The current reception range of my AIS receiver

Here is a screenshot of the range of ships my raspberryPi powered AIS receiver gets right now. From Rotterdam in the south to far above the West Friesian Islands in the north. Few bigger ships in the IJsselmeer are received also.

Amsterdam, IJmuiden harbour, the North Sea Canal and the IJmuiden approach zone are fully covered.

The screenshot is from my stations statistic page at fleetmon.com, my favorite ship tracking site. You need a free account to access Fleetmon.
