Here is yet another specialized instrument being applied to the task. This time, a portable magnetic and electric field meter. This is one sensitive device. To give you an idea, when put in magnetic field mode, and just holding it in my hand, the meter dances with the changing magnetic field to the tune of music coming out of my speakers!
I tested the Entreq using the RF mode while it is connected to my main audio system. Connectivity is through an RCA jack in the AUX input of my pre-amp, with the other end being a 3.5 mm headphone jack that is then connected across the back of Entreq. Here is the output of that:
So we clearly have Electric field radiation. Disconnecting the cable to Entreq caused the meter to go to zero so clearly the source is from the pre-amp, not stray field:
To see if this radiation is the special property of the material inside Entreq or the bare wire within, I hooked up a piece of wire to the headphone jack:
As you can see, the same radiation exists with just that wire (I could have wiggled the wire enough to create similar field strength to Entreq so don't worry about that).
I reconnected the connection to my pre-amp to the Entreq and moved the meter around to see where the active elements are inside the Entreq:
This is the top of it (the front of my meter is where its sensor is so had to put it upside down).
So the conductive element/wire inside Entreq as Bob's picture found, goes all around the box.
In summary, coming from a very different direction, we yet again confirmed what we have here. That is, a piece of wire coming from our audio equipment, radiating low level energy. No "sinking" or "shunting" or "absorbing" is happening. But the opposite.
