Topband: RF interference from 160m to GE Electric stove

[Herbert Schoenbohm]

Try several clamp on toroids first.  Four spaced on the cord to the plug 
and run a separate ground wire from the stove chassis to a close by 
ground rod.  Also you could try to put some .01 at 600 volts from the 
stove power input to ground.
