Abstract | The Weak Signal Propagation Reporter (WSPR) is potentially a useful tool in the quantitative study of ionospheric propagation. But there are a number of factors to be considered in the use of WSPR to make propagation measurements, and it is useful to have a baseline at solar minimum to compare with measurements as we approach solar maximum in the next five years. One key measurement question is to what degree WSPR is linear, and over what dynamic range, in real-world propagation conditions. Another important issue is the role of noise in WSPR measurements. WSPR spots report SNR, not signal strength, so identification and quantification of various sources of noise is necessary. During a year of analysis of spots of my transmissions on 20 meters from a mid-latitude location (Virginia Beach), I have addressed these questions and made other observations of propagation at solar minimum. My results include:
