Hey Larry you might be interested in Jacks links www.ganssle.com


Thanks, I'll take a look.

Anyone noticing or knowing about AIS fixed obstructions/bouys/etc. being
transmitted from shore stations in their area, please let us all know what
you know...thanks, too!

"AIS (Automatic Identification System)

The International Maritime Organization has ruled that all vessels of
300 gross tons or greater and all passenger vessels must carry AIS
transponders. These transponders broadcast their own AIS data and
receive it from other vessels. Information such as the vessel
identity (MMSI, vessel name and callsign), position, rate of turn,
course, speed, destination, and cargo is continuously broadcast over
VHF frequencies and displayed on dedicated or integrated navigation
systems. Though these active systems are expensive, there are low
cost, receive only units available that provide, for the small boat
owner, a display of much greater use than radar for these 'big boys'."

===========================================

The biggest issue for small boats is not seeing the big guys (they
show up easily on RADAR), but being seen. Only an active AIS
transponder can provide that assurance since small boats are easily
overlooked or missed entirely on a large ship's RADAR. As large ships
come to rely more on AIS, and devote more time to monitoring, this
will become even more of a critical issue.

Hi all

I do now want to get "started" with passive receiver for testing.

Have you an adress/link to a "starter" kit? (hopefully below 3-400USD)
