Hello all, I recently received a notice for signal interface at my residence. I have no digital HID lighting. Is it possible my florescents are giving off RFI? Also they have the wrong address on the notice. I assume they just wrote the wrong address on the notice because it was hanging on my front door. Any ideas?

RFI from florescents?

i just bought this nice portable radio a week or so back... noticed that my big old school florescent back lit monitor pretty much jams all AM stations from 0-14" or so approximatly. any farther back, and it drops to nothing.
im guessing this is down to shitty electronics in my monitor... but perhaps you could likewise use a portable radio to determine if the lights are vomiting out too much RF garbage? ive no clue about radio or electronics in general... but it seems to me you could at least compare the severity of the interference to other similar fluorescent light sources to see if yours is particularly bad.
regardless. i doubt the notice was made with respect to rf transmitted interference... just a guess, but it is probably from the cable or phone company?
local line interference if i had to guess. some neighbor possibly has issues with internet or cable or phone service
i dont know where you live, but here in the states most junk is engineered to standards that reduce the possibility of egregious RF interference.
but crappy wiring and crappy cable boxes can push interference out through coax or phone lines... its not uncommon for cable companies to come out and install "chokes"... i think they are called- on houses that are particularly bad.
im just guessing though. im guessing phone and cable technicians can pick up and quantify this interference on those lovely handheld meters that they are always carrying around. they probably found some coming from your place in the course of addressing someones problems.

Check your grounding. A solid ground is key to disposing the harmonic resonance that can cause RF interference.
check grounding - 3 prongs at the wall means nothing. test ground is legit at the wall.
NO looping of ballast cables. zigzag slack somehow, don't loop.
keep ballast 6"+ apart. no cables over lapping ballast
get some of these from RadioShack, put one on your power cord to ballast, and ballast to shade.

get an AM radio, get it on a station that works, start at your equipment and work your way around, find where the signal turns to static and work backwards from there.
good luck. would love to hear an update

is the am radio thing legit? i just made that up.
Thanks for all the suggestions. I ran around the house with am radio and got zero static, jumped in my car drove around the block and still no static. How do I go about testing the ground for my light and wall socket. I'm hoping the cable guy has the wrong address. Thanks again!
there are ground plugin checkers, just plugin and gives you indicator if good ground
looks like you could find one for less than $10
that won't tell you if you ground from the ballast to the fixture is all right though
a cheap electrical meter could be used to check that

We had the same problem here, cable guy drove around with a signal gun shooting the overhead wires...followed the RF burst from our place. The RF was destroying the cable integrity at the neighbors house, I unscrewed the main cable jack in my house...and it stopped.
The cable man offered to come in and "fix" the problem, but I knew what was causing it...my flowering room was in the dark cycle at the time.
I got a Dish, and fuck em all
