D Layer absorption

[biferi]

I have bean looking at a lot of information about how the diferant Layers work in the Ionisphere.

And I thought I would go step by step and start bottum up.

The D Layer is Greatest at Midday and smallest at Nighttime. So the absoption is greatest on HF at Midday.
How can this be if it is High Charged at Midday would that not refrect waves back?

I see a wide open discussion brewing here, ought to be interesting.

As to your question, depends on what frequency you are wanting to work.

thanks but

Well I do know that diferant FREQ. are going to act diferantly with say the D Layer.

But as for what I read about it it says HF signales get absorbed by the D Layer.

And the D Layer is highly charged at Midday and absorbs HF.

And I thought if it is Highly charged at Midday it sould refract HF not absorb it you need a high charg to refrect am I right?

How many times is this exact same topic going to be brought up? I only ask this because no less than three other occasions you asked this exact same question and got perfectly good answers and still get it wrong. The D layer does NOT absorb all HF signals perse. It DOES absorb (attenuate) lower frequency signals that do not have the energy required to penetrate the D layer. Higher frequency, more energetic signals WILL penetrate the D layer.
