Basement QRN

Discovered another reason I don't like them spiral lights with the nasty mercury
in them....I have been plagued by QRN.....and once I "heard" that it was a very
regular pattern(like a fast motor-boat) I went hunting....

Sure enough, one of them modren, don't use much power, lasts a long time toxic
material containing bulbs was ossylayting to beat the band....

Now, I have unscrewed it and have packed it away in a shock proof transportation
carrier so that I can legally transport it to one of the two approved
faciltities around here that accepts them...and hope that it doesn't break and
force me to report myself to the Maryland Environmental Police so they can
condem my car and force me to hire a toxic waste hauler to take the car with the
shattered bulb to the approved disposal facility.

Re: Basement QRN

Did the problem go away when you replaced it with another of that
type - i.e, was it a defective bulb? Or do all bulbs of this type
give you this problem? I have several of them here and haven't
noticed any problem, but I might have missed something.

I have one that's right over the rig...and as far as I can tell, it isn't making
noise....I unscrewed it and there was no difference in the QRN.

What I did notice is that the light from the defective bulb was rapidly
pulsating...but you had to look very closely to notice it.

So.....one night I will turn off all the lights in the house and see if the
background noise gets less.

Thom and the group,

I have had a terrible noise on 40m for quite a while and I thought (big
mistake) it was really band noise.

Last Thursday evening just before the Fox hunt, I decided to really
determine if it was band noise or "in the house" noise.

The CFL's, computer, and computer monitor were fine. The last thing I
powered off was the brick power supply for an external IDE hard drive
that I use for backups. The +20 noise dropped to nothing. Plugging it
back in produced the +20 noise again. My K2 with the KDSP2 sounds
better now than it has sounded in a long while.

I never realized just how noisy those small devices are. Hope this
helps someone else....

Regards & 73

Re: Basement QRN

I can report exactly the same thing! My external USB drive's power supply
is absolutely atrocious. I had blamed my high noise level on everything
else first. I'd even turned the computer (mac) off, and that made no
difference! Sometimes life is just too complicated!

Re: Basement QRN

One very good thing about Macs - I haven't heard of a single instance of
noisy psu

CFL QRN

In reply to this post by Stephen Prior

Every lamp socket we have is occupied by a CFL bulb.

No sign of noise.
