A radio wave is an electromagnetic wave propagated by an antenna. Radio waves have different frequencies, and by tuning a radio receiver to a specific frequency you can pick up a specific signal. In the United States, the FCC (Federal Communications Commission) decides who is able to use whic...
In my example, I am going to make a simple one but you may want to make a more elaborate one. The more elaborate the better. I will use a spool of 18 Gauge solid core wire to make a antenna as an example but you could go as far as to etch your own circuit boards for aesthetic...
A crystal earphone: This simple precursor to earbuds connects directly to the antenna diode. To make the process easier, some kits are also available online containing most of the necessary parts in the box. The Home Science Tools crystal radio kit also comes with an electric amplifier, making...
To make a rough estimate, we can determine Earth's circumference by multiplying its diameter by pi (3.1416). The diameter of Earth is approximately 7,926 miles (12,753 kilometers). Multiplying by pi yields a circumference of something like 24,900 miles (40,065 kilometers). To travel ...
To make a solid connection, tin both sides of the center conductor. Next, attach the other end of the balun leads to each portion of the center conductor, as seen below: Update:Note in the loop diagram near the top of the page that the ground wire on the output connector connects to ...
When the receiver receives the radio bursts from the transmitter, it sends the signal to a filter that blocks out any signals picked up by the antenna other than 27.9 MHz. The remaining signal is converted back into an electrical pulse sequence. The pulse sequence is sent to the IC in the...
Ham radio is used to contact the outside world with surprising numbers of people. Many times has come to the rescue in crises such as natural disasters in which all other communication methods have failed. If you're interested in becoming a ham user, it is a great way to make new friend...
The above dimensions for the J-pole are in inches. Measurements on overall length, and stub length are from the centerline of the separation pipe (horizontal) to the top of the antenna. The Connect at measurement is 2 1/4 inches from the top of the horiz
. Combined with anexternal WiFi Antenna and signal amplifierto increase your range, this may be a great option for those who are close enough to pull in the WiFi signal. As time goes on this may be one of the most reliable options for those that need to stay connected. ...
