[GCARC] RFI Issues With A Neighbor

[CHARLES Colabrese]

RFI from plasma TVs is a well known problem.  Thank goodness they're not being sold anymore and are being replaced with LCD sets.  
Here is a link to an ARRL Forum where the problem was discussed and some possible solutions offered.  It discusses both Conducted and Radiated interference.

And here is a link to an article on the DX Engineering Technical Support page addressing the same problem.

Since this interference is from a neighbor's TV I suspect it is probably radiated interference being picked up by your antenna.  The ferrites or line filters may work but I doubt it since I don't think this conducted interference. 
The noise reduction built in to your HF rig may reduce the problem. It's worth a try.  Unfortunately, I don't think there's much else you can do in this case.
