A communication radio-frequency module is provided that has a semiconductor device to which an antenna element is connected. This communication radio-frequency module includes: a supporting body that has a waveguide formed therein; a wiring board that is fixed onto a surface of the supporting body...
As in radioamateur hobby we will start with the most important part first: Antenna. It is important to use an antenna which has optimal match for the frequency you are going to use it. So forget the dvb-t antenna which comes within the RTLSDR stick and concentrate on making a better an...

Here I is the moment of inertia of a NS, 𝜔=2𝜋/𝑃ω=2π/P—spin frequency, 𝜇μ—magnetic moment, and c—the speed of light. Such measurements might help us to understand the origin of the source. Short spin periods will definitely point towards young ages of the magnetars, ...
The three-inch LCD screen is bright and easy to read as it displays your channel frequency and other settings. The keypad on the microphone allows you to enter one of the 200 channels and adjust the frequency as needed. Note that while the product description on Walmart states that you do...
