I was playing with uiview32, but I was very bothered by the map that comes with uiview32. So I went looking for another Aprs client for windows. I ended up at PinPoint. In PinPoint you can choose from 40 different Map providers. Very nice.
I am satisfied with how it works. It is clear and fast. Only found out if at “Tools> Options” something changes you have to close the program and restart. There is also something disturbing, if you close the program and restart you have lost the received aprs messages. Very annoying.
