Thanks for the responses. I understand it seems like a waste to use the mrf-350 w/out emitters, but I don't see another option out there. I have line of site to my system, but it's unreliable already because I have to occasionally move the remote and angle it around the rungs in my ht stack. Everyone knows how annoying it is to have a macro only fire halfway through. It's unclear to me why the front blaster of the mrf-350 would be such a poor solution? Is there interference?
