@Memoryman,

Not from inside a Faraday shield!

An open basting tray is not an effective Faraday shield.

@MarkE,

It's enough just to show that the LEDS don't dim down from it.

Are you trying to say that if one places a circuit in something that is not a Faraday cage that we should be amazed that the circuit still acts like RF energy impinges on it, just because:  well ... RF energy still impinges on the circuit?

Do you know how a Faraday cage works?  It is our old friends Faraday induction and Lenz's Law at work again.  A changing magnetic field impinges on a conducting surface inducing currents in that surface that create an opposing magnetic field:  an image.  The better the conductor, the more exact the image is and the closer the sum of the image and the impinging field is to zero.  You might note that the top of the basting pan seen in the video is open.  there is no metal there to circulate current and so create an image to cancel the impinging field.  Placing a big conductive plate beneath a vertical antenna is common method of constructing an efficient 1/4 wave dipole.

@MarkE,

Golly, you sure sound smart.

It doesn't matter whether you think I know what I am talking about or not.  What matters are facts that you can verify.
