Hello TD ...
"what component is P1" ?????
maybe it is simply a resistive trimmer or a potentiometer ???? perhaps !!! HAHAHAHA
?
don't tell me you don't know what P1 is because I don't believe it!
?
this diagram is just an example of how a simple dynamic compressor with a handful of passive components can be made, how to insert it and where to insert it in the ?BITX is something you have to decide, study it a bit and look at the diagram of the part receiver of the ?BITX (from the volume potentiometer to the speaker) and see if you need it as an input to the BF amplifier (LM386) or if you want to insert it in parallel with the output before the headphone jack.
