I've had luck finding these kinds of problems by bringing a spectrum analyzer to the site and connecting it to an antenna. I look at 10-20Mhz sections of the spectrum and try to find a spike that comes up at the same time as the interference. It is time consuming and dependent upon the interference happening frequently, but it works quite well. It beats sitting around trying to analyze the problem to death and you feel like you're at least doing something. Sometimes you need to prove where the trouble is not happening help you focus on where it really is.
