| Mozee:
I was trying to build a Regenerative Receiver but It didn't work and I don't know what is wrong with it. The Base-Emitter junction of the BJT transistor with is connected to the base of the JFET by a 33Pf capacitor measures 0 volt! no bias is present and I am having doubts for the 1.1uH inductor located at the base of the JFET, probably grounding the base of the JFET and all the signals which is supposed to go to the base of the BJT transistor. I took this video so please have a look. Also, the schematics are in the video as well. Here you go https://youtu.be/5bnIffITJVI |

Also, I forgot to ask how to know is the reg. rec. is functioning correctly or not using an oscilloscope ? |
| JimRemington:
Judging from the first 15 seconds of the out-of-focus, shaky video, the video is a useless waste of time. Please post a proper schematic. |

It is a Mickey Mouse regen shortwave radio circuit. Does anybody use shortwave frequencies today? My grandmother had a shortwave radio that I heard its awful sounds about 65 years ago but it was not a regen, it was a real radio, a superhet. |

I am new to the entire RF thing! Would you recommend something that actually work!? Ok how do I measure the frequrncy that my reciever is tuned to? |
