i cannot possibly anderstand what ais have to do with aprs, and why isn't it possible to remove it whithout influence on aprs stations? could you please make the ais data default to be hidden, and those who like it could the turn it on.

Ah. I can understand it easily! It's position information from moving
vehicles transmitted over radio. It fits in here quite naturally, and
especially the folks who do Search-And-Rescue work with boats having
either AIS or APRS transmitters on board can benefit from the combined
view. APRS transmitters are much cheaper than AIS transmitters for the
small rescue vessels of volunteer SAR groups. There are also pleasure
boats with APRS transmitters on board, owned by hams, and it's useful to
see them on the same map with the bigger boats having AIS.

I've had very good feedback from some SAR folks around the world about
this.

But it is possible! Just tune your filters to hide AIS, and then make the
tuned filter list *your* default filter using Preferences => Save current
map view as default view. Here's a short video showing how to tune the
filters:

Sorry, but no. A large amount of users would then come asking where all
the AIS ships disappeared suddenly. I also prefer to show everything by
default so that people can learn what data is available - they can then
limit the data set using the filters as they wish.

It's "aprs" as you can see whats hapening around you. The only thing i don't like with the AIS on aprs.fi is that the filter now doesnt allow to remove the traillines from AIS and keep them on regular aprs traffic.

And if it was up to me even airplanes would increase the usage of aprs.fi

If people don't bother to make their own default filter then maybe aprs.fi is not the place to be :-)

You can also argue that weather stations / sattelites etc has nothing to do with aprs but it does. Just filter out the information you don't want to see.

So it all depends on what YOU want to see or not.

Tnx for the good answers, and of course i couldnt agree more abt setting default filter, bu i'm not able to save the filter as Default !! if i was so i would be a happy camper.
