I do not make YouTube videos because I want people Overcoming adversities essay read and think about things. I want people to learn from my experiences at their own pace and this can't be done with everything whizzing by in a video.
The project was started on a kind of a whim when I discovered the chassis of an old project in my junk box and then proceeded from there -- mostly through a long series of trial and error -- with lots of errors -- before I settled on a good Armstrong type design.
This story has Overcoming adversities essay lot of technical detail in it and it can be instructive, but I would ask you to please treat this article as a story because it is really meant to be read for entertainment and not as a construction manual.
If you think you might like to build a similar project and have any questions, please send me an E-mail using the link at the end of this story. You might want to know that there is a kit available that is almost identical in its design to my radio's design.
I don't sell or advertise, but you can easily find the company that makes it by doing an Internet search. The Armstrong "Crystal Radio or its good looking brother, the Geezerola Senior is fun, cheap, quick and easy to build and it performs hundreds of times better than a straight crystal radio possibly can, especially with a short antenna.
If you are interested in building a very simple shortwave regenerative radio, you might want to consider experimenting with the coil of my Armstrong "Crystal" Radio, but with fewer turns for shortwave. I think it is important for young people to build something simple enough that they can easily understand it, but that performs well and will be something that they will be proud of 50 years from now as I am of my first Armstrong radio.
If you are an experienced builder, this might be the ideal project for you to think about. Anyway, here is the story of how I came to start this project and of all the things that happened before I finally ended up with something that I liked.
I hope you find this story entertaining. This story can be divided into the following chapters. You may not be interested in reading all of them in sequence, but if you are here for the story, I suggest you do read them in sequence.

Chapter 1 Why build yet another radio and what got me started During the last couple of years, starting inI've been restoring old radios and completing old projects that were put on hold back in my high school days 50 years ago.
This activity has rekindled my old passion for radios and now I'm hooked once again. If that weren't bad enough, I suddenly got the itch to begin building radios from scratch once again.

What could be a better way to begin than to begin at the beginning with something really basic and build a direct conversion receiver or maybe an Armstrong type regenerative radio? Well, that's what I ended up building, an Armstrong type regenerative radio, but unlike the regenerative radio I built inthis time I decided to use s technology instead of s technology and use a Field Effect Transistor FET in place of the venerable old 1H4 thermionic tube that I used as the detector of that early project.
My FET regenerative radio project. Notice the really neat little tuning dial. Boy, they sure don't make nice ones like this anymore. It just begged me to make radio using it. Using a shortwave receiver, I listened for the regenerative signal when the unit was in oscillation and by matching my dial to the radio's dial, I was able to put calibration marks on the dial face not shown in this photograph.
In there I found this excellent little box with a tuning capacitor and a wonderful dial mechanism already mounted on it. The box was from an abandoned project that never worked very well, but just looking at it got my "creative juices" flowing once again.
The box and its dial looked as "cute as a bug" and I remembered how, back aroundI had intended it to be a direct conversion receiver and the companion for the 80 and 40 meter ham band transmitter I had just made.
Direct conversion receivers can really perform well, but this one was a failure. No matter what I did to protect them, the delicate and expensive dual gate FETs I used as a mixer kept failing. After a while I stopped trying to make this little radio work and just tossed the project into my growing junk box because by this time I had a much better receiver at my disposal.
Now, when I opened the cabinet up for the first time in 40 years, I saw that the original circuit board was missing. I didn't care that I couldn't find the circuit board because it was built to an unreliable design and I wanted to build something better anyway.
This then is the details of the evolution of my latest radio project from a Hartley bipolar transistor design that worked terribly to a Armstrong FET design that works great.
Chapter 2 Why reinvent the wheel? So, there I was with this really neat little radio cabinet with its very nice vernier dial and tuning capacitor already installed and there it was just begging me to do something with it.
The more I looked at it, the more " regenerative receiver regenerative receiver " kept popping into my head. I also considered building a direct conversion radio, but the fact is, a regenerative receiver can easily be used as a direct conversion detector simply by turning up the regeneration.
A regenerative detector is much more robust than any dual gate FET mixer, it is very sensitive to weak signals and it will demodulate AM in addition to single side band and Morse code.
So that settled it, this little box was going to be a regenerative receiver.General scholarship are for everyone. Many students are unsure of their major. Some are adult students returning to school after years of absence.
