Re: [TowerTalk] Halogen Bulbs - 1.8 Mhz RFI

["Floyd Sense" <fsense@copper.net>]

Javier - It sounds as if you are using low voltage halogen lamps - is that 
right?  Chances are that it is the power supply responsible for the noise, 
not the bulbs themselves.  I have 120 VAC halogen bulbs all over my house 
and not a whisper of noise.  I understand that some of the low voltage 
halogen fixtures are using switching power supplies and if that is what you 
have, I doubt that there is much you can do to silence them.

Subject: [TowerTalk] Halogen Bulbs - 1.8 Mhz RFI


I found that the halogen bulbs that were installed few days ago to replace 
my room lamp produce RFI in 1.8 Mhz while the switch it´s on.

I am unable to pull it out because are inserted into a false ceiling I would 
like to know opinions about the correct placement of ferrite chokes or ideas 
that could help me to solve the situation.

Actually I am using an AC filter between the wall socket and the rig power 
supply.

Ideas welcome!!!
