Free from radio interference, it's one of best high-frequency receiving sites in the world. As early as 1902, a massive 300-foot wooden "spark" tower, for sending and receiving Morse signals, was operating here. Now just its wooden base remains, as well as some original wooden houses, imported from Germany. The radar site is named after Dr. Robert Unwin, an internationally recognized pioneer in ionospheric physics and radar detection of the ionosphere. In 1957 he established an optical station at the Awarua Radio Site, where the current radar is located. The Unwin radar, along with its partner radar at Bruny Island in Tasmania, is run by La Trobe University in Melbourne, Australia. The full name of the project is Tasman International Geospace Environment Radars (TIGER). TIGER in turn is part of an international network of similar high-frequency (HF) radars called SuperDARN (Super Dual Auroral Radar Network). As proof that nations truly can work together when it comes to science, SuperDARN consists of a mini United Nations: the United States, Canada, Australia, New Zealand, Great Britain, Iceland, Norway, Sweden, Italy, Japan and South Africa. The TIGER Unwin station is one of 18 similar stations - eleven in the northern hemisphere, and seven in the southern hemisphere. Some are based in the United States and Canada, some in Iceland and Scandinavia; in the southern hemisphere, in Australia, New Zealand, South Africa and Antarctica itself. Further ones in Siberia, northern China and Antarctica are anticipated. All are targeting their beams towards the Polar latitudes. Together, they are measuring an area roughly equivalent to a fourth of the Earth's surface.

Might as well add Svarbard to your list.
This report describes the deployment of a new ionospheric sounder, the Digisonde Portable Sounder (DPS), at Svalbard (78.2 deg N) and discusses the first results obtained with this instrument. The most important new feature in the DPS, not available in the old Digisondes, is the capability of high precision incidence angle measurements and spectral characterization at up to 128 ranges.
This capability can be applied to identify and track irregularities generated by high power HF transmitters as planned for HAARP (HF Active Auroral Research Program) experiments in Alaska.
I don't understand the need to transmit signals using the ionosphere.
It seems satellite would be much easier.
I have seen where these are supposed to modify the ionosphere, causing me to believe this is about weather control.
These discoveries [Immel et al., 2006] show that the entire ionosphere, sometimes referred to as “the inner edge of space,” regularly responds to the tropospheric weather systems below. The likely mechanism for effectively carrying tropospheric energy upward to the edge of space to modify the ionosphere is the generation and upward propagation of large-scale waves, known as atmospheric tides.
