Feature Request - Log Costas Loop Frequency output with each decoded packet.
A possible addition to the various demod flowgraphs (mainly the 9k6 FSK one at the moment) - the ability to log the exact frequency of each packet.
It looks like the second output of the Costas Loop block may provide this information. If this could be logged alongside the decoded packet somehow (this may be more an addition to the new observation artifacts that something that can be accomplished right now), that would be very useful to help fit TLEs to observations.
Not sure how useful the output is - would probably be worth doing some testing to see if the data is of any use to start with.
