    1. Radio Astronomy in School

    2. Electromagnetic spectrum

    3. Atmospheric electromagnetic opacity

    5. is a non-profit scientific, educational corporation, founded in 1989 by a team of NASA employees investigation of very low frequency (VLF = 0 Hz to over 100 kHz) radio signals in the earth's magnetosphere These signals are both manmade and naturally occurring (most of which originate from lightning) Interactive NASA Space Physics Ionosphere Radio Experiments"

    6. INSPIRE VLF3 receiver kit Field observation setup: INSPIRE VLF3 receiver with stereo cable Portable cassette tape recorder with headphones Whip antenna Ground stake

    8. Radio Meteor Observation meteoroids disintegrate at an altitude of 80 to 130 km the trails they leave behind are full of ionized gases that reflect radio waves distant VHF(30MHz-300MHz) radio signals can bounce off the meteor trail (forward scattering method) can monitor meteor activity regardless the weather conditions and at daytime

    9. Radio detection of meteors

    10. Radio Meteor Observation Experimental setup

    14. is an education project to build and distribute inexpensive ionospheric monitors to students around the world the monitors detect solar flares and other ionospheric disturbances Earth's ionosphere reacts strongly to the intense x-ray and ultraviolet radiation released by the Sun during a solar event the signal strength from a distant VLF transmitter, reflected by ionosphere, will follow this changes

    15. Super SID Receiver - simple and low-cost “wire-loop antenna”

    17. NASA Radio Jove Project was conceived in 1997 by a team headed by Jim Thieman at Goddard Space Flight Center sold its first receiver kit 1999 (10th anniversary – almost 1400 kits sold) observe and analyze natural radio emissions of Jupiter (bursts), the Sun (Solar flares), and our galaxy (transit)

    18. Frequency of operation 20.1 MHz Receiver type: direct conversion (a hamradio transceiver can be used – expensive) Antenna: dipol ?/2 or phased dipol or multi-element

    20. Radio Jove at ATLANTYKRON Summer Academy 2005 50th anniversary of the discovery of Jupiter's natural radio emissions
