VLF Whistler Receiver Natural Radio Sensor Hear The NaturalRadio Sounds of Earth

Description

VLF Whistler Receiver Natural Radio Sensor Hear The Natural Radio Sounds of Earth.
This sensor detects the odd and beautiful electrial sferic waves that the earth makes in the range of 30 Hz to 10 KHz.
These waves come from lightning and geomagnetic activity and from near-space.
Whistlers are lightning flash energy that gets ducted into magnetopheric waveguides in the ionosphere. You can hear these rare 1 to 2 second long strange whistling tones made by the earth with this receiver.
More common are the beautiful sounding Tweeks, which are similar to whistlers but are of very short duration, about a 10th of a second, instead of several seconds.
Strange sounding waves from space can be heard, such as Dawn Chourus, which sounds like birds chirping at local time just before sunrise.
You will need to listen away from power lines, as man-made electrical fields can be heard as a buzzing hum.
Insects such as bees can be detected from their buzzing electrical field around their wings.
Hummingbirds can also be detected with their humming wings electrical fields.
The -constant- background crackling sounds day or night you can hear with this receiver are powerful global lightning strikes.
Has two wire connections for any 1.5 volt battery (you can use "AAA", "AA", "C", or a "D" battery type.) and supplied with audio output RCA type cable.
Reverse polarity protected, overload protected, static protected.
MADE IN USA.
