I think it might be possible to ingest RBN data and display a moving average of CW speed on the map. I’m not sure this is actually useful! Back-burner sort of thing for sure.
Is there a spots feed for POTA, or are the various things I see that reflect POTA spots just scraping the spots page over and over?
I use https://api.pota.app/v1/spots for the POTAmap.
