The last V24 transmission, that I know of, was on November 9, 2018, 1500 UTC, on 6215 kHz. That transmission was normal. To the best of my knowledge, from that day to today (November 22, 2018) V24 has missed every historically scheduled transmission. Further, during that time I have monitored every past used V24 frequency from before 1100 UTC to past 1700 UTC, every day (as I have for many years, minus a handful of days in the past 10 years), all with no results.
Either V24 has not transmitted since Nov 9, or they are using an entirely new set of frequencies, or have shifted to a different time set. V24 has occupied roughly the same times of transmission, between 1100 and 1700 UTC, for at least 15 years.
A real possibility is that V24 has been inactive but will eventually return to the air. This has happened several times in the past, missing every transmission for a week or more. At one point V24 was off air for several months, only to return as before.
Time will tell if this is temporary or not, however since there are only one or two more scheduled transmissions this month, and V24 has already missed the companion transmissions to both of those, it is quite likely that the next time we might hear V24 will be on Dec 1, on 6310 kHz, at 1530 UTC.
