Hi, since I am a licensed radio amateur the radio wave propagation is of great interest to me.
There are several existing realtime maps that it may be possible to extract data from:
Pskreporter: https://pskreporter.info/
It needs the Maidenhead locator to display the received stations in that location.
The four first signs is sufficient.
For me it is still not clear what you would like to achieve.
E.g. what is the input for your query and what would you like to extract from the output.
The psk-freq.pl CGI script e.g. could be queried by using a curl, wget script or the http binding. The output can be parsed by a script. But it looks like you are not allowed to execute that CGI script that often.
