When I first decided to build this loop, it was only a day prior to a trip to the South Carolina coast where I planned to do a little DXing. I didn’t have all of the components, so I popped by to see my buddy Valdo (N3CZ). Vlado, fortunately, had all of the components and ...
The material I chose to build the j-pole antenna was 3/4 inch copper pipe used for plumbing. Here are the plans to build a 2 meter J-pole antenna: The above dimensions for the J-pole are in inches. Measurements on overall length, and stub length are from the centerline of the separa...
Find an AM radio and tune it to an area of the dial where you hear static. Now hold the battery near the antenna and quickly tap the two terminals of the battery with the coin (so that you connect them together for an instant). You will hear a crackle in the radio that is caused...
15 surprising ways I used AI to save me weeks of work in 2024 If your Windows 10 PC can't be upgraded, you have 5 options before time runs out I test wearable tech for a living. These are my favorite products of 2024 Editorial standards...
As it continues to be pushed by sunlight, the solar sail-propelled vehicle will build up speeds that rocket powered vehicles would never be able to achieve. Such a vehicle would eventually travel at about 56 mi/sec (90 km/sec), which would be more than 200,000 mph (324,000 kph). Tha...
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...
There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this par
A radio receiver is just the reverse of the transmitter: It picks up electromagnetic waves with an antenna and converts them back into an electrical current. At its heart, radio is just the transmission of electromagnetic waves through space. Radar is the use of radio waves to detect and mon...
automating the process.If you don't want to build a jammer yourself, you can use another car key working on the same frequency to disturb the signal, or even an HAM radio (but the transmission power in this case would be an overkill and would probably render impossible any sniffing effort...
