made. My room was upstairs in a loft setting. My folks bought two very

You have me beat. I was a free range hippie in 1969 in Hollywood.
Since I had no real permanent residence except for my live in 'boy toy'

much fun with the mother/daughter thing I didn't care. Great year, 1969.

OK, since you asked, I did totally unplug the power strip after
unplugging the offending lamp. The noise did go down due to some of the
wall warts having switching supplies in them. It is the background noise
of the neighborhood that is killing my DX'ing. I have a battery powered
marine RDF to chase it down but as of today I can't find it under my
huge pile of stuff in the garage. Whatever the noise source is, it does
not follow a pattern like an SCR lamp would do. There is one big spike
at the peaks of the 60Hz power cycle that is caught by my Hammarlund's
noise limiter, but the rest is too random to be from SCR's.
All I have found out so far is that it is not coming from my house.
Looking at the audio out with my scope the frequency pattern appears to
be about 600 to 1200 Hz, but with a nasty amplitude. Since my scope is a
2245A Tektronix 100MHz analog and not a digital I can't take a one shot
picture of the noise. I tried with my digital camera but after about ten
attempts I gave up since the camera shutter speed was too long for one
trace. Since my neighborhood is not anywhere near any industry and the
noise is always there I should be able to track it, but again, I need to
find that danged RDF.
