CW Numbers Stations

by Guy Denman

Hi All,

For this month I will carry on with descriptions of some more of the families and what has been happening just lately.

M8

Mode ICW. Uses Cut Numbers

T 0, A 1, N 2, D 3, U 4, W 5, R 6, I 7, G 8, M 9, UAAMD MDUUA UAIAU R3 UAAMDx5 = = = 150f Cut

After first message sends AR AR AR MDUUAx5 = = = 150f Cut same after second message
Ends AR AR AR SK SK SK

This is now the usual format, at least 2 others exist.

The station is usually active in the mornings up to 1100. I have heard it at 0600, but as I do not get up early nowadays, not sure how much earlier it is on. I have seen reports from the USA of it being on from 0000 onwards. I am still not sure if the ones we can hear in the UK are being transmitted from Cuba. They are quite often S9 signals, which sound too strong for that distance. Logged an unusual one recently with the last figure of the ID being 4. They are normally 1, 2 or 3.

Some frequencies in use are: 6287 6787 6797 6825 6933 7580

See also Newsletter 7.

M10

Always uses ICW. This station uses a slightly different format of 2 figure decode key. The call up usually starts with 555 but they have been known to use other triplets, 111 222 333 444 777 and 888. These are used on special broadcasts. They have also be known to use up to a 4/5 figure random ID, but only very rarely. Transmission times and frequencies are changed quite often, although they use a set of frequencies to choose from. Sometimes they use two frequencies but not always. Regular schedules all use 2 parallel frequencies. The speed the message is sent is variable, usually the later message is sent at a faster speed. Call and first message 17 WPM later messages up to 25 WPM.

Call Preamble Message Ending
555x3 571x3 46 (R5) 571x3 75 75 46 46 = = 46x5F = = 75 75 46 46 000

They can have up to 4 IDs in the call, in this case the call would be
555x3 571x3 46 275x3 25 049x3 16 435x3 41 (R5)

Then the preamble would be the same, message the same but the ending misses off the 000 and carries on to the next call which would be 275.

There is a regular sked with these 4 IDs on Saturday, Sunday, Monday and Wednesday at 1645. frequency 4485//5028. Same messages repeated for 4 days.

The message can also sometimes be split into 2 parts with a different decode key for each part, but in this case the call gives the total amount of groups in the message.

Frequencies that have been used are:
3385 3834 4029 4305 4485 4541 4573 4775 4834 4882 5007 5025 5040 5060 5085 5155 5276 5290 5301 5295 4525 5471 5503 5521 5554 5702 5737 5760 5860 6204 6758 6780 6801 6835 6943 7380 7404 7475 7845 8111 8175 8190 9164 9369 9386 9455 9971 10582 10922 11415 121?? 125?? 13405 14977 14650 14562

Some skeds active at present as of 9 January 1998

Sunday 1645 3385// 1810 4029// 1920 5471//
Monday 0820 8190//9164 1645 3385 // 1920 5471//
Wednesday 1645 3385//4485
Thursday 1810 4029//
Saturday 1645 3385//

Schedules are Monthly, twice Monthly, or weekly. always repeated within the same week. Special schedules (irregular) may be daily. Another slightly different format has been logged recently, the station comes on at 2000 on 3824. It is not regular so may be heard any day of the week.

Format is:
Call 111x3 55013x3 30x3 for 5 minutes
55013x3 02 02 30 30 = = 30x5F {Always 30 groups} = = 02 02 30 30
does not end with 3 zeros as the normal M10

It is sometimes hand sent, when all the rest of M10 are always auto sent. Was on Friday 12 June to ID 12127

See also Newsletter 8

M12

Mode Usually ICW but has been known to use MCW.

The call is sent fairly slowly at about 15 WPM but the preamble and messages are usually sent at 30 WPM, single 5 figure groups, although slower and faster speeds have been used. They are constantly changing frequencies and transmission times so it is not worth listing them.This is another station that has been noted using the same frequencies and IDs as in 1997. The message is sometimes repeated on a further two frequencies. If the message is sent on the hour then there will be the same message sent at Hour+20 Hour+40, Hour+25 Hour+45, or Hour+30 Hour+50, this depends on length of message and speed sent. Can be found on at any time.

Call Preamble Message Ending
749 749 749 000 R5 No Message
749 749 749 1 R5 1573 143 1573 143
143x5f Pause 000 000

The figure 1 after 749 indicates number of messages,2 messages are very rare. There is one message that keeps on being sent, that has been sent for some considerable time. I first logged it in October 1996 but I know it has been logged before this, usually sent to an ID starting with the figure 3. At present being sent to 314.

The preamble is 792 66 792 66 and the message is always the same. They are still coming on the same frequency as used last year with some variations. Last year on a Friday there was one on at 1600 on 12132 which repeated at 1700 on the same frequency. It is on again this year at 1600 on 12132 but now is the usual format, coming on at 1620 on 13544 and 1640 on 14728. ID was the same 963.

More about M12 to be found in Newsletter 14.

Activity

It is still high this last month. M29 had a particularly busy day on Thursday 11 June. I heard it six times sending messages, also G4 was on at the same time.

M3 is still coming on the same frequencies as last year, and in some cases sending the same messages. It was on Friday 12 June at
0800 on 5365 041/00
0830 on 5624 017/00
0900 on 5050 012/00
and 0930 on 6430 552/00 an exact repeat of 1997.

M53 came on friday 5 June at 2000 with one of its very rare double messages, call was 747.750.016 Message to 750 was 30 groups, followed by a message of 33 groups to 016.

Thats all for this Month, if anyone finds the morse station information useful I would appreciate an e-mail. If anyone requires further information the same applies.

73, Guy
