In the previous post I showed how to add some icons to an application showing OpenStreetMap, with Python and GTK+. Next, I’ll show how to make a listing of nearest repeaters to selected area. The listing of all repeaters is in the local array, and since there is a .distance(lat,lon) that gives the distance to a point, the list of repeaters can be sorted by closest to a certain point that is selected – in the on_button_release function. The Python Gtk guide shows an example that can be integrated in to the code to add a Listbox. The listbox should be “self.listbox” so various functions can access and change it. Below the other widget/control code, this must be added, within a gtkScrollWindow or adding many items will expand the window awkwardly:Continue reading “Building an amateur radio app for Linux, part 2”

Also unlike most other offline mapping apps it is open-source, available on F-Droid store, and very extensive, and respects user freedoms and an active developer community.
For some time I have wondered why the public domain BLM land use maps aren’t an option in Osmand, I tried mobac but found no way to get the maps I wanted, but after a bit of research I found the answer! Here are the steps to add land use maps to Osmand. Continue reading “Adding BLM Land Use Maps to Osmand on Android”
