Standard Horizon GX2100

I've recently installed this radio on my Westsail 32.

I like the integrated AIS/DSC - just 'point' to an AIS target, push a couple of buttons and you've made a DSC call to that target. Sweet. AIS only works if the unit is connected to an external GPS. (GPS's are so inexpensive you'd think they could incorporate one for a few bucks more)

I like the alarm modes - Alarms are available for both Closest Point of Approach (nm) and Time to CPA (min).

The display isn't bad. A bit small; but very usable.

I liked the ease of installation. I run a simple buss for my GPS output (no fancy multiplexers or gateways) and the radio seems to get along well with the other equipment on that buss.

The High Speed output would connect to an external display or chartplotter that accepts the sentences. My chartplotter won't so I left that unconnect/untested.

The fog horn feature works as expected.

The Remote mike's display is very small but, as with the one on the radio itself, very usable.

I didn't like that the display only showed the first 10-char of the target's name (m/v Sanko Mermaid shows up as "SANKO MERM"). But with the ability to "point and call" the target ship that's becomes almost moot.

I found a big range of prices from $400 at We$tMarine to $308 from a small online vendor. I went with the cheap vendor.

Overall I've very happy with the radio.

sailingdog Actually, NMEA 0183HS is not a serial bus, but just regular RS-422/232, but with a higher baud rate than the normal NMEA 0183 connection.

Uh, ya, me thinks that something is lost in translation...

Bottom line is that this can output NEMA 0183HS sentences. NEMA 0183HS is a serial bus. Also realize that this unit is an AIS RECEIVER ONLY. (Which means that you can see them, but they can't see you.)

ActiSense has a serial bus to USB gateway that you can learn about here. It will enable you to connect this radio to your laptop chartplotter.

I have no affiliation with either ActiSense or Standard Horizon... but I know that ActiSense Tech Support does venture into these forums.

I would be very interested if, and when, a manufacturer comes out with a similar radio that transmits and receives AIS data, and even more interested if it used NEMA 2000.

eherlihy Well, almost. The Garmin AIS 600 is ONLY an AIS Transponder, not a VHF.

Garmin also makes a VHF 300 AIS which is a VHF radio with an AIS receiver, similar to the Standard Horizon unit mentioned in the OP, except that it does support NEMA 2000 (and is a lot more expensive).

Garmin makes it now. The AIS 600

https://buy.garmin.com/shop/shop.do?cID=250&pID=63743

Personally, I am not interested because I only want to receive AIS information, and I want something cheap.

Standard Horizon's Tech Support can be reached at: 800-767-2450 or marinetech(at)vxstdusa(dot)com

dwoodriff So, how do you connect the GX2100 AIS output to a laptop using USB port?

Valiente I saw this at the boat show last week (I bought an HX850 handheld with the integral GPS!). It outputs to a plotter or a PC although you might have to tailor the connectors depending on USB or serial, etc. Everything Bill says is correct (as usual in the world of comms), but check with the dealer for your particular situation.

The AIS display on the radio is basic, but serviceable and gives the usual bearings, distance, speed, lat/lon and so on of the AIS transmitting vessel. I wouldn't bother outputting to a plotter in a recreational setting, but I would bother were I entering a major commercial harbour and/or at night, because I find one of the best features of AIS is the (usually) red, yellow, or green alerts that convey whether Ship X is at anchor, stopped or moving.

On the basis of avoiding "all eggs in one basket", I would consider wiring a second antenna to the rail with the PL-259 connector near to radio. That way, if the mast-top antenna fails in some manner, you haven't lost both VHF and AIS in one stroke. But that's just my belt and suspenders mentality at work.

I really like these units, and I suspect when I am ready to buy a VHF for the pilothouse in two years, it will be this or a similar model.

btrayfors The GX2100 incorporates an active switch. You only need ONE antenna...the normal VHF antenna.

The Standard Horizon GX2100 has a "38400 AIS VDM sentence output to a compatible GPS chart plotter". Should be adaptable to a laptop.

It apparently also has the facility to call a ship using its DSC directly.

Lotta stuff crammed into that little box :-)

GeorgeB No prob. Havenít seen the Standard Horizons radio that you mentioned, but Iím assuming it outputs to your NEMA bus where it is available to your chart plotter or computer. I have a DSC radio and it plot a friendís position when he transmits if you have inputted his DSC number into your own radio. Pretty cool, these (new) digital radios.
