My results are as follows, ferrite beads are your friend...I have been  
experimenting and found that if i attached ferrite beads to the mains power  leads 
that are on the street side of the mains panel just after the meter i have  
been able to pretty much eliminate all types of rfi that i was plagued with  
before. The type of bead is 43 mix that i am using.i found a novel way of  
attaching the beads to the mains cable i take a 8 inch piece  of  2 inch pvc and 
split it in half i take 2 end caps and bore a 3/4 inch hole in  each end then 
split those in half now i take the 2 2inch pieces and  put  them around the cable 
and glue them together using pcv glue then do the same to  the bottom cover 
pieces i take aprox 10 ferrite beads and smash them to bits  then pour that 
into the tube fill to the top and then glue on the top  cover. rf inquiry sell 
this product for 200.00  you can duplicate this for  about 30.00     73 ray nr1r
