<div>Skyler, Short answer is No!<br><br>My experience
with the sound fobs that look similar to yours , You will still need

to get that logic other than soldering a wire to the pin.<br><br>As

It looks like it already has both LED's installed. I am assuming the red led is the same as the transmit LED.
If this is so, does that mean I don't have to solder to the tiny pin on the CM108 and I can just drive a transistor with the same wire as the LED for PTT?
