I saw that it was possible to use a "tone spacing" * 4, could it help to decode
a signal that would have suffered from Doppler?
How to decode this signal in reception? Does WSJT-X do the inverse conversion
in RX mode?

Hi David,
the tone spacing adjustment is only on transmit and is designed to
accommodate transmitters that divide the modulated RF to make the
transmitted signal, usually to make transmissions on the lower LF bands.
They would normally use hetrodyne mixing to up-convert before the IF
receiver so no tone spacing adjustment is needed there.
Have you considered experimenting with one of the JT9 fast modes or even
MSK144 if you want a block encoded mode like FT8 or even ISCAT for a
stream encoded mode that can work well with complex and variable
propagation paths like aircraft scatter.
