AIS = The Automatic Identification System is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS).
AIS operates principally on two dedicated frequencies or VHF channels:

AIS 1: 161.975 MHz- Channel 87B (Simplex, for the ship to ship)
AIS 2: 162.025 MHz- Channel 88B (Duplex, for the ship to shore)

There is also AIS Long Range that uses short messages so theoreticaly the range can be higher.This is currently used much less.

channels (LR):

AIS 3: 156.775 MHz- Channel 75
AIS 4: 156.825 MHz- Channel 76

AIS detected by my local station click here. Another station in the area is PE0F click here.

Software used at my side is now the 2 channel (with AIS long range support) AIS Catcher from Jasper.

Antennas used:
The LOG (Loop On Ground) antenne really works well try it if you can fit it in your garden. Great RX antenna.
A bit more on LOG you can find here also. Receive examples to listen to : Click here.

Preamp used: (from another antenna system called Flag/Pennant LOOP)

Some video's on LOG
Video 1 loop on ground build.
Video 2 loop on ground compare.
Video 3 loop much bigger test.
Video 4 loop with preamp.

Convert a LOG antenna to a LIG (Loop In Ground) just put it about 2 cm under the soil :)
