  847 847 847 000 R5      Repeat is 4 times
This format can easily be confused with M12. this is another that is coming
on with a different ID each month.Second Monday and Tuesday each Month 2100
Winter 2000 summer.

Sent in ICW very rarely in MCW  Another group constantly changing
frequencies and times. Can be found on anywhere between 3.8 and 12 Mhz. Can
be recognised as it is sent very slowly, about 9 WPM, and the signal is
very strong in the UK.Messages are usually about 23 groups but they have
been known to send up to 80 groups The message is sent four times in  a
period of 4 weeks.Has been logged between 1600 and 1000 the next day,on the
hour but transmissions at Hour+30 and Hour+ 50 have been noted.A popular
time seems to be at 2100 and 2200.
Repeat sequencies that have been logged
On the same day 1 Hour later on the same frequency.
On the same day 1 Hour later on a different frequency
On the next day at the same time on the same frequency
On the next day at the same time on a different frequency
On the same day 2 Hours later on the same frequency and also the next day
the same
The sequence is then repeated 2 weeks later with the same message. The next
transmission will be 2 weeks later, with a new message on a different
frequency.
It has also been noted that some only transmit once a month.
Now that I have been logging these stations for 1 year, some of them are
coming on the same frequency that they were on 1 year ago, so it would seem
that they are using a twelve month cycle of frequencies.
I have also found out that thay are coming on at the same time each month.
253 comes on the first Thursday and Friday each month. They all then repeat
2 weeks later. There are 2 Schedules that come on at the same time each
Month, but use a different ID each month. One comes on the second Thursday
and Friday each Month at 1600 and 1800 in the winter and 1 hour earlier in
the Summer.
