Buddy says he is experiencing intercom noise. He says it goes away below 2200 rpm.
Radio is the Garmin GTR-200, a unit highly susceptible to RF noise. We are running ten of these radios and put up with interference from ground emitters and approach control bleed-through, but he says he gets it all the time, and he is sure it is intercom noise. The intercom can be turned off, of course.
Engine is a factory new O-360 in a Super Cub with Slicks. The engine has 1000 TT, and the mags were redone 300 hours ago.
So - assuming the mag filters have died, he wants me to buy new ones and install. Before we do that I will ride with him and try each mag individually.
But the question: are the $95 filters as good as the $300 filters? Spruce sells both.
My impression is that Slicks don’t even need filters. Am I wrong?
