The two thin yellow wires have been added. - Please click to enlarge.

Subtle changes occur from time to time in the design of the radios and the fobs and the Hamvoip software. I am aware that now, in some cases the thin yellow wire on the right may need to be connected at the other side of the 10 K surface mount resistor. On the same solder pad as the blue PTT wire coming from the chip.

This page outlines a simple way to add indicator lights to the front panel of a CM108 based Allstar node. 

The blue LED is the PTT indicator and the green one is the blinking ” keep alive ” LED.

The black wire goes to ground on the body of the Rpi.

This setup is particularly suited to my Classic CM108 based Allstar Node Design. : LINK

Be aware that it is also possible to connect Tx and Rx indicator lights on the Raspberry Pi itself via the GPOI pins. This, however, does demand quite a high degree of coding ability and so is outwith the scope of this Allstar for beginners website.
