Do not confuse FST4 with FT4, which has a very different purpose!
|
|
FST4 is is designed for making 2-way QSOs on the LF and MF bands.
|
|
Operation with FST4 is similar to that with other _WSJT-X_ modes: most
|
|
on-screen controls, auto-sequencing, and other features behave in
|
|
familiar ways. However, operating conventions on the 2200 and 630 m
|
|
bands have made some additional user controls desirable. Spin boxes
|
|
labeled *F Low* and *F High* set lower and upper frequency limits used
|
|
by the FST4 decoder, and these limits are marked by dark green
|
|
angle-bracket symbols *< >* on the Wide Graph frequency scale:

It's best to keep the decoding range fairly small, since QRM and
|
|
transmissions in other modes or sequence lengths will slow down the
|
|
decoding process (and of course will be undecodable). By checking
|
|
*Single decode* on the the *File | Settings | General* tab, you can
|
|
further limit the decoding range to the setting of *F Tol* on
|
|
either side of *Rx Freq*.
