6.3.1.3 CONFIG: TX
Select the parameters on the top line to be edited using the [←] [→] arrow keys. Observe
the Data/Symbol rates on the bottom line. Press ENTER
CONFIG: TX: TX-IF
Three TX settings can be set from this menu. Select the parameter to edit using the [←]
[→] arrow keys. The options for the TX carrier are shown in parentheses. To change the
settings use the [↑] [↓] arrow keys. Select either ON, OFF, or RTI, then press ENTER.
IMPORTANT
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.
Having this feature enabled does not affect the internal IF loopback feature.
But, 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. USE THE RTI
FEATURE WITH EXTREME CARE!
