@akkermei @jerabaul29 : I've started experimenting with the starnote. I was planning to send the 20 min spectrum including position. Maybe send every hour, but send 3 spectrum (20 minutes), depends on how good resolution is needed for the spectrum. The data-limit for one message is 256 bytes (minimum 50).

Nice! I follow their website now and then, very exciting to see them (and the skylo network behind them) growing! Still looks like coverage is mostly land in US / EU / Southeast Asia + some coastal area? Will be exciting to see when / how fast they expand to truly global coverage :) .

Yes, I hope it will give us expanded range along the coast and in the North Sea. Doesn't look like it will work for the Arctic (except south of Svalbard).

This would also be a place to add other metrics for the better spectrum. For this project it would be very nice with stats of breakers. I am thinking maybe to do that by looking at each segment of the welch spectrum, and count peaks.

More stats, like breakers?
