I seriously doubt that a connection to earth has anything at all to do 
with the observed problem. Rather, I suspect some fundamental problem 
with a bad interconnecting audio cable from the computer or microphone, 
an antenna problem, or simple mis-adjustment of the microphone gains (or 
gain the the line input, if computer playback was being used).

Remember that there should be a bond (short, fat copper) from chassis to 
chassis of every piece of equipment in the station, and this collection 
of equipment must be bonded to earth for safety.
