Understanding Synchronous Detection
To boost your understanding synchronous detection, let’s examine the impact of selective fading, distortion and weak signals on the AM detector in your receiver. Read more
Legacy AM Receivers – How Envelope Detection Works
Before we explore synchronous detection, let’s make sure we understand how envelope detection works. After all, it’s been around for a century. Read more
Enjoy Synchronous Detection on your Shortwave Radio
Most new shortwave receivers let you enjoy synchronous detection. It is an important and very useful feature if you listen to AM broadcasting on medium and short waves. Let’s find out more. Read more
Define Hobby – What it Means to Me
How do you define hobby? Interestingly, the concept of a hobby is very loosely defined. So I will take a crack at it. Read more
Millennial Hams – Today’s Generation Steps Up
Ham radio will look much different fifty hears from now. How different? The activity of millennial hams today might provide some clues. Read more
Creating Frequency Modulation in GNURadio
Let’s experiment with creating frequency modulation in GNURadio. Along the way, we will learn about deviation and voltage controlled oscillators. Read more
Creating Amplitude Modulation in GNURadio
Let’s have some fun creating amplitude modulation in GNURadio. This little experiment teaches the basics about modulation and is an easy way to learn more about GNURadio. Read more
2017 Review – Looking Back at the Year
Time for a 2017 review. During the year, my interests shifted more towards software defined radio, but the variety of articles remained broad on my web site, Making It Up. Read more
DesktopSDR Captivates with Matlab and RTL-SDR
Once in a while, I come across a learning project that is truly engaging. So, I need to tell you about how DesktopSDR captivates my attention, and might do so for you, too. Read more
