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

* Check *Tx even* to transmit in even-numbered UTC minutes.  Uncheck
this box to transmit in the odd minutes.  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 a signal in the waterfall.

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

* 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 are clamped at an upper limit of -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!
