FST4W is used in the same way as WSPR, but FST4W has significant
|
|
advantages for use on the 2200 and 630 m bands. By default the
|
|
central *Rx Freq* is 1500 Hz and *F Tol* is 100 Hz, so the active
|
|
decoding range is 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 FST4W 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.
