They do according to the papers bitmain posted on the S5 post the other day .

I personally don't doubt that they do. I have used a few mobile HAM radios, and one big scanner. No issues and I have decent amount of miners and have had zero issues.

If you go right up to anything with lot's of electricity it will cause interference right around it. But again you turn up squelch if for some reason you feel you need to transmit with your head right next to a miner.

Do AntMiners comply with Part 15 of the U.S. Federal Communication Commission's rules and regulations?

Implicit in my question is what percentage of watts going into an AntMiner get converted to RF interference. If it's a lot, it could be a safety issue, especially since the cases of many AntMiners (e.g., S5s) are open and thus do not act as Faraday cages.

Good question. Wish I still had my meter from the cable company. I'm sure it's not noticeable. But that would explain all of Boeings planes falling out of the sky by my house. Grin

I do have a amateur radio license and I am able to go on many freq's and have never had trouble with interference from asics.

Me, too
I tuned to 350 MHz on my radio, the freq at which my S5s are operating, and I heard quit a lot of interference (squelch had to be set above 10 on my Yaesu handheld just to silence it). I changed the freq of the AntMiner, tuned to 350 MHz again, and didn't hear anything. I tuned to the miner's new frequency and heard the same noise. Certainly the S5s, not being in completely enclosed cases / Faraday cages, emit more RF interference than enclosed miners, but it doesn't seem to be much, considering my power levels decrease fairly rapidly with increasing distance my handheld Yaesu is from the miners.

I would guess it is to do with the electricity as much as anything your talking about a decent amount of watts. And it would create a electric field that farther you get away less it is. I cant think of the device name but I have one where I can see if electric is flowing through a cable just by the air around it because of the electric field.

Go by something else with 550-600 watts of electricity and I think you will see a small amount of interference no matter what it is. If you really want interference look at a electric drill going along antenna wire, or run near a microwave.

A current transformer... They are used every where!

let me tell you how much a Chinese manufacture cares about Merican regulations. 0, zero %.

About as much as they do with some of the class c fireworks that I have seen which if handled wrong could easily blow a part of your body off.

I have a decent amount of Bitmain and other gear. I don't think any of my asics would have trouble complying with this.

UPDATE: Answer: Yes, they do. Their sales page says "Certified By: FCC / CE."
