Hi Robert,Thanks for the tips,
There are definitely a few things I might do differently, given a second chance (or next occasion).
Per your notes: I did smooth out the data, and will present that chart, as it does give a clearer picture of the (expected) slower moving change associated with the eclipse event. Receiver was not GPS locked, but the method I used for collection and analysis within Spectrum Lab should have been robust against a small amount of drift. It recorded whatever the maximum signal in a small band ~ 200 Hz wide. An average noise value was subtracted, using another selection just a few hundred Hz away. The Receiver is known to be sufficiently stable for this setup, and had been powered up and allowed to stabilise for a couple of hours ahead of the data collection.
What I did not bargain for was a second signal that seemed to appear in my passband. I think this led to some of the oddities in the chart. Not certain of the origin of that signal, but I do still have the screenshots from the Eclipse day.
Would have loved to cast the net a bit wider for other signal changes at different frequencies, but I was occupied with the enjoyment of watching the eclipse!
