Have to disagree with Tom's advice here. It is never a good idea to briefly/temporarily change channels within a licensed band without consulting a qualified frequency coordinator.
We did consider interference as a possibility once upon a time, but consulted with our frequency coordinator before trying a different channel plan. Only after indentifying a second available freq pair did we change channels briefly/temporarily just to see if interference was the issue. It was not. While interference is possible in the licensed bands it will most likely be caused by someone "briefly/temporarily" changing channels when they shouldn't. You can also simply turn off the transmitter on the far side and view RSSI readings. If they show higher than what your expected noise floor should be then you might have an interfering source to hunt down. Simply changing channels at will briefly or otherwise within licensed bands should never be attempted.

Licensed gets interference to. If your MSE is showing Interference its very possible that is exactly what you are having. You may need to briefly/temporarilly change channels to verifiy.
