Alastair Barber Home About A Teensy/Arduino AD9834 Based WSPR Transmitter 29 December, 2021 The Weak Signal Propagation Reporting (WSPR) protocol is designed to allow for radio propagation conditions to be measured across different frequencies and times. It is a slow speed digital mode, and there exists a network of thousands of receiving stations worldwide reporting the identity of received stations, along with their locations, to a central server. Whilst there are applications of this in the field of propagation condition reporting, the fact that there are many receivers always available and logging received signals in real-time, and that the protocol is slow speed and simple to implement, coupled with the fact that signals can typically propagate huge distances, makes this an exciting protocol to build your own transmitters for and see impressive results immediately. The map above shows the stations receiving a single message sent on a December evening from the North East of |
