To set the proper level of audio drive from {wsjtx} to your radio:
|
|||
|
|
|
|||
|
|
* Click the Tune button on the main screen.{wsjtx} should set the
|
|||
|
|
radio into transmit mode and generate a steady audio tone at the
|
|||
|
|
amplitude that will be used for a generated JT9 signal.
|
|||
|
|
|
|||
|
|
* Listen to the generated audio tone using your radio’s Monitor
|
|||
|
|
facility. The tone should be perfectly smooth, with no clicks or
|
|||
|
|
glitches.
|
|||
|
|
|
|||
|
|
* Open the computer’s audio mixer controls for output (“playback”)
|
|||
|
|
devices and adjust the volume slider downward from 100% until the RF
|
|||
|
|
output from your transmitter falls by around ten percent. This will
|
|||
|
|
be a good level for audio drive.
|
|||
|
|
|
|||
|
|
* Alternatively, you can make the same adjustment using the digital
|
|||
|
|
slider labeled *Pwr* at the right edge of the main window.
|
|||
|
|
|
|||
|
|
* Toggle the Tune button once more to stop your test transmission.
