I have installed an AIS receiver in our vessel with which we travel
Long Island sound NY. So far I have never seen an AIS contact, I am
beginning to wonder if the unit even works. It is a millitech SR161.
Has anyone seen a contact in this area?

I have not yet tried to get an AIS receiver working but virtually all
commercial shipping is transmitting AIS info these days, and there is
a *lot* of commercial shipping on Long Island Sound - tankers, tugs,
freighters, etc.

If you are within visual sight, you should be receiving a signal if
everything is OK.

That is what I thought but it turns out very little of it is used
here. I know for a fact the tugs / barges don't use it which annoys
me to all get out since that is why I got it. There may be some
shipping using it in the Newport area shipping channel, but I haven't
gotten that far yet to try.

The statement that "tugs / barges don't use it" isn't true. I've seen
quite a few tugs that do have AIS transponders. They may not be required
to use it, but some do.
