I have a rdp149 that was originally setup to work with an open array radar. I purchased a used rsb0071 to switch over to the dome setup. Well, I hooked it up and changed the radar type to the 2nd option(1834) and it does not show any detections on the radar screen. I have verified the radar is actually spinning, but again it does not detect anything. I have hooked the radar to another rdp149 I have and it seems to work fine on that unit. Any ideas? Thank you for the help!
