sequence lengths, respectively. (Note that the actual start time may
have been earlier if repeats of early transmissions were required.)

decoding, which takes advantage of naturally accumulating information
during a QSO.
For CW mode on SHF and microwave EME WSJT-X can be used to do Doppler
shift correction if desired:
- Check the *Settings -> Radio -> Mode -> None* option, this stops _WSJT-X_
from trying to set the mode of your rig.
- Put you rig into CW mode as normal.
- Before transmitting press *Tune* in _WSJT-X_, no tones will be
transmitted as the rig is in CW mode, but importantly WSJT-X knows
your are transmitting and adjusts the Doppler shift correction as
needed for the currently selected Doppler shift correction mode in
transmit.
- When you have finish transmitting CW press *Tune* again to revert to
receive mode and the correct Doppler shift correction for receiving.
NOTE: The above assumes you are already set up for _WSJT-X_
<<VHF_SETUP,Doppler shift correction>> with working CAT control, and
*Monitor* enabled etc..

these program features, all of which are of special interest for EME
