[Elecraft] Computer Noise ruining 20 & 30m

[Ed Gray W0SD]

Summary:
Based on the answers received and spending all morning reading on the 
WEB it appears  PC Power and Cooling,  Startec and Antec at least at the 
higher end have good computer power supplies. One amateur had good 
success curing his problem with a Startech ATX POW450Pro, two reported 
good results with PC Power and Cooling and one with Antec.  Other 
possibility is Enermax but no testimonials.  A lot of the information is 
in regards to a low DB noise level to the ear and delivering the power 
without a voltage drop. and not much on  RFI/EMI information.  The ones 
listed above do speak of RFI/EMI.   Be sure you buy the right power 
supply for your computer.  They are not nearly as standard as they used 
to be.

Thanks for some great input!
