The walkie-talkie is getting audio from two sources. I suggested using a
splitter to combine the sources, but this will load down the output
transistors unless we add two resistors in series before the splitter. 10k
is fine. This will attenuate the current of each signal. We could use a
summing amp if we want to avoid the attenuation, or we could just turn up
the volume.

Will test G1 audio out AC coupling tonight after 5moF
