Hi Roger,
Yes, USB, dial frequency 1839 for FST4. Info on K1JT's modes and
download of software is here. First study the WSJT-X doc pdf file and
then Quickstart for FST4 and FST4W.

FST4 can be used with TX periods from 15-300 seconds. Signal to noise
capabilities increases with longer periods. At 60 seconds, the advantage
over CW with great ops on both ends is in the range of 15 dB. FT8 is
about 10 dB. Signal reports computed by the software are signal to noise
ratio for 2.8 kHz bandwidth.

You guys feed audio into an SSB rig for these Computer modes, right?
So which sideband do you use on Top Band?
IE if you are on 1840kHz with a 1kHz tone, are you on 1839 or 1841?
