John,

I've used a handfull of #31 split bead ferrites from DX engineering on the wire harness to the COP spark plugs.
Second I use the Clear Speech DSP speaker, now available from Heil Sound
I reckon the Clear Speech unit is more effective than the DSP unit in the Icom 706MKIIG.

cheers, Dick

  Thanks for the info.  Say, WHAT DID you do to kill noise from the ignition into the radio?  Mine is a solid S-9 with the engine running...kind of makes it difficult to communicate!  I've tried improving grounds (the antenna is very well grounded) and I have a separate auto battery in the trunk with the radio (remoted to the car).  I've totally disconnected the battery from the car's DC electrical system and the noise still persists...so it is not coming in via the DC lines. And it is definitely ignition noise.
