What is it?

An Angular web app for analysing WSPR propagation data, to determine (on average) the best time of day and frequency to work either the most countries, or the furthest distance.



The web app is a spring-boot application deployed to Google’s app engine. This allows for the app to be scaled with demand, and allows for scaling to 0 if the app isn’t used for a period of time. The WSPR data is stored in BigQuery, whose hosting costs are generously supported by Graham Polley. The data is manually updated from wsprnet, once a month (when I remember) in which a number of other statistics are calculated.
