[RFI] rfi from Refrigerator

[Kostas SV1DPI]

Hello
I am new in this reflector.
I found that i have a noise (mainly on 20,17m and 30m bands). This noise 
exists the last week, it is over 9 s units and is periodically. It comes and 
goes every 1-2 minutes, keeps for a while and after that is totally clear 
and agn. Finally i made a research and found that my refrigerator is causing 
the problem. Any ideas what can i do? Do you think that some ferrites in 
power cable of the refrigerator will solve the problem?
