First TK-880 range test.

Mrs just left work, 
You can see my issues with terrain and line of sight. 
Antenna is on a 50' pole,  so at about 480' elevation, but just mile to the south is HorseShoe Mtn, 
500 to 550', I need that antenna up another 50' minimum to reach the city. 
We've learned where we can get a good signal. 
Mrs was able to reach the Repeater from down there at work for a bit then the shadow of the ridge got her. 
Not bad for the TK-880 I just installed in her Jeep. 
Get on a ridge it does reach 40 or 50 miles to South, East, West. 
North is the Ozarks and everything gets higher from here.

You might find radio mobile online a useful tool; it'll let you map expected propagation based on topography, vegetation, and built up areas. It does point-to-point link calcs as well as general propagation. It's free for ham and GMRS frequencies: https://www.ve2dbe.com/rmonline_s.asp

The trick to getting accurate results is to turn the required reliability up to about the 90-95% range.

Made my own up,  areas we have tested, there is a few ridges to the South east as far as 35 miles away can hit my repeater from. 
Surprises my jeep buddies they are 40 miles away and hear me answer them...  At least the ones with better Midlands, 
I keep telling them forget Midland, even when I used CB's still I never liked Midland.
