Ron, before you go nuts with fixes & mods, do a little noise-sniffing. Take
a 2M H/T, and a portable AM radio out around the neighborhood, and see if
you can find any potential sources for the noise.

Bear in mind too, that the noise doesn't have to be locally produced. It is
theoretically possible (and has happened more than once) for the noise
source to actually be several miles away, but part of the same grid. One of
our local hams had a problem several years ago, and the source was a touch
lamp, 1.5 miles away...

And don't be afraid to ask Duke to help you in searching out the noise
source - if it's theirs, they are obliged to find & fix it.

Background: Within the past several months my QTH which was virtually a
very low noise environment now is one of the nosiest QTH's I have ever
lived
in. Birdies every 17 kc across 160-80 and 40. Some nights its worse with
birdies every 5-7-kc. These are not low signal strengths either but up to
a
S-9+ on 80 meters.
have check with all of my neighbors since initially it would start right
at
5 PM and last all night until 7:30 in the morning. My first thought was
an
auto light fixture. Well it's gotten bad and doesn't seem to be on a
regular time schedule. Feelings are TV or touch lamp. Possible PC but
don't know. Power company is Florida Progress which is a Duke Energy
company. Have heard that Duke is playing with their new Internet access
over power lines but I do not think it has hit the central Florida market.

Question - I am thinking about trying the MFJ-1265 Noise phasing unit.
Have
read an old review on ARRL and other comments on some bulletin boards but
am
wondering if anyone out there has experience with the unit and what their
honest impression is. In addition to that unit I plan on a complete
rework
of the antenna and grounding system her just to make sure I do not have a
poor joint in the system that is providing some rectification and being
self
induced. Any comments will be appreciated.

Again thanks to the list for accepting this inquiry, I respect the
expertise
of the this group.
