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,

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

now I have unbearable ignition noise - Any of you radio techs out there know of a solution?? Kenneth 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, join this yahoo group:

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

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?? On Sat, 12 Jun 2004 20:20:57 -0500 "JIM VANCE" writes: > The auto plugs should have an R in the number. These

"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??" 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

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
