[Elecraft] K2's and switching power supplies

[Tim Logan]

Hi folks -
I would like to know what experiences anyone has had using switching 
power supplies within close proximity of a K2 or K2-100.  I'm 
considering building a fifth K2 (keep selling the dang things to people 
that don't build) and am toying with the idea of making up a portable 
module that would include a switching power supply. Thanks in advance.
