The memory utilization bar can be turned on to show your actual heap utilization on the Preferences tab of the expert-mode Configuration dialog. This will show the used versus allocated heap quantities.

To actually override your default Java heap limit, specify the -Xmx option after the Java command but before the -jar option. For example, specify -Xmx4000m to allow up to 4000 MB of heap memory. YAAC will probably not operate with less than 64MB of heap.

I do not recommend specifying more than half of the physical RAM your computer has, as some will be needed for the operating system, desktop, and any other widgets and applications you might be running.

Hope this helps.

I noticed that I was seeing the entire world and I was likely running out of memory.

Can someone remind me where to set the range limit?

No, not really. What you did was stop _displaying_ stations and objects more than 100 kilometers away. But you didn't stop receiving and cataloging them in heap memory.

To overstuff YAAC like this, I presume you are using an APRS-IS connection. But it sounds like you connected to port 10152 (the unfiltered full-planet feed) rather than port 14580 (the filtered feed, where you need to specify the filter for the feed you want). Try using a 14580 feed with a r/lat/lon/100 filter expression (where lat and lon are the degrees North and East of the centerpoint you want to receive at) to get a reduced feed of just what you want.

Thank you, Andrew,

I think I found the thing I was after as it was pretty elementary.

Under the Filter menu, I found that I was set to a Range of over 12,000 Km. set that to 100 and things got way better.
