[TangerineSDR] 04/19/2022 Whistler Events!!

[Dr. Nathaniel A. Frissell Ph.D.]

Hey, Jonathan! This is really great! Thank you!

I was on a journal club telecon with people from the NASA MSFC yesterday re-capping the HamSCI workshop, and your work came up quite a bit. They really liked it!

I'm looking forward to the results now that we have the grounding noise issue resolved.

One of the allure of whistlers is actually listening to them! Attached are movies I've made of the spectrograms and the event audio.
