It works a treat. And, yes, folks…it’s fun to build. There are a number of loop designs out there, and to distinguish this one, I’m going to henceforth refer to this loop as in the title above: theNoise-Cancelling Passive Loop (NCPL)antenna. Before we start building, a little ...
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 demodulated audio signal that the shortwave band receiver generates is displayed with an oscilloscope the vertical sync pulses can be seen. With the tested CCD camera it was even possible to estimate the distribution of luminance across the picture based on the displayed wave form. Partly...

The mast was tied to the bench and the antenna was raised. Besides the comfort, the possibility to tie a mast to it is the second reason why I am always looking for benches. The conditions were far from being perfect, and it took me 40 minutes to get 18 CW QSOs on the 20-meter...
Virtually any type of metal will work as a conductor to build your Faraday cage with. It is usually alright if the cage has small holes in it, as long as they are not too large in comparison to the wavelength of the incoming electromagnetic wave. You can also use an existing metal box...
