Two or three weeks ago I saw a UK website about some new little
ferrite cores that are intended for use on cellphone earphones.They
clip on the cellphone earphone cords/wires.Suppose to help drain off
cellphone microwave energy.They might be handy for shortwave radios
too. cuhulin


The same cores that work at 800, 1.9GHz, 2.4 GHz will likely not be
useful at HF.
The whole idea that reducing RF on the earphone will be beneficial is
nonsense.
Right along the lines with the PC card antenna that fits under the
cell phone battery.

I don't think the ferrite cores for cell phone headsets are for improving
reception--they're for reducing your chances of getting brain cancer. If
they make a difference in this regard, who knows...
