In my aircraft the avionics switch does not have a bus or anything complicated, run a wire from the battery to the fuse, to switch, to radio etc, back to the battery, and hay presto, no noise and great reception.

James Hallam, who has a Twister with Jab 2200, has had a hell of a time with interference and I pointed him towards a UK company that manufactures plug leads for racing engines that employ the same technology used in the Bosch Oz leads. It made only a marginal difference, and not worth the =C2=A3200 or so quid he paid. I have tried ferrites on the ignition coil leads and that was a total waste of time. I don't know anyone who claims to have found a noise reduction from a grounded shield on the P lead. But removing RFI is a black art and what works in one installation can be hard to replicate in another. I have come to the conclusion that there is no magic bullet. The best thing to do is what Jabiru do themselves and that is mount the aerial as far away from the engine as possible. Of course, if you can get a job at Jabiru or working for Jabiru, the RF disappears. Roger Lewis was deaf to it, I wonder if he can hear it now?

Link to Bosch leads on previous posts (aussie website). Ferrite beads on the Coil HT, never heard of this or thought of it, seems two leads help a third makes no difference. Seems a great cheap and easy improvement. Shielding the P, leads, we all probably know this but Ralph suggests shielding is grounded at the engine end. I did the opposite thinking I might import some RF into the panel area, he also suggests using the shield as the ground for the mag switch, can't see what difference that would make so won't change mine, it does remove a wire so would do it this way in the future. 8mm Ferrite beads are the order of the day! Then new plug leads!

Hi Doug, Well, once the molds are made, I guess you could make them out of about anything - fiberglass, chocolate, or even cast iron. But Ryan did order a set for you today, and he specified cast titanium. Shouldn't be too heavy, but we do have a mod that puts a jet boat motor and nozzle in each float. Those motors will get you up to a very fast taxi and put you airplane "on step" so that you are now high enough out of the water to start the aircraft engine. If you don't use the float jets, the prop hits the water and sends out lots of spray - wears the paint off the prop tips as well. See you at SNF.
