[1000mp] speaker RF

[ROBERT SCOTT]

Hi Art
      I am using the lead that came with the SP8 I am
sure that yaesu has used shielded cable well I hope
they have.
     I have put on a ferrite and wound as much of the
cable as I could around it and touch wood the cracks
and bangs have stopped (touch wood).
Something I forgot to mention I can hear my voice on
the rigs own internal speaker as well thanks for all
the suggestions I am very very grateful and hopefully
i will get this problem sorted out with all your help
Thanks again 73's Robin mi5rjs
