*NEW FEATURE RTI means RECEIVE/TRANSMIT INHIBIT. When selected, it will prevent the TX carrier from being transmitted, until the demodulator is locked.

To avoid the Tx Carrier from being turned off when the demodulator loses lock for a very short period of time, the demodulator must be unlocked continuously for a period of 10 seconds before the transmit carrier is inhibited. This time interval is fixed and the user cannot change it.

Note: Having this feature enabled does not affect the internal IF loopback feature. But, please be aware that if an external IF loopback is attempted (connecting an external cable from the Tx IF output to the Rx IF input), then this will not work! (The Tx carrier cannot turn on until the demod is locked, and the demod cannot lock, because the Tx output is off. The net result is that the demod will not lock, and the Tx carrier will not turn on.

PLEASE USE THE RTI FEATURE WITH EXTREME CARE!.
