From the site's 'maps' page, I clicked through to this map:
http://www.aisliverpool.org.uk/currentmap.php?map=33
but at the time of posting, there are no ships shown on it. Is that
because there are no ships there at the moment, or because the site is
(obviously) Liverpool oriented, and this map is outside the area they
want to cover?




I'm assuming he has a very high receiving antenna on a big tower near
Liverpool that can receive data from as far away as Ireland as I see
targets from over on that side. Maybe he has multiple receivers around the
Irish Sea linked to it, but I'm not sure.

I'd bet, watching the coverage for quite a while, now, there are no ships
broadcasting AIS from where you want to look. The coverage, the linked
realtime pictures taken when the AIS target passes in front of his
recording camera equipment stored on the website....it's the best AIS
coverage on the planet...even much better than the subscription ripoff
artists which only give limited coverage.

What a great donation he is making to the marine community, worldwide.

I have e-mailed a sailing friend who lives near Liverpool (a Liverpudlian!)
to see if he is aware of the site and if so can he describe the receiver(s)
and their height etc.

He should contact the webmaster(s) and get a tour, or at least tell thim
how much we all appreciate the free access. This site has got to cost
quite a bit of money that must come from somewhere.
