EMF test for TV's and monitors ------- Star Wars themed

Sometimes other sources make it hard to distinguish what a monitor is emitting. This video can in some cases make it easier and it's a fun experiment to show to your friends. instructions:
.
STEP 1) Know how to use a simple handheld radio that is suitable for this job (some radio's are better than other and some have noise cancelling, which is something you don't want).
If you are new to this, watch the following video first and read the short but
detailed instructions at the end of the video to learn how to use a radio:

.
STEP 2) Sometimes it works best when you make this video full-screen, sometimes it works best not full screen. I recommend activating loop (right click on the video) if you have a plasma TV e.g. and plan on going outside to see how far the TV emits.
.
STEP 3) Watching the flicker doesn't bother me (and shouldn't bother most people), but if you think you are sensitive to light flicker, place a piece of cardboard or something in front of your screen.
Even when i place a large piece of thick aluminium foil in front of my monitor i can hear the radiation. Also I hear it when measuring my monitor or TV in another room through a wall.
.
If it doesn't work:
A) Go closer to the screen or monitor with the radio.
B) Often you must turn the dial on your radio to receive static on a different frequency before it starts working (and double check if the radio is set to AM).
C) If it still doesn't work, try the same on a different TV or monitor. It doesn't always work well on every screen for some reason.
D) Try full screen and not full screen, sometimes not full screen works better for some reason.

I based the rhythm on this song:
"The Imperial March (Darth Vader's Theme)"
I increased the tempo a bit, because I thought this to be more practical since it's a bit easier to hear the pattern. If you would want to match the tempo to the song, you can use an extension like "Video Speed Manager":

Have fun ;-)

I use to think this could be useful to buy new equipment and test a specific screen with this video on YouTube or on a USB stick together with a radio with headphones, but nowadays I think it's much better to buy equipment by testing it with a Gigahertz ME3851a or ME3951A.
