Nothing heard over the last pass over US, so it looks like that EIRSAT-1 has been re-entered.

what metric is in right bar, 200-700 ?

That is a good question I never before considered asking, maybe @cgbsat can answer the question?

Looking at a rfplot output: what metric is in right bar, 200-700 ?

Those are the channel numbers.

Just as at the top are the spectral numbers.
