Thinking some more, Mastodon seems to support a pretty robust API:
https://docs.joinmastodon.org/api/guidelines/
Maybe it would be feasible to start putting together a set of standard hashtags to write a simple viewer/spotter against with the API?
#POTA #SOTA #WWFF #SSB #CW #FT8 #OTHERMODE #20M #10M #PARK_US_2299
etc.
Kinda clunky, but it would be easier than spinning up a full new federated app, and wouldn’t have the side effect of potentially fracturing the community…
My vaguely similar plans involve a DIY Yagi - premade antennas are expensive. I’m planning on focusing on hydrogen line though, so I’m honestly not sure how wideband they get.
