FST4W has significant advantages over WSPR for use on the 2200 and 630
m bands.  As for WSPR, the default Rx Freq is 1500 Hz and F Tol is
100 Hz, so the active decoding range 1400 to 1600 Hz.  However, for added
flexibility you can select different center frequencies and F Tol values.
We expect that usage conventions will soon be established for FST4 activity on 2200 and 630 m.

A new drop-down control below F Tol offers a round-robin mode for
scheduling FST4W transmissions:

If three operators agree in advance to select the options 1/3, 2/3,
and 3/3, for example, their FST4W transmissions will occur in a fixed
sequence with no two stations transmitting simultaneously.  Sequence 1
is the first sequence after 00:00 UTC.  For WSPR-like scheduling
behavior, you should select Random with this control.
