I understand, Norbert, now. Hmmmm....the information I read leads me to believe (and it's stated as such) that the greater frequency of Pilot tones provides an aid to tuning. IMHO, it seems to me that the pause time that you stated is a bit too long to provide benefit. I don't know where I'd pause for an equivalent of 20 characters.
Right now, "I" am seeing a Pilot tone only at the beginning of the CQ in which I included my callsign, City/State and Locator. I think it could be inserted by the operator at the end of each line of CQ for tuning. I also noticed that without looking at the screen, I instantly recognized the signal by WB4MWD by virtue of the inclusion of the Pilot tones. First time I've been able to identify an exotic mode by ear per se, so the tones have an additional value. I think we just need to adopt a reasonable protocol for the tone use and also allow for manual insertion as needed.
