It is.  How much difference it makes I can't say.  They built
military versions with more radio suppression I'm pretty
sure.  Frequency-modulation schemes like FM broadcast radio aren't
bothered by spark noise unless it's enough to melt the radio (so to
speak).  My '89 hasn't got one, but the '84 did.  I never pulled it
off to see the difference on AM.
