FST4W

hb9tmc
WSJT-X 2.3 introduces two new modes, FST4 and FST4W.
FST4W is intended to be used as beacon-mode, like WSPR, it offers a bit better sensitivity for the same parameters and spots are already being uploaded to wsprnet.

It would be nice if wsprdaemon could be used to decode FST4W(-120) as well.
Unknown yet are the used frequencies. On 2200m and 630m they use the same spectrum as WSPR, on 160m the preset spectrum is the 200 Hz above the WSPR-spectrum, but I don't know if that decision is definitive.

If the developers choose to use the 200 Hz above the WSPR-Spectrum also on the HF-bands, it might be best to extend the passband to 400 Hz, to decode WSPR and FST4W using only one receiver slot.

Adding support is on my todo list
