We’ll admit we haven’t heard of the AGS-38, it reminds us of the shortwave receivers of our youth, and it looks like many that were made “white label” by more established (and often Japanese) ...

Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider ...

Affiliates of the public radio satellite system in the United States are in the process of completing a major receiver switchover. The project involved deployment of XDS headend hardware and the XDSv7 ...

This article is intended to introduce the beginner to the interesting and challenging art of high frequency radio design. It is also intended to entice the seasoned professional to take a deeper look ...

Although GRC (the GNU Radio Companion) uses the word radio, it is really a graphical tool for building DSP applications. In the last post, I showed you how you could experiment with it just by using a ...

While it hardly qualifies as cutting-edge technology, the project described here did provide a solution to an annoying problem I have faced several times: How do you get a decent off-air signal from ...

Testing FM receivers is not that much different than testing other pieces of audio equipment. Appropriate tests include the big six: level, frequency response, THD+N, phase, interchannel crosstalk, ...

The NAOJ ALMA Project and Advanced Technology Center have successfully fabricated corrugated all-metal 3D-printed horns for the ALMA Band 1 receivers (Radio Frequency: 35–50 GHz). Since around 2015, ...
