New setup, all obs are solid purple

I have a Pi 3, setup with the satnogs image. Configured details and its showing as online. I can receive commercial radio with the V antenna set at the correct length but all my observations are coming up blank.

This is the kit I have:

Any suggestions welcome.

Thank you

Please link to one of the observations.

Having said that, when I get a “purple” waterfall - I reboot my station (sudo reboot), and that seems to solve the issue (for me). I’m sure you’ve already tried that, but if not - give it a whirl.
