Hijacking this bit of information... Is it in theory possible that this may be the source of some problems I experience receiving DAB radio, using a multi- element directional antenna, regardless of orientation, in a location with reception from at least two and possibly more than four senders within eyesight, or close to that? It's a completely different manufacturer (Siano) and the problem disappears when I simply use a short indoor whip antenna with adequate S/N ratio. Note that so far, I haven't been able to extract more than a subset of the metainformation which accompanies the different audio streams, and I've had other hardware problems, but I've been puzzled why I had not been able to overcome the regular periodic mangling of the audio. My knowledge of DAB is dismal, to start with, anyway. So be gentle. Unless you don't feel like it, or need to let off steam. Or whatever, treat me like a dog... thanks, barry bouwsma -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
