Ken,
The wider plug gap will cause the voltage to build to a higher value before the
plug fires. This in turn releases more peak RF energy in a shorter time when
the plug fires. This produces a much stronger RF pulse; not good if you want
the best radio communications in the aircraft band, but
Due to the high cost of aviation plugs I decided to buy the Revmaster
conversion kit to auto plugs-that being said the
engine runs excellant but now I have unbearable ignition noise. If I had
to do it over I never would have done this. Any of you radio techs out
the know of a so

now I have unbearable ignition noise - Any of you radio techs out there
know of a solution??

There is no doubt that you can solve your problem without too much
trouble (or $$). You will probably get some good advice here - if not,

Thanks Steve--I already sent them an Email.

The auto plugs should have an R in the number. These are the resistor version
of the standard plugs and will greatly reduce radio interference (Rotax changed
their plugs to resistor type for this reason). If all else fails, buy some
metal braid that is used for grounding straps, etc. Put it o
Thanks Jim-Someone told me the power wire to the radio needs to
be sheilded as the eng noise is conducted through the radio via this
wire??

"Someone told me the power wire to the radio needs to

A power filter can be fitted to the power bus of the radio stack. You can see
similar devices attached to most car stereo power leads for just this reason.
Ken,
A brute force line filter at the power inlet of the radio stack is great
insurance. Then it's not important to have a shielded power wire.
The ignition noise can be getting into the radio on the power wire or on the
antenna. One quick check is to have the engine running and disconnect t
For those of u that responded, Joe at Revmaster said what did I gap the
plugs at, I told him since no instructions came with them I took the
average of what they were gapped at in the box and set them all at .030.
He said that is probably most of the problem, regap to .016 they are
trying too ha
