[Elecraft] QRN-less Wireless Router?+QRN From Linksys & MFJ Devices

[Graham Haddock]

Based on some of the comments on this email reflector in the last week,
I went hunting for noise this weekend and discovered the worst offender
in the house was the switching "wall wart" power supply for my Linksys
wireless router.  I will replace the "wall wart" with a linear regulated 
supply
of the same rating, and I expect most or all of the noise to go away.  
The Linksys
box puts out a few spot carrier tones or birdies, which will still be 
there, but the
broadband S5 hash was coming from the "wall wart."
