Re: I7SWX PTT Pop Mute
You might try taking the "+12V" of Gian's diagram from pin 8 of the LM386, which is only at 12v when the LM386 is powered up for receive.toggle quoted messageShow quoted text
I don't really know what all "+12V" into pin 7 might do, it certainly is not something written up in the datasheet.
But not much point in doing that when the LM386 is not otherwise powered up, which is the case during transmit.
