radio propagation characteristics.

[KD2GOE]

i am looking for information on radio propagation characteristics in the amateur radio HF bands. from 160 to 10 meters how they function over the year and how they act over a 24hr pried.
i know this is relevant to the suns solar cycle but it seems certain bands are easier to work at different times of the year and times of the day.

certain bands at different times of the year has to do with length of the days in both hemispheres.

A lot of information on the net google is your best bet,

Then you can pick and choose what information you want to research.
