15 May 2014 22:17266463Sorry Heike but all I got was a green blur even though I zoomed the picture, good idea though.-----------------------------------------------------------------------
I try to be neutral and polite but it is hard and getting even more difficult at times.
------------------------------------------------------------------- - 15 May 2014 22:29266464the second one is clearer. as taken a shot from the computer it wont be any better unless its less activity on the channel.
I was thinking of the distance as there is a brilliant reception tonight. It does not happen very often...
Distance is 169 nautical miles which is far beyond the horizon.

I've had it for a long time. You can subscribe to it but it's free. Also there is a brilliant website here where you can see live webcams from the bridge of many of the liners that come into Dover.
http://www.kroooz-cams.com/ Just click on the ship in port and provided its on the list you can see them.
Maybe this should be on the sea news forum? I believe Paul has mentioned Marine traffic on there anyway.
Hope this helps.There's always a little truth behind every "Just kidding", a little emotion behind every "I don't care" and a little pain behind every "I'm ok". - 16 May 2014 13:49266492thanks for info Jacqui, just looked in at the marine traffic one, very addictive like our channel traffic one on a massive scale.

Flight radar 24...there is a windows 8.1 app for this too.

"Channel Traffic" and MarineTraffic are one and the same. If you look at the blue bar at the bottom of the Channel Traffic screen you can see that it is a link to the local area from the MarineTraffic site .
MarineTraffic is global and seems to be the most popular of the numerous websites which have sprung up since the introduction of AIS on shipping in recent years.
These involve a host of dedicated amateurs who obtain their own AIS receiver and feed the output to the websites concerned.
Coverage is limited to those coastal areas where the amateurs are situated and the VHF range from their location, typically a minimum of 20 nautical miles, much further if they have a aerial which is high up and unobstructed.
The AIS system works via transponders on each vessel which communicate with each other and maritime shore stations on dedicated VHF channels via time division multiplex with each transponder transmitting in its own time slot.
It is very useful to us at sea as we can see full details of vessels in the vicinity to enable identification of the anonymous targets displayed on the radar screens. It also enables a lot of information to be transmitted automatically without the need to communicate it verbally to coastguard stations when entering traffic areas which they are monitoring, this indeed being the main reason it was set up in the first place.
