Hi Folks, I've been subscribed to this list for about a year. I've read through much of the archives in the past. I'll admit the answers to the question[s] I pose are probably found somewhere in the
Hi Mike, This kind of interference may be from the equipment rater than the connectors or cables as the equipment pretty much stops when nothing is hooked to it and although others will probably disa
This is an interesting discussion. I would add a few points/questions: -Does anyone know of published "typical" spectra of 1000baseT vs 100 vs 10? I agree that 10bT is much quieter on HF than 100bT,
Hi Roger, Thanks for your response. I believe the worst of the unwanted interference is generated from within the Zoom DSL router and then radiated from the CAT5 cable that is in between the Zoom DSL
I doubt that is what is happening. You have the basic clock frequencies in the chips generating or regenerating the basic data frame. Typical systems that run Gigabit also run 10 and 100 base-T. Whet
In my experience, the RFI from Ethernet is mostly *not* broad spectrum. (This is distinct from any other hash generated by router processors, etc.) It appears as a set of carrier tones every 62 KHz o
I just got done taking care of my in home ethernet, a number of runs at 10, 100 and 1000 made for alot of noise. Some of the noise can be from poorly made cables. Many cheap jumpers that come with ge
I realize you asked part of this before, but with more information now... If you are going to redo things what about first starting with upgraded routers and switches? Good, routers will run less tha

I've found the same, that 100BaseT is noisy and 10BaseT is quieter. Jim K9YC reported the opposite at some point in the past, but I don't know what his current thinking on that issue is. Here's what
How do you do random length "infrastructure" cabling with fiber? All I see are pre-cut and terminated jumpers for sale. I assume that means that cutting and terminating fiber is a non-trivial operati
Without too many details, I once saw a couple tech pondering over what to do about a broken fiber and no splices. I cut the fiber connected them together using a butt splice, really, and they were ba
Terminating fiber is not easy, but kits and instructions are available. But pre-made assemblies are readily available, for instance this place(randomly picked from google search): http://www.fibercab
Thanks to all for the comments/suggestions. I'm not opposed to buying new hardware - But I hate to buy and find out that doesn't sufficiently remedy the problem. So I'll start off by recabling and se
quite Mike, Before you buy anything, study my RFI tutorial if you haven't already. http://audiosystemsgroup.com/RFI-Ham.pdf The issue of 10MB or 100MB may not be as important as the the mechanisms th
