Hi All

This week my daughter Erin has been learning about the doppler effect.

To demonstrate the effect in practice we listened to the ARISS UHF QSO between Astronaut Thomas Pesquet and Collège André Malraux, Chatelaillon-Plage, France, via F4KJT

We were also able to watch HamTV live via the BATC stream.

437.535 MHz +- 10 KHz Doppler. We made a video of our doppler observations.
