I wonder if this is another occurrence of a monster cable up sell? Could be. As an audio guy I'm pretty aware of the whole cable issue. Yes you can spend way more money for cables than seems reasonable. Hundreds or even thousands of dollars. Per foot. In a digital transfer environment I'm

Using higher quality cables (less resistance) can obtain for you a little more distance. The issue is more of noise rejection than it is resistance. Ethernet cable is not shielded (to save money on long cable runs), instead using twisting to neutralize outside noise and internal crosstalk.

Some of the USB cables I get with appliances also include a graphite choke to reduce interference. Some Apple keyboards have a ferrite core on the end of the cable that plugs into the computer. I think that is supposed to limit radiation FROM the keyboard. Not to keep QRN out of the computer.

I see those ferrite cores on lots of cables. I have several analog video cables (HD-15 connectors) with them. Since there is a connector on each end of the cable but the core is only on one end, it's not clear the purpose. There doesn't seem to be any instruction as to which end of the cable

http://hfdesign.otg/tt120199.htm says they are used to prevent unwanted emissions. My understanding is that a wire (e.g. Ethernet, USB cable, etc.) connected to a device that works at high frequencies (e.g. 2 GHz computer) can act as a transmitting antenna. So in a desperate attempt to get

Has anyone tried one of the low-cost secondary DNS services (i.e. I maintain the DNS zone files on my server, but synch to their servers, which have the benefit of being off-site)? I'm looking at zoneedit.com, but not yet sure if that's a reputable service. Also, if I can get backup MX (email

Part of the fix that these provide is the reduction or RF interference given by some of these cables, which in turn cuts down on the interference that is seen by the cable. They were also called chokes. Stewart At 03:38 PM 3/3/2008, you wrote: Some of the USB cables I get with appliances
