I am looking for a circuit to use between my RCI-2670 amateur radio (which requires a 400 Ohm Dynamic microphone-like a CB) and my small handheld Yaesu microphone (2K Ohm Condenser).
I want this circuit because I have a RCI-2670 and a Yaesu FT-530 in my mobile. I want to have one microphone with a switch between the two radios. I saw the circuit in a QST or 73 magazine several years ago.
Any help would be greatly appreciated.
