This web site aims to depict long-term trends in digital amateur radio use, including both effects of ionospheric propagation and human behavior. Each plot shows a measurement of digital radio activity by amateur radio operators: the number of spots recorded per time period, the average distance between sender and receiver for those spots, etc. These are shown "per day" or, more commonly, "per 5-minute interval".
FT8 spots were collected by pskreporter.

- Replace standard deviation with coefficient of variation
- Use distribution density for sequential multi-day plots?
- Replace user interface (with JavaScript? REST API?)
