  • How do disturbances such as solar flares, geomagnetic storms, and traveling ionospheric disturbances affect radio wave propagation?
  • How does ionospheric science help amateur radio operators improve communications?
  • How can I use my existing radio equipment for science initiatives?
  • Have fun in a friendly HF competition. And there are other experiments as well!

Who: Volunteer amateur radio operators, short wave listeners and science researchers from multiple US universities.

The SEQP is conducted by HamSCI –The Ham Radio Science Citizen Investigation — HamSCI serves as a means for fostering collaborations between professional researchers and amateur radio operators. It assists in developing and maintaining standards and agreements between all people and organizations involved.
