[Elecraft] k3 switching supply

[Howard Hoyt]

Hi all,

The issue with PS-induced noise is not simple, it depends on several 
factors: transverse noise from the supply (RF current riding on the DC 
output) as well as common-mode due to PS input-to-output impedance.

Thanks to Jim Brown, K9YC for the sanity check while researching the 
issue, and helping identify yet another reason to ensure common-mode 
choking of antenna systems!
