Dave, I checked the link but it seems broken. Can you give us a few
details? Freq, antenna, time and etc? This sounds quite interesting.

BTW, you are lucky - My neighborhood does NOT have buried powerlines
(in fact, we have more than our share of aerial cordage) and the noise
levels reflect it. Light dimmers and other noise sources are legion.
Did get some good copy on hams from South America the other night on
40, though - but still have to wait for the sunspots to rise again
before the subkilowatt fleas come banging through again.

I will say, though, that the newest types of spiral fluorescent bulbs,
when new and working properly, give off no perceptible RFI. I am
impressed.

Try this. I screwed up.

The nice thing about having a license is you can theoretically make
people stop using noisy dimmers.- Hide quoted text -

Theoretically indeed.

Well, not completely true. The better (read more expensive) dimmers
include "radio frequency interference suppression circuitry". You get
what you pay for.

It wasn't the political stuff that ruined this group. It was all the
HD-radio, IBOC crapola. The IBOC discussion has largely died down
since the proponents of IBOC grew tired of trying to convince people
that 2+2=7, but the damage is done and it is irreparable. I learned a
lot in this group, made the best of it by getting my ham license and
have never looked back. And I still like to drop in once in a great
while. The group would have to have a moderator or SOMETHING though
before it could recapture any past glory. As it is, any good
discussion of shortwave is going to be interrupted the second someone
like Jose Eduardo (or whatever his name was) shows up with some
cockamamie BS to spout.

Hi, Joe - I guess I've seen these, but I've never trusted them - have
you had experience with their improved circuitry?

I have.

Not so good. They do reduce RF emission, but they don't keep the
spike off the line, which creates most of the problems associated
with dimmers.

I pulled the SCR and Triac dimmers from my house and replaced
them with in-wall variacs where I absolutely had to have a dimmer.
VERY quiet.

Truth is, I don't really need dimmers in the house. Where I'd
want mood lighting, there are multiple sources in the room, anyway,
I put half of them on one switch and half on a second switch, and
then simply turn on the level of illumination I want or need.

Outdoor dusk-to-dawn security lights are often as much noise as
dimmers for us in the radio hobby. The most common solution is to
use a screw-in security light/socket in an outdoor fixture. These
screw-in solutions are usually SCR/TRIAC dimmers in a different
configuration. Intermatic, however, makes these devices without
SCR's, TRIACs or any other similar device. Intermatic devices use a
photo sensor, a time constant, and a closure which eliminates
flickering in lightning flashes, as well as radio noise. Intermatic
screw-in security light solutions are only fractionally more
expensive than the cheap crap usually found on shelves. I mean,
like, a buck or two difference, if that. End of problems.


There is more elegant solution, and that's a separate photo
sensor connected to the line that feeds the security lights. Also
using a closure, these produce zero noise, no flickering with
transient changes in ambient light, they can handle large loads
without difficulty, and you can adjust their on and off conditions
for optimal performance. For this application, I, again, use
Intermatic controls. $12, takes 15 minutes to install. The
instructions are clear, concise, and everything you need to do the
install is in the package.

And no soldering is required.

No light dimmers here.When I want to ''dim'' my lights I turn them off.

Had to strike a match to see if that light was lit!

Hey, good, creative comeback.

It's because of half-wits like Mr. Lare that many people don't bother
with this potentially-useful forum for information exchange.

Half-wit? Like you, 'tard boy?

I opted to move out of the ghetto.
