I have not had a chance to go to the job and try it. I don't think it is going to help but I want to keep an open mind. I will have to go to this job within the next 10 days - and plan on trying it then. Currently, I have the emitter placed in the upper right quadrant of the IR window and it IS working nearly 100% of the time, so I am reluctant to "disturb" it. I also talked to Joe Spinelli at URC and discussed the problem with him. They were trying to get their hands on a unit to do some testing. I emailed him my file, and he looked at the IR carrier with a IR utility that he has. Based on what he saw, he also felt that the remodulator would not help - but hope springs eternal.
