I have always made custom GPS settings for my scanners since the days when radioreference didn't provide the data. I have been using microsoft streets and trips (don't judge, it just works and I've adapted to it really well!). In 2020 I am making rectangles for my SDS100 systems. I've decided it's time to switch over to something like google earth. I've found out how to add placemarks and I found how to draw polygons but uniden uses perfect rectangles. Anyone know a way to draw a perfect rectangle for this purpose?
