Hi Glenn,
You might like the FST4 QSO mode. Same operating procedure as FT8, but
depending on cycle length it can decode below -30 dB.
It is mostly used on 630m but I also had (transatlantic) contacts on 160m.

Hello,
FT8 on 160m pales.
WSJT-X operators customarily running FT8 and FT4 on 80m through 10m HF
bands are likely disappointed with trials on 160m. As one of those
operators I recently ran WSPR on 160m in comparison to working FT8 QSOs
on 160m. In NA EST daytime operation at 2220Z WSPR faultlessly listed a
-28 dBm decode.
Here I suggest we need an improved decode sensitivity for 160m QSOs,
likely needing to be done with a new mode. Granted, the TX and RX times
would have to be increased (Shannon-Hartley Theorem). That would require
additional operator patience and associated protocols for the extended
timing.
