If you do not want to take apart your baofeng, you can still get COS.

Build this simple 1 transistor circuit

Even if the volume is all the way down, the COR detect still goes off when
it gets a signal due to a DC offset in the radio i think. Just make sure
you turn off the voice in the UV5R so it doesen't go off when you press
buttons.

See my portable AllStar node on my qrz.com page
