Maybe there is hope for Solar Minimum and HF propagation?
Shall we take up a donation for CubeSats ;)
CubeSats carrying ionized gas could create radio-reflecting plasma. This would occur in the ionosphere, which becomes denser at night.
Bouncing signals between ground and ionosphere can improve range

A fleet of tiny satellites could one day be used to detonate plasma bombs in Earth’s upper atmosphere to improve the range of radio communications.
The US Air Force has granted contracts to three research teams to develop the technology needed to do this, with hopes that CubeSats could carry massive amounts of ionized gas to the ionosphere to create radio-reflecting plasma.
The ionosphere begins roughly 40 miles above the surface and becomes denser with charged particles at night, allowing signals to travel much farther.
