Forum Description:
People ask, “I’ve heard of WSPR, but what is it good for?” This session explores the origins and basic characteristics of the WSPR (Weak Signal Propagation and Reporting) protocol and how amateur operators can use this for different applications in their shack and even for remote operations. We will explore the numerous ways you can send and receive WSPR signals and use this information to assess near-real-time propagation, test and compare antennas, observe the effects of day and night propagation, and confirm the effects of space weather. Some advanced applications will also be mentioned for using WSPR in ionospheric research and for amateur balloon launches and tracking. Finally, we will look at kits and ways to homebrew your personal WSPR systems.
