On a couple of occasions I have seen radios where the squelch was set to
low allowing it to break on low level EMI.

Dear Paul etc,
The best, easiest and only solution after many hours of noise is to run
the radio avionics straight to the battery. 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.

The Bosch leads that Ralph constantly refers to on the Jab engine
website are not available in the Northern hemisphere they are peculiar
to Bosch Oz. 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?
Cheers,
Paul

>From what I can see from the work Ralph has done the fixes are
associated with:
Plug lead material, see the picture in the 'files' on the bottom link,
the Bosch cable is shown. 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!
Regards, Clive

so glad you decided to build the floats out of plywood instead of cast iron.
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.
