Morse stations

A representative sample of logs received

Unid1

per IB & Tomonori

A mysterious “2” station believed to originate in NE China and heard on 10140.5kHz with very weird messages sent between a “2” marker.

Examples:-

2 marker “305UN550 = 305UN550 + 305UN550 DDDDDDD DDDDDDDDDDD DDDD DDD Q” 2 marker.

IB has mp3 samples available.

M01

Now into its M01/3 “025” skeds till end August, late starts noted.

Freqs heard 4905, 5017, 5280, 6434, 6780

M08a

From the recent logs received it now appears to be a “normal” practice of this station to use the OE & K endings for many TX's, as remarked in Issue 22, it then took us by surprise and on 31^st May and some TX’s reverted to the AR BT endings - wonder how long these will last ?.

As number stations rarely make changes “for fun” , as indicated in the intro, this variant has been assigned the designator M08c from July 04.

A number of “late starts” logged in past couple of months, no preamble or ID sent just straight into mssgs. MS comments, (edited) “ is this another Cuban c’up where they start the tape and forget to switch the TX’er on, or a new, untrained !!, operator.

During the last few days of June a number of “problems” were noted with both M08a and its partner voice station V02a.

Freqs heard:-
3025, 3244, 3292, 3389, 3926(voice QRM), 4028, 4478, 6252, 7519, 7526, 7862, 8010, 8136, 9113, 9152, 9238, 9323, 9331, 10126, 10234, 10345, 10446, 10546, 10566, 10714, 10858, 11565, 12093, 12119

M10

Remains as active as ever with no surprises.
4485, 4783, 5078, 5735/7, 5945, 6801, 6934, 6945, 7380, 7745, 7862, 8011, 8143, 8170, 8175, 8190, 9113, 9161, 9166, 9238, 9323, 9369, 9385, 9958, 10125, 10346, 10446, 11433, 11437, 12227, 12295, 13405, 14563,

M10e, the 4 weekly sked, 09.00z, 5019kHz, suddenly re-appeared on 1^st2^nd 3^rd 4th June, call “111”. Last logged M10e was 10^th Mar.

M12

Wed	09 June	20.00z	9373kHz	20.20z	7696kHz			379 379 379 1
Thu	10 June							again a very long 2 mssg TX for the 05.30z start sked which over-ran its slot times.
Fri	11 June	21.10z	14977kHz					i/p, ending 21.13z
Tue	15 June	21.00z		21.20z		21.40z		“918”skeds on 9923/8123/6823kHz noted same as in 2003

On Monday 28 June this station sent 3 mssgs, this has never been previously logged, the call and mssgs taking 23 mins to send as following sked:


	05.30z	10697kHz	05.58z	12097kHz	06.26z 13497kHz	ending 06.49z
ID	604 604 604 3		840 840 105 105		731 53 731 53	948 81 948 81

A brilliant catch by GD

Minor variations in TX freq/time noted

M13

The 12.30z TX was caught on 9411kHz in early May by GD

The 21.02z TX, 4732kHz 22 May sent ID 764 rather than the expected 746 ??, this was repeated at 21.06 on same freq, so not a miss-logging.

Interestingly the 20.00z, 6947kHz, TX on 7 June started by giving a “Type A” call for 2 mins then changed to its correct one.

12 June	21.00z	5018kHz	the expected call of 931B was replaces by 933
20 June	19.02z	12325kHz	call “261” - a very high freq for this station.

M13b long mssg variant

Sat 12 June

21.00z

5017kHz

call 933A

M13c slow MCW, twice monthly variant.

Thu 3 June

21.00z

5173kHz

“134” 239 23

Freqs heard:-
5173, 5288, 5376, 5518, 5758, 5788, 5918, 5922, 6212, 6332, 6838, 6933, 6947, 8085, 8175, 8497, 8588, 8673, 8677, 9276, 9965, 10427, 11307, 11612, 12325, 12388, 12714, 12834, 13158, 13257

M14

Only the 1^st & 3^rd Fri of month.

