Subject: [RTTY] Duplex Outlets - Fire hazard - TVI
To: Group RFI
FYI,

My house was built in the 70's and does not have all aluminum wire, but it 
does have copper coated aluminum wire.

With the recent 6-meter openings I decided to try the SteppIR and Pro III 
out on 6-meters and I was causing some audio RFI on the TV. With the DirecTV 
antenna cable disconnected it was still there. Moving around the room 
changed the level of the RFI.

I unplugged the DirecTV box from the power strip and plugged it into the 
wall socket. The RFI jumped up about 30 db louder and decreased when I 
wiggled the plug.

I pulled the duplex outlet out and it had #12 push in wires that were 
noticably arced and apparently were the source of the problem because 
replacing the outlet knocked out any sign of TVI.

I think is is time to go around the whole house and replace all the outlets 
with the compression type.
