Hi Pat,
That is a great idea. I participated , along with Greg VE6GRT in the WWV centennial event run by the same group. It is an interesting exercise and gives an opportunity to contribute to a growing citizen science project.
I was using my own Flexradio 5000a to make the measurements, and I think it would be a good project for the club Flexradio.
I understand that the new tuner is delivered to the club, so the opportunity to get the Flex in action and to use it in this project is there.
I am sure willing to have a go at this, anyone wanting to join, please let me know.
