Rick you are almost certainly right about the wall warts. That may be why some of us are 
watching our S-meters dangle around S4 - S6 a lot of the time these days. It's annoying, 
but that's the way it is. My house has a few wall wart PSUs running, and I think almost ALL 
my neighbors do too. 

I was tracking down a really bad S9 noise and it finally led me to a fancy Chinese made light  
fixture in our kitchen. We bought it "on sale" a while back. It came from this expensive, 
designer lighting store in Orlando. I turned that thing off in the kitchen and "boom boom - out 
went the noise" in the ham station.  It dropped from S9+20 dB on some bands to S4. On 
others it was not so bad, but that darn thing was a horrible transmitter. So much for 38 years 
of bloody deregulation!

If the XYL is cooking and turns it on I can't use 40m. the little power supply inside that thing is 
going to get replaced. 

Here is a picture of that light fixture in case anyone is interested. Yes, I know - we are crazy 
artists and musicians at this house...


Oh, that earlier remark was a musical reference to a Little Walter song from the 1930s. Boom 
boom, out go the lights. 

73 to all,
