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?
