I have gone through this.  I disconnected the remote open switch at the 
opener.  The problem went away so toroids at the opener end of this 
cable worked fine.  With the newer openers, the cord to the safety 
switch/light may also bring in the RF.  Anything connected can bring it 
in.  I also use toroids on the A/C line because it is a GFCI and was 
popping off with RF.
