Description

The VLF-N-2 very low frequency radio receiver is an excellent choice for detecting a wide range of unusual sounding naturally occurring radio waves. Discover the strange frequencies that the Earth and magnetosphere produces! Wideband, no tuning required, it pulls in the whole VLF band without demodulating it. Made in USA. The VLF-N-2 is the next generation in VLF radio receiver technology in our electric field sensing category. New negative ground low noise technology. (Our VLF-N-1 is positive ground. The new VLF-N-2 is negative ground). It allows you to listen in on the very lowest radio frequencies possible called the Baseband. There is a wide variety of natural earth-produced and space-produced radio emissions in this band. It can detect whistler emissions, tweeks, and temporally reversed effects, as well as magnetosphere emissions, dawn chorus and global lightning static. It is suitable for use with tape recorders, portable audio recorders and audio amplifiers. It operates on a wide voltage range of 0.7 volts to 12 volts DC and has a low power draw, making it efficient and reliable. The unit comes equipped with a built-in super-range omnidirectional antenna and is camera tripod mountable for easy setup and convenience. Does NOT need to be mounted high up. Just mount it 5 feet above ground by using a standard camera tripod is all you need for extremely long range. Detects tweeks and whistlers loudly at just 5 just feet above ground! Do tornadoes produce VLF audio tonal emissions? If so, this is the receiver to use to investigate scientifically. Any vibration of electrical charges in the atmosphere can be detected with this unit, down to 20 Hz and up to 20 Khz. This receiver has a filter that rejects above 20 kHz and a power output of less than 10 milliwatts. It is compatible with microphone or line level audio inputs and has RCA audio output and comes with mic adapter plugs to fit various audio recording equipment. Waterproof. Weatherproof. This VLF Radio Receiver is a portable and camera tripod mountable device, perfect for detecting a range of natural earth radio wave emissions. It has a wideband receiver with a detection frequency range of 20 Hz to 20 KHz, making it compatible with tape recorders, audio amplifiers, and other audio recording equipment. The receiver has a long-range antenna built-in and is omnidirectional, allowing it to detect whistler emissions, tweeks, and dawn choirus, temporally reversed effects and magnetosphere emissions. The device has a low power draw and operates on 0.7 volts to 12 volts of operating voltage. It has an analog system and has less than 10 milliwatts of power. The VLF-N-2 manufactured in the United States in 2024 and has a single RCA output cable. This VLF radio receiver is a powerful and versatile device that is designed to detect a wide range of VLF radio frequencies. With a frequency range between 20 Hz and 20 KHz, it is compatible with a variety of audio recording equipment, including tape recorders, audio recording equipment and audio amplifiers. It features a built-in long-range antenna, which makes it ideal for detecting weak whistler emissions, tweeks, and magnetosphere emissions. This wideband receiver is easy to operate and has a low power draw, making it perfect for portable use. It has a filter that rejects frequencies above 20 KHz and is capable of detecting temporally reversed effects and dawn chorus. The VLF-N-2 model is made in the United States and has a power output of less than 10 milliwatts. Wide power supply range allows you to power it with any voltage between 1 volt to 12 volts. 3 to 6 volts is recommended. Ships UPS ground in a 36 inch long box. Made in USA
