Ramy, for what it's worth, I've been testing my PFB on the ground (both near StLouis and near Phoenix) both in my house and while driving, and I'm seeing PCAS detections out to the max 5 miles consistently, as well as ADS-B targets out to the max display range.

These are the settings I'm using. Software is 2.40, display 3.0.0.

# Set ADS-B horizontal and vertical range in meters.
# horizontal range: max: 65535m For gliders recommended: 9000m
# vertical range: For gliders recommended: 500m
# Testing max range

Vertical ranges are for testing on the ground, and may be reduced after I finally get it installed in my glider.
