One Transistor Regenerative Radio Receiver

A one transistor regenerative receiver based on this design http://home.pacbell.net/lengal/ip/amregen.pdf with some modifications from Charles Kitchin's simple regen http://www.arrl.org/files/file/Technology/tis/info/pdf/0009061.pdf to stabilize the transistor bias. Here is the schematic for my version http://i.imgur.com/pPXKP.png I'm documenting this in a video since I'll soon be tearing this circuit apart to make something new.

Hello!

Tell me, this regenerative radio received signal is SSB?

[caiserECEguy]

@biowolf1977 This radio is for the AM broadcast band so it's receiving AM signals. However, a regenerative receiver like this can be used on the ham bands for receiving SSB and CW.

The reason that your signal is louder when you put it on it's side is due to the orientation of the coil. . But very nice project indeed. Very nice.

@AmericanCryer Thanks for the comment. I realized later that in AM radios with loopstick antennas that the coil is always mounted horizontally. That's probably what I should have done here. I never have gone back to this project. This year I may try rebuilding it for the amateur and shortwave bands.

@caiserECEguy I just got my Amateur Tech class. I am trying to construct a CW transceiver as a club project. I personally want try and build my own Short wave transceiver. But that would be a large project.

@AmericanCryer Congrats on earning your license. I passed Tech+General several months ago and I'm still working on getting my station up and going. Building a complete transceiver would be pretty tough but it's not impossible. Good luck on your projects. 73's!

@caiserECEguy You too. KK4GOB.

hey I like your efforts to make this project run.All the best for ur next.

DON'T BE A DICK AND TRY TO SQUASH MY INTEREST BY ADDRESSING YOUR AUDIENCE AS GRADE SCHOOL KIDS AND SOME HIGH SCHOOL STUDENTS. YOU NEED TO WISE UP AND BE NICE IF YOU WANT TO KNOW OTHER NICE PEOPLE. I DOUBT ANY GRADE SCHOOL KID KNOWS JACK OF YOU. DANG! WHY MUST I TELL PEOPLE BASIC DECENCY THAT IS IMPORTANT TO ME, AND MAKES YOU LOOK BAD.

JUST A FRIENDLY REMINDER FROM A FRIENDLY PERSON. HAVE A GREAT DAY! OTHERWISE I ENJOYED YOU SHARING YOUR TERRIBLE NOISES WITH THE WORLD!!!

THAT IS COOL,
