As everybody knows propagation on radio waves depends on sunspot numbers. Now (2017) we are going to sunspot minimum which is expected in 2020. Then we expect improving of propagation (especially on higher bands – 20m and above).
Next maximum of propagation probably will be first reached in about 2023. As usual maximum should be with two peaks separated by small deep. See following picture of last cycles and imagine future propagation yourself.
For 160m propagation try to check: DST
