@WSCF738 just an FYI, propagation can be very different from what most repeater maps show. Typical repeater maps indicate a perfect circle when in fact, actual propagation looks more like this.
As you can see, there is a dead zone in the square with "Dallas" written. It extends from the lower left of the square upwards. Then you can also see areas of light green much further away than that.
Elevation, trees, houses, buildings, etc. all affect the actual propagation. This is why you can sometimes be closer and not get a signal but further and get a signal.
