  • Well. If it negotiates a lower bit rate I’m pretty sure the audiophile level kit will tell you it’s no longer 24 bit 96khz or whatever the cool kids use now.

    But I’m pretty sure most High bitrate systems will have some level forward error correction, when the cable cannot deliver the snr needed to repair errors the signal will usually completely drop out. It will be perfect then gone.

    Without error correction, random bit errors in digital audio are seriously jarring.

    Having high quality (in terms of screening and contacts) won’t have the kind of subtle change it can have with analogue signals. With analogue you’re fighting things that can be minor like induced noise.






  • I do kinda see some point in gold plating electrical cables. Gold doesn’t tarnish so much and is also often used on computer edge connectors.

    The issue has always been “audiophiles” telling you they can tell the difference with a gold or gold plated digital connector. Of course you cannot, you either are getting bit errors or not with digital audio. But they do generally provide a more reliable connection overall.

    Now don’t ask me about my opinion, you’re talking to the guy that makes radio antennas with speaker wire. I am truly uncultured in terms of electrical connectivity.



  • Are you sure it was dot pitch and not dot clock?

    Dot pitch on a crt might make the image look bad (trying to draw onto the shadow mask) but I doubt it would damage it.

    Setting an invalid dot clock could damage some crts. But most of the modern (read from mid 90s on) would just go to the power save mode when they got a clock they couldn’t use. The warning did still remain on the xfree86 configuration guides though.

    Showing my age perhaps.






  • That’s a tough one. But if they’re going to operate in a way where they don’t want Venezuelan authorities to know they’re there (I got the impression they were making a show of force so…) they do need to inform the atc of friendly countries operating nearby so they can ensure flight plans keep them apart.

    But, I don’t know what (if any) procedures they have for this kind of thing. But to me it makes sense, you either close the nearby airspace (kinda makes it obvious something is going on), inform friendly atc so they can keep squawking and non squawking traffic apart. Neither just makes aviation extremely dangerous.


  • To the best of my knowledge the ads-b transponders operate with the same interface as previous transponders. That is they can be active, stand by or off. Commercial airliners should never turn them off in the air, but they do have the ability to.

    For military aircraft this requirement is almost certainly only going to apply when in “friendly airspace” and at altitudes with commercial traffic. Especially when not on an operational mission.

    For truly secretive missions they will likely get blanket clearances in friendly airspace to travel at specific altitudes so they can travel transponder off while avoiding the commercial traffic.

    But I’m not an expert by any means.
