Curing the problem at engine level....but sounds difficult if the
cabling is implemented as "manufactured".

I should rather have a look at the radio system. It is required to
shield the microfone cable and shielding the headphones/loudspeakers
cables is also a good and easy solution.

Thanks.

Well, the thing is, I know the drill to try to cure the symptoms of the
interference.

It some work and the result isn't guaranteed.

It's more obvious to cure the cause that generates the noise in the first
place. This also requires some work and is much more likely to be
succesfull.

Since both Schempp-Hirth and DG aren't doing it, I wondered why?

I know several plane owners who reports the same problem. I haven't asked
all i know of, but so far I haven't found any without the problem.

And yes, the easy solution is of course to turn the thing off, which is the
first choice anyway, since gliding is the sport of it.

Having to fly in controlled airspace with the engine on is the showstopper.
