value

equals the desired frequency of operation.

Note:

The ratio of 300/1000 denotes a 30% transmit duty cycle.

Once observation of radio performance is complete, turn off transmit operations by typing:

L1_TEST,STOP

Note:

Each figure in this section shows a typical transmission spectrum or power measurement of a locomotive radio.
