks! I may still need to sulk some more... Anybody want a deal on a 2100?

All the VHF i listed in my post support NMEA 2000 http://www.sailnet.com/forums/1461722-post7.html

I have an em-trak AIS B transponder - it can send AIS data on NMEA 0183 (high speed AIS need high speed NMEA 0183 port) and NMEA 2000 at the same time, solve the problem with older equipment.

Re: AIS integrated into VHF Radio.

Hey,

The radio has a small 'radar' like display.

To the best of my knowledge there are a few radios that integrate AIS receivers:
Standard Horizon GX2150 / GX2200. These use NMEA 0181 to interface with other devices like chart plotters. The GX200 has a built in GPS while the 2150 gets GPS info from the network. These radios support a second corded mic.

Navico (Lowrance LINC 8, Simrad RS35). These radios use NMEA 2000 so connectivity should be plug and play. The RS35 can use the HS35 wireless remote.

ICom 506 (not available in US yet). This is another unit that uses NMEA 2000 for connectivity.

I have the SH 2150 on my current boat. It works well and I send the AIS data to a PC running seaclear that can display the AIS information. The remote mic is in the cockpit so that at night I can determine how close the ferry will get to me, and when I need to change course to stay out of the way.

Re: AIS integrated into VHF Radio.

There are lots of VHF sets with integrated AIS receivers

Lowrance (Navico) Link-8 DSC/ VHF Marine Radio - LOWRANCE | Marine Electronics
Simrad (Navico) RS35 VHF/AIS Radio - Simrad Marine Electronics

Icom IC-M506 VHF Marine Transceiver - Features - Icom America

All of these have AIS plot on the display


Most need GPS input - but that's no problem?

Some of these models must be available in Australia
LOWRANCE LINK-8 DSC VHF AIS ? WATERPROOF ? AUSTRALIAN MODEL | Island Inflatables

The railways.. that makes sense. Thanks!

Spectrum planning issues occur everywhere (blimey, we've had to deal with our fair share and there's nothing quite like a bit of channel interference to help people make the shift*) but I guess some countries have more desire to do something about it than others. I don't imagine it would be too difficult to simply tell everyone they need to switch to 'International' after a certain date.. but then given the bureaucracy, time and costs involved - nah, it's not going to happen.

* = Over here, the spectrum for wireless microphones (the type used at concerts and conferences) has changed twice in the past 20 years or so and is changing again right now. On the verge of one change, we had been demonstrating a new system in a local church which happened to have a gymnasium next door. The preacher couldn't see the need to spend the $$$ until, suddenly, right at a key point in the middle of his sermon, a high-pitched female voice broke in loud and clear over the speakers saying "C'mon girls! Lift those legs!!!". We got the order for new mics the very next day.

I teach the Restricted Operator's Certificate (Maritime) course for our local squadron, and even I find that the matrix of channels/areas/users/authorized-uses is, well, convoluted to say the least.

On topic, I have a SH GX2150 (with AIS, without GPS) hooked up to both ship's GPS (to radio) and chartplotter (from radio) and am very happy with it. The radio *and* its remote mic both have a simple and easily readable display of nearby AIS targets with vectors, and you can call up additional detail on any, as well as call them directly by MMSI. The display is small but uncluttered, to the point where it's often easier to see than the targets on the chartplotter hidden amongst all the other info.
