Yes, exactly, it's not the $20 or $80 solution, it's the $300 solution - keeps noise from the copier from traveling back down the ground circuit. This is not a...
If anything like that happens again, I would think the manufacturer of the device causing so much interference could be asked to fix the problem. Devices that...
I really appreciate everyone's input about this! It's good to know that even a trunk power line wouldn't inherently cause interference. I live a couple of...

We have just has a very good meeting in London. We agreed to make a new version of IEC 60118-4, with no significant technical changes but many clarifications...
I don't doubt that a modern current-drive amp designed for loops is better for loops than a conventional "voltage-drive" amp. However, I have some equipment on...

... Ron, writing that you have less than zero word discrimination reminds me of the discussion we had on Beyond-Hearing years ago after some people wrote the...
Hi John, I used an inductance meter. R = 3.1 Ohms, Inductance = 310 uH For 500 feet, that is .62 uH per foot although the length measurement may not be...
