compact fluorescent light interference
As energy costs go up, way up, replaced a bunch of bulbs with compact
fluorescents. These things interfere BAD with MW even 40 feet away down a level in my 4 level split level house, low to moderate with SW varying on band. Anyone else noticing this? Listening in the dark these days. |

Screw them flourescents anywhere near my webtv and my computer
equipment.Screw them mf's (Massey Furguson's) F... em! cuhulin |
Trow them flourescents in the s..t can and go back to the good old style
light bulbs you have to replace every couple or tree weeks. cuhulin |

Listening in the dark these days. The cheap imported CFLs don't have a power factor correction circuit which allows all the harmonics into the power lines. I use surplus commercial grade four tube ceiling fixtures with just two lamps (Disconnect the second ballast or put it on a separate switch to give more light with two more tubes.) in my work areas. I got a great deal on them. Nine fixtures were given to me and delivered to my house for free. :) They were a couple years old, but in pretty good shape and they are very quiet, both electrically and mechanically because they are rated for commercial service. -- Link to my "Computers for disabled Veterans" project website deleted after threats were telephoned to my church.

Listening in the dark these days. Been using those things since they first came out ca. 20 years ago. Most are very quiet. Occasionally you'll get a noisy one. Check each bulb, one at a time. My last RFI problem was a Linksys Router, which was horrible. I replaced it with a D-Link which makes no noise at all. |

Let me go look at mine in my kitchen lamp/light.It has Lights Of America
name brand on it and it has four seperate loops,(the bulb loops,sort of like if you was to bend a piece of coathanger wire to make a simple loop) Not counting the brass/copper/whatever it's made of screw in base part,the bulb measures about five inches tall.I once bought a flourescent screw in light bulb at a department store on Ellis Ave (W.T.Grant store,I think it was) that was going out of business back in the early 1970's.That flourescent light bulb lasted in my bathroom for over fourteen years. cuhulin |
All of those new fangled screw in flourescent light bulbs are not the
same quality though.Some of them will burn out very quickly,according to a news article I once read on the internet a few years ago. cuhulin |

I only use one 60 watt equivalent screw in light bulb in my house.It is
in a light in my kitchen which I never turn off.I dont care anything about keeping up with the Jonse's.I am much more intelligent than they are anyway.Elviraaaa,,,,, giddy up,,, giddy up,,, ooom poppa poppa mow mow,,,,,,, cuhulin |
Only one screw in equivalent flourescent light bulb.

The interference from one bulb is very bad. Technically since the lamp is intended for household use, it should be FCC Class B certified. If you can hear it from more than about 10 meters away, it probably is not Class B, and consequently probably should be reported to the FCC. I had a problem with a 175 watt HID, but that thing was never intended for residential use (I ultimately fixed it by building a 2 section low pass filter between the line cord and the ballast assembly). It had a cutoff at about 500Khz to keep the cap and inductor sizes reasonable. |

I was playin with my Panasonic model RF-708 radio when I was settin on
my porcelain throne the other day.Soon as I brought it (the radio) into my living room,it started making all kinds of spooky noises.I reckon my computer and my webtv had it all confused and disconbooberated. cuhulin |
I mispelled it,it is,discombooberated.

Light bulbs are part 18 (Industrial/Scientific/Medical), not Part 15. (At least that's what the GE brand ones said on the packaging). They also said not to use it in a location where there are radios used for emergency/safety services. I had some pretty strange results. I'm using one of those 13 watt ones in my bedside lamp, and the RFI (mostly) went away when I reworked my power from a rats nest of extention cords to one power strip. Even though the lamp is closer, electrically, to the shortwave, the interference is much reduced. So, interference may be related to the physically construction of the power wiring.

My antennas are "OUTSIDE" and "NOT NEAR THE HOUSE". These lights still
interfere with reception............spend a buck and find out!!!!!!!!! "David" wrote in message ...

The interference from one bulb is very bad. Then that one bulb should be returned to the store and exchanged for another. Every bulb in my house is compact fluorescent. I can hear the TIS at LAX from 45 miles away. Before they took over 530 I could hear the Mojave National Monument on that frequency, about 60 miles. On HF I copy aircraft from thousands of miles away quite reliably. I can get Bangalore every morning on 9690. |
I can listen to the Aircraft traffic from the Airports around here.But
to frank with you George,Aircraft traffic yip yap is very boring to me. cuhulin |
