Default AIS recommendations?

I live in an area not covered by online AIS, and am wondering what the best options might be for receiving local signals myself. Was looking at some iPad apps, but couldn't be sure about what I was seeing. Would love to be able to plot the stuff on a map, but would be happy just to receive the datal

Would like to know what works well for those of you who use it. Am thinking I could use the IF-out option in the BC436 or the PSR800 for the radio end.

ps - also a related question. Does anyone feel like there's a reduction of traffic on Ch-13 as a result of AIS?

you could try a cheap ($15) SDR radio. i tried it and it worked here, but i'm too far inland to receive much traffic.

Some USB AIS receivers on this page.
The Comar SLR-350N Network AIS Receiver has USB port on it and works great uploading AIS data to AIS tracking site.

Suggestions all appreciated, but are very high-dollar. I live in Richmond, VA which is very limited as a port and am too far from the river to be an effective AIS contributor--not likely to attract the grant of a free receiver from MarineTraffic...whose iPad app I'm currently using. Have been unable to make the RTL dongle work, but still like it (or the AIS dongle) as a possible solution if I can overcome the computer issues.

Am more interested in interfacing the signal from the IF of a scanner (I have several with the appropriate capability) with an iPad or even my PC if necessary. It would be a mobile solution as I try to get a feel for what goes on. (There is an AIS site in Hopewell, VA about 20 miles away, and vessels disappear just a few miles upstream as the river begins to bend and twist.

The first to-do, before you try to decode: are you positive you can even receive the signal? Can you hear it, or, can you see it using your RTL dongle?
