At the center of the main window are a number of controls you will
use when making QSOs:

//.Misc Controls Center

* Check *Tx even* to transmit in even-numbered UTC minutes.  Uncheck
this box to transmit in the odd intervals.  This selection is made
automatically when you double-click on a decoded text line as
described in the <<X5,Basic Operating Tutorial>>.

* The Tx and Rx audio frequencies can be adjusted with spinner
controls. These settings are usually set automatically by
double-clicking on decoded text or on thw waterfall.

* The on-the-air frequency of your lowest JT9 or JT65 tone is the sum
of dial frequency and audio Tx frequency.  You can force Tx frequency
to the current Rx frequency by clicking the *Tx=Rx* button, and
vice-versa for *Rx=Tx*.  Check the box *Lock Tx=Rx* to make the
frequencies always track one another.

* The *Report* control lets you change a signal report that has been
inserted automatically. Most reports will fall in the range –26 to
+10 dB.  Remember that JT65 reports must lie in the range -30 to -1 dB.

IMPORTANT: When signals are close to or above 0 dB, you and your QSO
partner should probably reduce power. JT65 and JT9 are supposed to be
weak signal modes!
