Do a Google search for "Ionospheric Sounders". There are hundreds of them operating 24/7 worldwide .... far more than the handful of OTR's. The NBS operates one within the city of Boulder, for example.
There's a network of HF wave-study radars along the US west coast ... some are in the rest room buildings of Oregon State Parks.
