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...

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...

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?

thanks but Ok so the D Layer at Night lets FR thought so it can reflect of the other layers. But at Night the other Layers loss there Ionization right? So how can they reflect anything?

thank but Thanks I get it now all RF waves Radio FREQ. will be Absorbed by the D Layer in the Daytime because the D Layer is More Ionoized. And at Nighttime the D Layer is Less Ionized so RF go right through it and gets to the other Layers so it can reflect off them. But one thing? If...

thanks but So I think I get it now? At night the D Layer is Less Ionized so HF that would be High FREQ. Shortwave will be Absorbed and not reflected. And LF that is Low FREQ. will pass right through it and be reflected off another Layer that is More Ionized?????????

thanks but So if I get what you are telling me? At night the D Layer is Less Ionized so Shortwave will be Absorbed by it and not Reflected back to Earth??????????????????? So would I be right that just HF get absorbed by the D Layer or does it afected more??

Someone here told me before that the D Layer of the Ionashpere will let AM Radio Waves pass through it. If AM Radio Waves Pass through it then how does Shortwave Radio work at all??? Is it because even if the D Layer lets the AM Radio Waves throught they still will hit the other Layers and...

Thanks but what about the stratasphere mesophere troposphere???????

The D layer is the lowest layer near the Earth. Is there any FREQ that come back down from it or is it just the other Layers that reflect the Radio Waves back down??

Am I right that Groundwave is any Radio Wave below 3. MHz?????????????? I whent to wikapedia and put groundwave in. And I did not get anything about Radio Waves

What would be a good web site for information about how the diferant radio waves travel and what Ionashpere layers reflact and how they work?? I did go to Wikapedia but I did not get the info I wanted about the FREQ and Ionosphere layers and how they work time of day things like...

ok I think I get it so if I see a wavelength of 10 km it meens ten kilometer band and if I see 10 m it meens ten meter band?

what I ment was this km wavelength is kilometter but wen you just see m like 10 m what is this meen

Can someone help with what this meens? Wavelengths km and cm I get this then I saw just m what is this

I was looking all over the net and found groubnd waves are 30 kh to 3,000 kh And LF and VHF and HF are ground waves. But VHF is line of site I thought?? I went to wikapedia but I get more confused. So let me ask this way? I know at low freq it is groundwaves and as...

thanks but so would I be right that sertaine FREQ. are for line of site and the same goes for Groundwave to?????????????????

thanks but Well what I meen is Ground Waves move along the Earth serface they do not go into the Ionosphere right????? so sertan FREQ are just shortwave they will never be groundwave they just go to the Ionoshpere. Line Of site waves will never be ground waves they just go straight...

thanks but so if it is wave length depended then why is uhf and vhf line of site??? Thoso are bands????????????????

If vhf and uhf are line of site waves they go in a straight line from the transmitter. Then ground wave go along the Earth Serface I get this. But is AM ground wave and FM line of site??
