I have checked the Anntena Connections, I even opened up the Transmitter and with a volt meter, I checked the connection from the tip of the antennea to the spot were the antenna mount is soldered to the circuit board, And the Connection is fine, But again as soon as the transmitter anntena is let go by my hand, the transmitter no longer sends the signal to the receiver, Don't laugh, But I went as far as connecting a wire to the transmitter anntena with a small aligator clip, while holding the other end of the wire in my mouth and IT WORKED! But I'm not flying like that.(is that what they mean when they say "FLY BY WIRE"---LOL....... I'm out of Options should I get a new Tx...........?
