just move the MUF up higher. More sunspots "enable" higher bands.
Propagation over the world is just as good if your ERP, local noise, and
antennas are about the same on low bands as higher bands.
Sky noise (galactic synchrotron) is inversely proportional to somewhat
over the square of frequency and ERP for a given amount of real estate
and input power increases with frequency. There may also be ionospheric
and surface reflection effects.
