You can see them very easily at dusk. It’s dark enough but they are still in sunlight making them very clearly visible. There is always one or more easily visible (by design).

There's more like 30 always visible...

The 1 I suspect is some other satellite

Visible in RF. That doesn't mean literally visible. They few that are seen are those still in sunlight when the observer is not.
