Need to find out if they are amplified speakers. I find the best way to 
get rid of this problem is one or all of the following:
       1.   Run shielded cables from sound board to speakers.
       2.   Put ferrite beads or toroid cores on the speaker wires.
       3.   See if problem occurs if something is plugged into the line-in
       4.   Find out if the speakers pick you up without being plugged 
into the sound board.
       5.   If only in sound board, check on mixer settings to see if 
you are coming into the
             wave, line-in, cd, etc. This might help you to isolate.
       6.   Be sure your equipment and shack grounds are good.

Hope this helps are gives you some ideas.
