Hi Curt, I have tried a number of the AGC circuits floating around out there. They all seem to work, but do not handle large (>1000 microvolts) signals. Out of frustration, I have developed an AGC con

Hi Armin, I developed this AGC because all of the others act on the audio signal. When the signal is really large, the audio is already distorted so we just control a distorted signal. Please see the

Hi Jerry, Thanks for your input. I agree, his circuit is elegant & simple . I wanted to build an AGC and Squelch circuit on a separate board and just remove one component & connect two wires to the Bi

Hi Harvey, I pulled the board and measured the gate voltage on the BS170. With no RF signal it reads 3.2629v

Thanks for all the information regarding the Nextion Displays.. I have finally installed the 5" display and it works very well! My question is, Has anyone devised a way to eliminate the buzzing noise

How does this topic, even remotely relate to the BitX subject?? Amazing.. Rich

Hi Bob, Thanks for the response.. Kind Regards for all Rich

Thanks for the list Arv. I joined here to discuss the technical aspects of the radios. I certainly don't need any of the High & Mighty attempting to force me into feeling guilty because I am not a vic
