"Smart Radio SR161, SR1612 and SR162G AIS Receivers

The Smart Radio SR161 and SR162 AIS Receivers are compact, easy to
install, stand alone marine receivers that monitor the channels
assigned to the Automatic Identification System or AIS. These radio
receivers are specially built for marine environments for the intended
use of deciphering Automatic Identification System data."

Actually, the SR161 is a Chinese product (http://smartradio.ebigchina.com/),
and Milltech Marine is a U.S.A. distributor. I have purchased the SR161
from Milltech, and am very pleased with it. As far as performance and
features, it seems to holds it's own against the Nasa AIS Engine, which I
also have.
