+NOTE: Several options are available for circumstances where fast QSOs

+to toggle use of the Tx2 message rather than Tx1 to start a QSO.
+Similarly, double-click the *Tx4* control to toggle between sending

+only if you are reasonably confident that no repititions will be

 your Tx frequency to that of a tail-ender who called you somewhere
 else in the FT8 subband.
 
+NOTE: The FT8 decoder can often copy several overlapping signals at
+nearly the same frequency.  However, in crowded band conditions you
+will often find it advantageous to move off the frequency of the

+*Shift+F12* provide an easy way to move your Tx frequency in 60 Hz
