Currently we are at the nadir of the sunspot cycle, so HF activity above 20 meters is limited.
But, amateur radio is not dead. The average age of an amateur operator is probably over 60, but there is still a stream of young people getting into the hobby.
For me, the most interesting current activity is digital messaging on HF. There is a mode called JT8, which is based upon work done by Joe Taylor, a Noble prize winner in physics. It allows for reception of very low level signals.
FT8 allows low power transmission with compromised antennas, which makes it popular with an aging demographics living in deed restricted communities. I run about 30 watts to a “distorted” dipole in my attic. Not as good as the antenna at 100 feet and a kilowatt at my club, but it works…
