Hello Maco! Of course there are no global "correct" parameter values. User Guide sets the T/R to 15 s, but any value would work except the same T/R value and the same Tx even/1st value and then both stations would send and receive at the same timeslots!
The CW ID is really a matter of local regulations. E.g. in Finland we don't need to send it at all as the monitoring station could decode MSK144 at a short range better than any CW, typically no human listening needed. The same with FT8. In many regions 10 minutes is set in the regulations and so the CW ID should be set to 10 and possibly activate the 'CW ID after 73' as it could be the last transmission. The CW ID is intended for a strong signal identification and your QSO partner normally would not hear it, just short pings. For the regulation purposes the CW ID is working as it should. For QSO point of view it may steal your '73' if you send it only once and you are using T/R 5s. 73, Reino OH3mA From: Marco Calistri <py1...@outlook.com <mailto:py1...@outlook.com> > Sent: Tuesday, May 13, 2025 10:23 PM To: Reino Talarmo <reino.tala...@kolumbus.fi <mailto:reino.tala...@kolumbus.fi> >; 'WSJT software development' <wsjt-devel@lists.sourceforge.net <mailto:wsjt-devel@lists.sourceforge.net> > Subject: Re: [wsjt-devel] CW-ID is not being sent Hello Reino! Thanks for the time you spent for the tests! The main issues, IMHO are: what are the correct parameters both for the CW id time interval and the MSK T/R seconds? Since it's not much worth that CW-ID being working only with few parameters combination that we can't use for normal MSK144 mode. For example here in Brazil the T/R is normally set to 30 s.

I listened to the audio and there is my CW id once a minute! When I set T/R to 5 s, then the CW ID replaces the first MSK144 transmission. When the T/R period is longer, then the last 5 s of the transmission is replaced. If I also select CW ID after 73, then the last 5 s of the '73' message is stolen for the CW ID. The once a minute CW ID transmission may not be the first time of the minute. At least with 10 s T/R sends it at 45 seconds mark. At T/R 5 s the whole '73' message is stolen and no '73' is sent (may be a bug). The CW ID seems to work. 73, Reino OH3mA From: Marco Calistri via wsjt-devel <wsjt-devel@lists.sourceforge.net <mailto:wsjt-devel@lists.sourceforge.net> > Sent: Tuesday, May 13, 2025 12:25 AM To: wsjt-devel@lists.sourceforge.net <mailto:wsjt-devel@lists.sourceforge.net> Cc: Marco Calistri <py1...@outlook.com <mailto:py1...@outlook.com> > Subject: Re: [wsjt-devel] CW-ID is not being sent Hi Andy! In reality I was asking in general the correct usage of CW-ID, which at least here it seems is not working. Then I would like to get the confirmation about it. Best regards, Marco, PY1ZRJ
