Sorry you are having this problem. If
you shifted the Raduino1 connector, and the transmitter is really
working, I don't see how that can cause your problem since all the
signals must be working for the transmitter to work. It seems like
you will need a signal source and a scope, although you could
manage without the scope, to see where the problem is.
If you don't have those tools, you could check that all the stages
that have RX voltage and make sure that the transistors in those
stages have the appropriate DC voltages, i.e. Q10, Q11 etc.
