Doesn't some of the surveyor gear try to lock onto the frequency to improve accuracy, even if they can't decrypt the signal? Also if you know where the source of the jamming is coming from would it be possible to use that information to over come some of the degradation? _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
