Chrisgraff,
please keep us posted.
i am truly hoping that it will be solved for you.
again, MASS definitely helps with RFI, but also of course the copper mesh.
Tin is good too, but copper mesh as in microwave shielding works best. scientifically of course.
that is absolutely wonderful that you have a power company that treats you like a human. Very fortunate! Another option is to further test, is to remove the "meter/transponder" and turn OFF other meter transponders for WATER/NATURAL GAS/.
please do post back. best of luck to you my friend

Hi Chris,
Hey, if i remember correctly, didn't we read some low voltage on your ground line as well? I've been studying some alternative power options recently, and in the process, I learned something very interesting. The power company typically grounds their systems using galvanized rods (zinc). You have installed copper rods. Guess what happens when zinc and copper is connected together? It creates what is known as a "battery effect". Essentially you are creating an earth battery and injecting voltage into your ground system possibly as well.
I do like the faraday cage idea though. copper mesh is best, but extremely expensive.
Wow, six years later!
That battery effect is DC and with low impedance power wiring, it's voltage is just about zero.
I received an email that there was a new post on this thread, so I replied. BTW, how is the studio doing? Did you finally get some of the quirks worked out? A lot has changed in 6 years. I've gotten married, and now expecting a little one in December.
Yeah, there was a spammer that spammed a few threads (including this one) before I managed to block him permanently and delete his trash. - Stuart -I received an email that there was a new post on this thread, so I replied.
Hi,
It's probably not much of a help and a bit off topic, but i wanted to share it because it's a good example of things you cannot solve.
I have been quite a few times in a studio in Cologne, and the funny thing is that it is next to the railway. Every time when a train passes by, we hear a hum (pretty loud one) on every channel that has a microphone or a DI attached.. The cause: the switch of the railway has a huge magnetic field because of the power and magnets used in the switch.
The unfortunate thing is, that there is nothing that can fix this problem..
Anyway, I hope that you found a solution!

I recall almost 20 years ago, reading about a studio that had that same problem with electric railroads.
Farady cage? a really BIG one?

that would be an interesting experiment! tho i don't know if it works because we do need microphones in there, which conducts power.Farady cage? a really BIG one?
and the strangest thing is that here it is around 35 meters away..I recall almost 20 years ago, reading about a studio that had that same problem with electric railroads.
You mean wireless mics? That should be no problem. They should still work inside, or outside the room, but not from in to out, or out to in. A Faraday cage blocks electromagnetic signals going in or out, but those that are already in should be fine within. Your cell phone wouldn't work inside either (which might be a blessing in disguise! :) ). - Stuart -that would be an interesting experiment! tho i don't know if it works because we do need microphones in there, which conducts power.
