K5EHX has very cool feature where you can check the repeater coverage over local terrain. Here is a view of Mount Ord Arizona. Ord is over 7000 feet tall and using the coverage feature on k5ehx you can paint the terrain to see where you will have coverage. If your location is “painted” like in the Ord photo below you will have coverage.
Take a look at the video below and let me know what you think.
