Up and down vessel number.
- hello all,
i'm a new user from few weeks in AIS reception, and have e lot of fun with it.
But i'm suprise by the number of vessel receive in my location.
this number periodicly up and down but i dont know why .
here is my statitics : http://www.aishub.net/aisGraph.html?rrdname=2338&sname=Brest
Is it a normal phenomem with AIS signal (periodic transmission from vessel)
or is it a problem on my side from ais decoder or hardware ?
- receiver(RTl dongle + antenna log peiodic vertical polar)
- audio link to AISMON (mixer in<->out also using vac)
- UDP link to AISDISPATCHER
