Thanks Mike:
RRC Setup must be correct, RX audio is OK, but my friend tells me, when he push PTT, he doesn't have any indication in control side about the remote side is transmitting (remote side is efectivilly transmitting). He is making the tests with both RRC in the same router (Local Network).
He also says that s-meter movements (in control side) are smaller than in the remote FT-2000.
Is it like this?
