    Subject: Radio interference
          
      I have a new Jabiru 2200 (85hp) installed in a Murphy Maverick with an 
      Icom IC-A200 panel mount VHFand an external antenna mounted throughthe 
      fuselage skin midway between the cabin and fin using the fuselage for a 
      groundplane.
      
      I am picking up ignition interference when receiving which increases 
      with engine speed.
      I have tried running the radio from an independant power supply to 
      eliminate installation wiring and still get the same problem, which 
      seems to indicate that the antenna is picking up the radiated noise.
      Does anyone have any suggestions on how to cure the problem? Would a 
      smaller insulated ground plane help?
