FST4 is is designed for making 2-way QSOs on the LF and MF bands. Do
|
|
not confuse it with FT4, which has a very different purpose! Most
|
|
on-screen controls, auto-sequencing, and other features behave in FST4
|
|
as in other modes. However, operating conventions on the 2200 and 630
|
|
m bands make it desirable to have additional user controls that set
|
|
the active frequency range for decoding. Spin boxes labeled *F Low*
|
|
and *F High* set lower and upper frequency limits for the FST4
|
|
decoder.

Decoding limits are marked by dark green angle-bracket symbols *< >* on
|
|
the Wide Graph frequency scale:

|
In general the specified range should be no larger than you need, since
|
|
detected transmissions in modes other than the selected FST4 sequence
|
|
length will be undecodable and will slow down the decoding process.
|
|
|
|
If *Single decode* on the the *File | Settings | General* tab is
|
|
checked, the decoding range is further limited to the *F Tol* range
|
|
around *Rx Freq*.
