I am having difficulties with my RF to IR emitter base. It appears to be getting a lot of interference. You can actually look through the window and see the led flicker randomly without me pushing any button. You can see a nice continous flash when I push a button. Needless to say The RF function of the remote is useless. If I drop the antenna on the base it works great and their is no flashing. Only problem is I have to be next to it. What is the frequency of the RF signal from the remote and what other things broadcast in that range? Thanks.
