I have problems getting the radar to notice anything at all from air to ground. I have a few targets around the runway and one further away on the hills behind KSC (equipped with weapon managers and set to a different team), I take off, get some distance and go for the first pass, radar recognizes all targets just fine and I can fire. However once I've flown over the targets and turn around to make a second pass the radar goes blind and finds nothing but the one that's up on the hills. However I did do a test in this situation and launched a Jdam and suddenly the radar screen lights up and finds targets.
I have a few mods installed, none of which should affect BDArmory but love if I know tbh:
Adjustable Landing Gear
Chatterer
Distant Objects
Docking Port Alignment Indicator
Editor Extensions
Environmental Visual Enhancements
KER
Infernal Robotics (+Kanadarm)
Scansat
Kerbal Alarm Clock
