   Good morning Kurt.   
      
   KW> I read that powerline ethernet adapters can cause serious   
   KW> interference in some bands, and I've noticed a lot of RF   
   KW> hum on my shortwave radio.   
      
   Yes we are experiencing a lot of interference from powerline   
   adapters,and there is no authority here on the Aland Islands that   
   can/could enforce the regulations concerning PLC via powerline.   
      
   We are though happy that all electrical and phone lines are buried in   
   the ground, and not carried in the air.   
      
   KW> Does anyone here have any experience with SW/HAM radio and powerline   
   KW> adapters to confirm?   
      
   According to the regulations concerning any PLC transfer, the   
   frequencies that cover ham bands and other important transmissions must   
   be notched out from the transmissions. That concerns also powerline   
   adapters, but trying to get the authorities to take action against them   
   is very difficult.   
      
   Once the PLC signals enter the house wiring they are of course radiating   
   their transmissions all over.   
      
      
   Have a nice day,   
      
   Holger
