Well, at the end, those new 2.4GHz systems which are coming might solve this problem or even
make it lot worse ... Anyway, fail-safe/save options in any king of Radio are good thing.
Especially for Gas-engines, 2.4GHz systems are inherently lot better shielded against most of
the intereferneces but the problems with them beside the wave-propagations one is that they
are in "baby-age" and suffer from "baby-ilnesses" and it might take 1-2 years more to get
them well in place and maybe replace the current FM radios.
