Candidate releases are intended for beta testers, WSJT-X 2.3.0-rc1 offers the new modes FST4 and FST4W designed for use on the LF and MF bands
WSJT-X 2.3.0 is a program upgrade offering two new modes designed especially for use on the LF and MF bands. FST4 is for 2-way QSOs, and FST4W is for WSPR-like transmissions.
Both modes offer a range of options for T/R sequence lengths and threshold decoding sensitivities extending well into the -40 dB range. Early tests have shown these modes frequently spanning intercontinental distances on the 2200 m and 630 m bands.
Further details and operating hints can be found in the
