New WSJT candidate release features FST4

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
