It certainly won't hurt but I've found those measures
hit and miss. They are based in sound engineering but that RF
sure has a way of getting past filters through such things as
the chassis ground or the microphone and speaker cables at
times.
One might have to put a big toroid on each lead of the
power supply as well as each side of the AC power cord.
One way to make a switcher real cheap is to eliminate
all those heavy expensive toroids and shunt capacitors. The
supply will run a computer just fine and be very light to carry
around but can double as an all-band transmitter. I am proposing
a new certificate. It's the WACPSAWAB or Worked All Continents on
Power supply At Once on All Bands. Good luck.
