Agreed - I've got two GFCI outlets in my apartment, that when I tx on 80 m, pop out without fail. Even as low as 5 W...

4) Ethernet. Nothing I've tried gets rid of the hash generated by my network. Although, it's nowhere near as offensive as the other sources.
I have a couple surveillance cameras that make noise on HF. I just turn them off if they are a bother, but I could see that not being an option if the cameras were on a close neighbor's house.
"The best number is 73. Why? 73 is the 21st prime number. Its mirror (37) is the 12th and its mirror (21) is the product of multiplying, 7 and 3. ... In binary, 73 is a palindrome, 1001001 which backwards is 1001001."
-Dr. Sheldon Cooper, (Jim Parsons), "Big Bang Theory"
"Just to invite your attention to "73" in Morse code--also a palindrome."
My Linksys WRT54G sits on a bench under my operating position and creates very narrow birdies on the following frequencies:
73 de Bob - AB8MA
What are the main/most prevalent RFI/emissions sources detremental a ham operator?
73 DE Charles, N5PVL
The "S" word... It's not the socialism, it's the stupidity behind it.
I have the same router and I hear the birdies on 30M only. Thanks for pointing this out.

Electric fence charger.
Washing machine - that one was horrible.
I've not had any noticeable problems with CFL, and I once had every light on then off in the entire house to no audible change.

The most powerful noise source affecting ham radio and AM broadcasting is LIGHTNING, not man made, but Nature's QRN, can disrupt 160, 80 and 60 M and AM BC signals for most of the summer season.
Storms up to 50 miles away in daylight can wipe you out and at night, anywhere in North America can crash thru my QSOs.
Some annoying man made noise comes from small kitchen appliances like electric mixers and blenders !
Noisy motors send out spark noise thru the AC cords and into the house wiring.
My curly light bulbs seem rather quiet here.

In my area:
1. Grow Lights... Three of them within a few miles are destroying the ham bands for about a two mile radius... five hams affected... One loses all of HF every night with 30 over S9 signal. I only loose 40 and 30 meters each night with a 10 to 15 over S9 signal.
2. Power Line Noise, power company is good about fixing
3. Little devices with motors in them... Like my wife's food chopper...
4. The other five hams living within 1/2 mile of me... They operate too much... All but for the one who looses all of HF every night...
