However, in my 77.5 kHz test scenario, the amplitude doubled as predicted. This antenna can now, for the first time, effectively capture magnetically induced signals across longwave to shortwave bands ...

ORF has Austria's 500-kilowatt short-wave transmitter blown up The whole world can be reached with a unique short-wave antenna from Austria. It could be blown up as early as Thursday.

The SDRs I tested used a relatively new laptop computer and an MLA-30+ 100 kHz-30 MHz loop antenna purchased from Amazon for around $46. I could have used the SDRs with the longwire or indeed any ...

In this paper, a near vertical incident skywave (NVIS) shortwave magnetic loop antenna suitable for engineering applications is proposed and designed, and the effects of its structural form, size, and ...

A smaller antenna is no less the challenge when it comes to designing one that can be carried though, and [Thomas Witherspoon] demonstrates this with a foldable loop antenna for the 2 metre band.

You may have heard that some carmakers will stop offering AM radio. Alan Cross explains the move is part of something that goes beyond just AM radio — way, way beyond.

In this paper, formula deduction and simulation analysis are conducted for the principle composition and configuration form of short-wave vehicle full-loop no-Blind-area antenna. From the generation ...

Article Wideband active loop antenna for general-coverage receivers Wideband active loop antenna There’s nothing better than a long-wire antenna for shortwave reception, but not everyone has the ...

Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...
