[RFI] Direct TV DVR problems

[Tom Horton]

Howard, Kelly,
 Thanks for the suggestions. What diameter are you talking about? Beads, snap ons, or multi winding cores? 
 Wher can I get larger mix 31 cores if so?
 Thanks...

Along that line, my DirecTV HD receiver made loud thumping noises when I
transmitted with 100w on 30 meters. I found two old 1-3/8" I.D. toroids
taped together, possibly a 73 or 77 mix, wrapped as many turns of the
incoming coax around it, and the thumping disappeared. 31 mix would be my
choice nowadays.
