1. Log in first
2. Tap the filter (funnel) button on the right side of the map, enable the
"Station class: AIS" filter, tap the red arrow down to move it to the "and
not these" side. AIS stations disappear from view.
3. Tap "Save as new list", enter a nice name for your custom filter list,
like "No AIS". Go to Preferences, enable "Save current map view as default
view", click "Save". From there on,
aprs.fi will open up with that custom
filter enabled.
