	For example if a transmission is observed on the third day of the month on 6215 kHz at 1400 UTC and there was not a transmission in the same time/freq slot the day before (second day of the month), it is quite probable there will be one on 6215 kHz at 1400 UTC on the fourth day of the month. The transmissions on the third and fourth will contain the same message. There is a trend to also have the same time/freq slot filled about 15 days later, in this example 6215 kHz would again be used in the 1400 UTC time slot on the 18th and 19th of the month.

	The Korean language numbers station V24 is believed to originate from South Korea, although this has never been confirmed and the exact transmitter location is unknown…at least unknown to anyone who is talking about V24. V24 has been observed transmitting since the very late 1990’s, with numbers stations being in use from South Korea at least as far back as the early 70’s. North Korea at one time used numbers stations also, but the current popular belief is that the North ceased numbers operations around 2000.

	Of interest, while looking at my old 4th edition (1979 printing) of "The Confidential Frequncy List" I found an entry for 5715 kHz. The notation said "NUMBERS in KK". I think that is a fairly strong indication that V24 has been around for three decades or more. Now if I can just locate my 1st or 2nd edition of that list.

	Transmission times as reported are between 1200 and 1620 UTC, occurring on the half hour or the hour with the exception of a notable time slot at 1620 UTC on a few days a month. Again, it is very possible V24 is using other time periods but propagation might be biasing the perceived schedule. The recently reported/added frequency of 6730 kHz also has (one time) been reported at an odd time period, with a 1445 start time. Assuming this was not an error in reporting this might be the only reported departure from the XX00, XX30, and 1620 start times.
