Can anyone give a good site that will tell what time of day eatch Layer will reflacted what type of FREQ??

I know that say Daytime almost everything gets absorbed by the D Layer. But I want to know about the other layers.

I go to Wikapedia but they give way to mutch info?

I don't think it's possible to predict what you are wanting with any accuracy, it's always an "if this, then that" sort of thing. If it were possible, I have to think that it would have been publicized and been well known by now. I figure it's about as accurate as weather forecasting was 10 - 20 years ago, more guessing than anything definite.
I honestly hope I'm mistaken and that there's a reliable propagation site! I'd love to know where to look also. The 'levels' and 'indexes' are publicized in a number of places, and they let -you- do the 'predicting'/guessing...

I like this gadget, it has an opinion on HF Propagation.
Windows Live Gallery

The Data is sourced from here:
HF Propagation and Solar-Terrestrial Data Website

Finally, you can overload your Propagation senses here:
SOLARCYCLE 24.com / Solar Cycle 24 / Spaceweather / Amateur Radio VHF Aurora Website

HF prediction is still a bit of an inexact science. Probably one of the most used programs for this is VOACap which has an online interface, VOACAP Online.
