You may want to check your emitter outputs and base station location placement. There have been numerous comments lately about RF interference, and in many cases it points back to newly introduced equipment and/or questionable HDMI cables. As the MRF-260 RF receiver is integrated in the base, it's getting tougher to isolate the antenna among all the RF producing gear. Maybe try the MRF-350 and extend the antenna. Better yet, add a MRX-1/RFX-250 and you'll get both MX-Wand and MX-iOS operation.
