Plot WSPR data on a map
The Weak Signal Propagation Reporter Network (WSPR) is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions.
This flow plots the contents of an ALL_WSPR.TXT log file on a map. This is a log of all WSPR spots logged by your local computer/radio.
There are mapping tools online, but this flow creates a map locally.
This flow expects to connect to a network service on the WSPR server and retrieve the ALL_WSPR.TXT log file in CSV format.
In my example I configured inetd on my Raspberry Pi WSPR server to listen for a connection and then forward the output of the following command:
tr -s '[:blank:]' ',' < /home/pi/.local/share/WSJT-X/ALL_WSPR.TXT
But all this is doing is collecting a CSV file to feed to the next node. There are probably better ways to do this...
