[Elecraft] Plasma TV Noise any ideas on how to filter it out.

[Jim Wiley]

You guys are aware, I suppose, that interference of this level and 
duration clearly qualifies as  the type of interference that merits 
direct FCC intervention.  File a complaint.  The resolution process will 
take some time, but you will win in the end.  The FCC has the power to 
force your neighbor to stop using the interfering device.


But, remember the golden rule of interference:  "If no one complains, 
it's not interference".    Unless you raise an official complaint, you 
have no one but ourself to complain to.  


One thing that works almost every time is this correct  statement:  
"Your TV is not supposed to radiate interference, but it clearly is.  It 
certainly is not supposed to transmit signals.  That means it is 
defective somehow.  I have no idea what the defect could be but, your TV 
_is_ an electrical device, and if it is defective who knows what could 
happen.  I hope it doesn't cause a fire!"  Works best if mentioned 
within earshot of the neighbors wife.


Good luck.
