Yes. That is exactly why I have suggested that a WOLF transmission should have a few seconds of unmodulated carrier (or perhaps identifiably modulated - wobble) every few minutes. Also that any GUI-based WOLF front end should include a spectrogram-type window. This would allow WOLF transmissions to be seen without knowing in advance that they were there, and would also help frequency alignment. This would overcome one of the real difficulties in using the mode for random QSOs. Mike, G3XDV (IO91VT) http://www.lf.thersgb.net
