Apparently the issue is not resolved. When I came back to the field to actually fly I conducted a range check which produced uncommanded movement at about 15 - 20 feet in all orientations with the receiver light blinking/flickering. The only difference between this check and the previous successful check was other radio traffic, which shouldn't matter. A flying buddy had his SD-10G, so we bound my airplane to his radio. The range check also failed. At this point I think it's safe to say that my transmitter is not at fault. The issue lies with either my setup or the receiver. To further narrow things down I am going to borrow an Airtronics receiver from him for testing purposes. If I get problems then I know my setup is still somehow at fault. If it works then there is an issue with the receiver. I will provide an update this evening.
