Sounds like you have the same problem I had- side tone ok, seems to be
transmitting,
just as deaf as a post! I haven't got the circuit in front of me here at
work, but I strongly suggest that U5 is ok. Now, trace through from the
transformer through to the next chip (is it U4?). Resolder your joints as
you go, make sure you haven't got any bits shorting out anywhere top or
bottom of the PCB. Than't what I did and Presto, it sprang to Life!!
Let's know how you go....
