Re: Question about video-signal adapters (HDMI-to-DVI, etc.) [LAPTOPS]

With a HF59B, you cannot measuere the *dirty air* this Macbook is emitting.

Yes, of course the WiFry is disabled. That's a given.
I measured this MacBook Pro with an Gigahertz Solutions HF59B
and it had no measurable RF.

1 meter is not nearly enough distance - I still feel this thing at 3 meters
or more. The headache and tinnitus are atrocious. But many here
watch TV - quite an amazing feat for an electro sensitive.

I found that Sun's keyboards tend to be slightly better on EMF than Dell's keyboards. However, with both, it's only when I'm typing that I measure the EMF. (In contrast to laptops where the EMF is quite continual). Keyboard EMF is maybe ~ 1mG -- much lower than the laptop? Mechanical mouse is better than optical mouse, which is better than wireless mouse.

I presume you say that, Charles, is because most of the "dirt" emitted
by this laptop are low frequencies. The SPECTRAN NF-5035 picked
up frequencies all across the spectrum, peaking at < 300 Hz.

Hello Eli,

when you mount a probe on the SMA bus, you will find a lot of frequencies in the kHz and even the lower MHz range.
