RE: the noisy ignition Jabiru.
http://www.aircraftspruce.com/catalog/eppages/magnetofilter.php
My Viking / Continental/ Bendix mags was noisy unitil I installed these
capacitors in the P leads. Then it stopped. I really don't know enough
about it to explain the mechanics of this, but it definitely took the noise
out of the audio. I assume the Jabiru mags have a p- lead somewhere, is
there any kind of filter on it?
I'm sure one of the geniuses ( my boss used to call us F*****g geniuses), on
this list can find you a $.97 Cap that will do the job, I'm ashamed to say I
paid $35.00 each for thes for my certified bird.
Are the Ignition wires shielded style? I was told by an avionics guy ( King
factory type years ago) that a small amount of extra resistance in an old
plug wire , or a bad shield will make it noisy as well.
Hope this helps.
