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?

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...

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...

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...

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??

I am trying to find good web site to learn about how diferant Radiowaves act with the diferant Ionosphere Layers. You know like the D Layer absorbs what FRQ in Daytime and what goes on at night. I find so many diferant web sites but then they all may say something a little diferant...

Can someone tell me about these Ionosphere Layers? How many Miles above the Earth does the D Layer Start? And the same for the E Layer and F1 and F2

I want to make a shortwave ant. I have two Slinkys and the are the big ones. The are both 3 Inch Round So I was going to make a Di Pole ant. out of them and put one Slinky on eatch end and just stratch them out. What I need help with is this? They say that when you take a wire and make a...

I know that Ground Wave or Serface Waves are VLF and LFF Bands. What Bands are Line Of Site or Direct Wave???

I am looking for a good place online to read up on how Radio Waves Propagate. Like Groundwave Skywave Line Of Site Wave. I whent to Wikapedia and Google and all over. And I find a little bit here and a little bit there and everything kind of talks out of both sides of the Mouth...

I just need some help if anyone can give it about the types of Waves that are used. 1. wave is the Ionishperic Wave is when wave bounce back and forth between the Earth and the Ionishper till it gets to the Radio and these wave would be the HF witch is shortwave and MW witch is Mediumwave...

I am a Computer Repair Teck and need some help and I lnow this is for Shortwave Radio but I was thinking that someone maybe can help me. Computer Power Supplys give three Voltages +3.3 Volts and +5 Volts and +12 Volts I get this. Now an ATX Power Supply will have a 20 Pin Malex Connector...

I found a Web Site that shows you how to make a Dipole Antenna without having to cut a Coaxial Cable. It says you will connect the Coaxial Cable Feed Line to an SO239 Plug and that Plug is ware you can atach you two Wire Leads. When I call Radio Shack they tell me that the SO239 Plug has a...

I have a FULL range Shortwave Radio and I would like to get Australia in. I do not know what Meter Band they are on or any of there FREQ. there are on. And what would be a good time for me to try to get them on my Radio. I am in the U.S.A please help. Thanks

I need help findingout the wavelength to get the Length of wire for an ANT. I think it goes like this. 300 Divided by FREQ in MHZ will give you the Wavelength in Meters. So if I wanted to cut an ANT. wire to get the FREQ. 7.05 MHz it will go like this. 300 Divided by 7.05 MHz = 42.55 Meters...

I have called every Radio store and Electronics store and even on the net. I can't find the PL-259 and the SO-239 connectors and every place tells me they don't know what they are. I am going to put the PL-259 on one end of a Coaxle Cable and the PL=259 will connect to the SO-239 connector...