On 4 June, 19.00z, 9900kHz, call “263”,
repeat at 20.00z on 9065kHz, - carrier up at 19.40z on 9060kHz then QSY’d to 9065kHz
On 18 June, 20.00z, 9055kHz, call “263”

Now a conundrum !!!

On Sat 19 June, 18.00z, 7485kHz an M14 type constant carrier keyed audio tone MCW TX was heard warming up just before the hour with several long strings of “Dits” in much the same way as that observed with the 1^st & 3^rd Fri M14 sked. Calling “707”, DK/GC “198 198 75 75 = =” and 5F’s as doubles, close to a S9++ b/c station so copy difficult. Ended just after 18.19z with “= = DKDK GCGC 00000” (long)

Is this a possible additional M14 sked starting up ??, or one previously unmonitored. (Ed)

We will be watching.

M18

CW 4F

Moved freq to 4503kHz in May (per AB)

M23

Interesting skeds for this station found by LW at 07.30z & 16.00z daily on 7770kHz, 3fig call for 10 mins changing daily.

Another sked found on 12075Khz still under investigation, but appears to be similar.

M24

Heard at 10.30z on 12070kHz, Mon 10 May, clg 459 459 130 130 BT BT and at 11.00z on 10470kHz with the repeat, this appears to confirm the expected time change from 11.30z/12.00z.

The former Tue 18.00z/18.30z TX’s noted at 17.00z/17.30z on the predicted freqs of 9125/10555kHz

The repeat of the Mon 12.00z 10210kHz TX , at 12.30z, was found on 11439kHz by GD

Mon 31 May	10.30z	12070kHz	call 762. Repeat 11.00z 10470kHz
Mon 7 June	10.30z	12070//10471kHz	call 762
“	12.00z	10210kHz	call 464. Repeat at 12.30z 11439kHz
Tue 8 June	17.00z	9025kHz	call 239
	17.30z	10555 kHz	rpt above

M24a

(2 mssg variant)

Wed 9 June, 19.07z, 14480kHz i/p, ending 19.12z with “= = 384 384 75 75” then started calling “762” and a second DK/GC “901 901 77 77 = =” ended just after 19.20z

M44a

This rare station logged on Mon 21 June, details awaited

M45

Tue & Thur at 17.02z, hand keyed.

[ On 17 June the M01 18.00z & 20.00xz TX’s were sent by the same operator and had similar characteristics - which poses the question “from the same site ??” ]

Tues 1	8 June	17.02z	5074kHz	call 074
Thu 3	10 June	17.02z	5074kHz	call 074

M51

Currently become very active again

Popped its’ head up again on 31 May, 11.00z 6941kHz. Then another “super marathon” followed, first caught at 15.00z on 9945kHz with mssg NR 75 continued monitoring found it still going at 16.10z NR 88, 17.00z NR 02, 21.00z NR 43 and at 06.00z 1^st June it was still there with mssg NR 38, eventually ending at 06.15z

GD comments -

“from past experience of the average mssg length, and assuming it had been going all night, it had sent 179 mssgs !!!

Who is going to sit writing these gps down for a minimum of a 15 hour stretch ???, I cannot understand these very long sessions, but at least keeps GCHQ occupied”.

[Makes one think just what the purpose is :- ED]

On Thu 24 June it was i/p at 17.45z and still going at 06.00z on Friday.

M55

Still usually on its’ Tue 13.00z slot, 12150kHz, with rather weak summer sigs in Europe, but was not logged/heard on 22 June, “will we ever log a message from this one”, remarks GD.

M87

hand, cut. (Mainly heard by IB)

Wonder where the “482” call has gone, not heard since Oct 03

M93

14367kHz, despite intensive monitoring of this freq and regular band searches there have been no loggings, possibly our “special event” comment in Issue 22 was correct, however the CW team will continue to keep an eye on the freq - just in case.
