[SEDXC] APOLOGIES TO UVERSE

Hi Ralph and Dave,  I can send you a pix of my P3 noise.  I use max span of 
200 Khz and look for any repeating signals coming out of the noise.  Mine 
were every 60 to 68 Khz and each one around 30 Khz or so wide.  Switchers 
use a switching freq anywhere from around 15 Khz to 60 Khz but could go 
higher.  Switchers are great as long as they work properly but in a real 
world things do go wrong.  Usually the worst you got from the old linear 
supplies was maybe some hum one the caps started going bad.

I used a small rechargeable Gel Cell battery, 7 Amp hour.  You can buy them 
at Dayton pretty cheaply but be selective as there are some dogs up there as 
well.HI.  You can buy locally but more expensive.  I would be interested to 
hear your story as you go forward.  There are so many electronic devices in 
the shack and home these days that can hurt us on HF.

Dave be wary of the UPS systems as I had a friend with one and it wiped out 
40 M.  I have one of the little Eton all band receivers and it works very 
well using the loop stick for DF ing.

Unfortunately it seem things will only get worse for HF with the products 
they sell these days,  73 Mike

Gosh Mike that was a very interesting story.  Man I can really feel for you.
These problems can be nightmares.  I bet I have 10 to 12 wall warts in the
house here.  I see verticals bands of noise on my K3 panadapter too and
wondered what's up with that.  Good idea with the K3 and panadapter running
on battery.  I think I will try that trick and I should be able to tell
pretty fast if that noise is generated in my house or not.

Thanks for sharing your story.  Good luck with your "other" neighbor!

73, Ralph K1ZZI

Okay, so I like to eat crow.  The Uverse super came today and was very very
pleasant gentleman to work with.. He came here first and looked at what I
had.  The went to the house in question and disconnected everything
regarding Uverse inside and out.  No help so he is in the clear and the
neighbor said he had no service interruptions.  I have been transmitting on
160 and 80 in the last few days.  So they are in the clear.  The Uverse
super and I had talked about killing the breakers and the neighbor was okay
with that.  The Uverse super stayed and talked to me over the phone as they
pulled every breaker.  No change so I am flabbergasted at the time as I had
gotten into a mind set of this is the house as everything pointed that way.
My hat is off to Uverse as I jumped the gun but it seemed so right as they
had just installed Uverse when the problem started.

I went up into the subdivision and did some more DF as crude as it is with
the loop stick AM radio.  It now looks more like the house next to the
original neighbor but he pointed out to me she was going to be hard to deal
with.  So I am hesitant to get involved with her.  I may see if I could get
some help from the power company to at least kill the power to verify the
right house but they may not be receptive to that idea and I would
understand.  ARRL feels it is a bad switching supply putting the switching
noise back onto the power line.  I guess I can hope it will eventually quit
working. We are getting into the summer season so maybe I can get by for a
while and build more antennas at the farm site where I only have to deal
with power line noise which is easy to correct normally.

I had a bad wall wart switcher that powered my Comcast cable box go bad a
year or so ago and although it caused a good amount of noise on 160 M it is
no where near the problem I have now.  I did kill the house today with the
K3 and panadapter on battery to prove I was not loosing it.  I am trying to
get rid of every switcher the house. Even my TV in the shack even has an
outboard wall wart switcher.


Beware of switchers. 73 Mike
