[Elecraft] RF hardening a computer speaker.

[Robert McGwier]

I personally have not found beads to be effective even with coiling.
On the other hand, I have found toroidal cores to be extremely effective.
Many recommend a 0.01 uf across the speaker leads.  DO NOT DO THIS.  We
are years beyond the old tube era and many solid state audio devices just
hate working into capacitive loads.  If you have a 0.01 uF across the
leads, get rid of it.  You can really blow a high power stereo easily
with this capacitor trick.

I picked up a set of Altec Lansing Multimedia amplified computer speakers
for a very cheap price. My hope was to use them with my K2 so I could hook
up the computer and headphones and still have speaker output.
