[Elecraft] Switching Type Supplies with K2

[W3FPR - Don Wilhelm]

The K2 is no more sensitive the RF hash from a power supply (or other noise
producing devices) than other radios.

BUT - since the K2 is more sensitive, and can receive lower level signals of
any kind, yes it will hear even weaker RF signals - and if the RF hash from
a power supply can reach your antenna system, it will be received just like
any other signal.

A lot does depend on your antenna system - which includes the feedline right
down to the transceiver.  If your feedline picks up radiation that is
generated in the hamshack, any transceiver will receive it just like a
signal.  The cure is to install a proper feedline that does not radiate (if
it does not radiate, it will also not pick up signals) - a proper antenna
system will ideally receive only signals that appear at the antenna.
Unfortunately, not all antenna systems are perfect in that regard.
