Hi,
I just took this opporunity to sync my DB and draw some conclusions. IDs
referred to hereunder are the serial record number in Smolinski's DB.

Now, time for some SQL wizardry with 'GROUP BY' tricks :
My DB has some 47722 logs, 16703 of them are E10 likes. It is mainly
drawn from Smolinski's DB but with some extra correction (logs expressed
in MHz removed when not able to correct them, typos corrected when
noticed on time and asked to original submitters, logs in the future of
their date of submitting due to confusion in date formats, etc...)
If I take apart logs the comments of which contains the followong
strings 'CIO2', 'MIW2', 'KPA2', 'SYN2', 'VLB2', there are 10838 records
remaining mainly composed of regular H+00 and H+30 transmissions plus
the E10As.
After having put all logs starting between H+01 and H+29 to H+00 and
those starting between H+31 and H+19 to H+30, I grouped the comments and
the resulting starting times
This gives 5203 distinct couples. I then do a selection retrieving
record with identical comments and different starting times, and
manually browse the results.
Bingo !

So, as we can see, there are many apparent repeats. I say 'appearent'
because this approach suffers some flaws.
- It relies on a consistent type of commenting a log
For instance :
1 log by monitor A at 1230z 'EZI 62 ZAGXS' and the same
tx at 1800 but with 'EZI 62 ZAGXS weak' will not be detected
- It is not exempt from input flaws; although it could be easy to
determine with the number of occurences from the original table.
Ok, so far so good. The existence of repeats has been verified. An we
already have some leads to check.
For instance :
"Are these repeats consistents over a long time, or do they appear for
some time and then vanish ? "
"In the later case, are repeats more frequents when there are string
msgs ? "
A more thorough analysis is needed, but as it is nearly 0200B, I will
stop here (Pillow is calling and it has a loud voice). Maybe will I
publish a fully detailed study on that topic if interest is shown.

From the top of my head, the longest ever running msg I can remember
was 68 FSTYL on YHF.
First log by John Maky
2000-01-13 0230 7918 (id=18721)
Last log by Gallus Galus
2000-03-07 0230 7918 (id=21292)
So it ran for at least 55 days.
The previous log for YHF at this time slot with a different msg is from
1999-12-30 (id=18283), the following one dates from 2000-03-21.
So, at the most 68 FSTYL ran from 1999-12-31 to 2000-03-20, i.e.
possibly for 80 days.
