<DIV>Skyler, Short answer is No!<BR><BR>My experience
with the sound fobs that look similar to yours , You will still need
to solder to Pin 13 to get the PTT logic. No way around that as on
the CM-108 chip Pin 13 is not connected to anything so no place else
to get that logic other than soldering a wire to the pin.<BR><BR>As
for the COS signal (CM-108 Pin 48) that can be gotten from the left

the COS line to Pin 48 on the sound chip. CTCSS can be retrieved
from the right side of volume up SW2<BR><BR>The Green LED is still

<BLOCKQUOTE type="cite"><PRE>I previously got the CM108 sound fob from startech and had to solder to the tiny pin.
With this one

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?
