Slavic stations

Onto the Slavic Desk’s chart and review, followed by the logs:

Chart 19

M10, S10d and S17c from 15^th May, 2005

Compiled by the Slavic Desk

Freqs ± 2kHz

Activity Designations:

• R: Regular transmissions on the time and day shown weekly
• I: Irregular transmissions on the day and time shown
• ALT: Regular transmissions on the day and time shown, but on alternate weeks.

M10e/M11 Schedules as from

Monday 02/05/05 to Friday 06/05/05

Monday 30/05/05 to Friday 03/06/05

Monday 27/06/05 to Friday 01/07/05

Chart 19 above is from 1^st May and will continue until 31^st August 2005. As previously quoted minor changes may occur each month. The 1^st September change will be more comprehensive.

The past 2/3 months has seen ALT schedules changing transmission weeks several times. A number of these schedules needed to change together in order to keep up to the repeat message procedure, including the two sets of 1700 schedules which have now combined to operate on the same week, albeit every other week.

Since 1^st May two schedules have changed one of their frequencies. The 1410z from 5027kHz to 7380kHz and the S10d S0600z from 6782kHz to 11417kHz, brought to my attention by - -?- - [Thanks].

A report has also been received of S10d sending at 1920z on 13502kHz. This has not been charted as I have been unable to confirm it.

The S10d 1855z schedule still remains without any classification on ‘activity designation’ due to inconsistent reception. A number of other happenings this period lead me to a number of observations on M10/M11/S10d.

M10 is a Czech network using four, or more, transmitters. It does not always use ICW. The 0535/1630z transmissions are in MCW [the modulation being keyed – not the carrier].

During the period of this report other MCW transmissions are as follows:

After the separation of Czechoslovakia into the Czech and Slovak republics, triplets have changed. The Slovak system uses 111. The Czech system uses 222, 333, 444, 999 and 777. The 444 triplet was used on the 1520z S10d schedule on Saturday 04/06/05.

I cannot say with certainty which transmissions use parallel frequencies and which do not. With a watch of say six operators one might have a chance. A prime example is S17c with only a seven minute transmission.

ID’s have been called into question; I suspect the 4/5 figures have been Slovak with Czech using the more common three figure 555. The others used may have special significance. With reference to other parts of the procedures, why is the DK sent less often than the ID and GC? [Answers under double seal please].

We now move on to the repeat message procedure and the alternate week programme.

Comparison with procedures previously published with chart 16 [Newsletter 25] show very little change, however schedules 0150 and 0840z have not been found, but believed to be active.

It should be noted that both sets of 2200z schedules are not fixed in the repeat message procedure and may act independently.

M10 Repeat Message Procedure [RMP]:

S10d Repeat Message Procedure [RMP]:

Alternate Week Programme

• Sunday 5^th June to Sat 11^th June 26, 2005
  Sunday 19^th June to Sat 25^th June
  0340, 0800, S0820, 1200, 1340, 1610, 1700, S1820, 1900
• Sunday 12^th June to Saturday 18^th June
  0840, 1140, 1440, 1530, 1820, 1840, 1940

From time to time questions are asked regarding the identity of M10, M10e/M11, S17c and S10d. Although I have previously shown the message format of these transmissions it is perhaps time to revisit them.

S17c – a typical transmission:

Female voice [same as S10d] Czech dialect.

Text consists of one five figure group.

Transmissions are daily from 1250 to 1257 approximately and uses the same groups of frequencies on a rotating basis.

Parallel frequencies are not always apparent; perhaps not found.

The details of this group suggest it to be a broadcast transmission and therefore a control information network.

S10d – two types of transmission format:

Single message

555 799 35 [repeats not shown]
799 99 35
Pozor “TEXT”
Pozor 99 35
Konec

Two message format

555 968 39
437 34
968 90 39
Pozor “TEXT”
Pozor 90 39
437 94 34
Pozor “TEXT”
Pozor 94 34
Konec

M10

This station has a single, two and multi message format.

The construction of the single and two message formats are much like those shown above for S10d. As Morse is used ‘Pozor’ is a double break, -···- -···- or = = as it is usually written. Konec is replaced with 0 0 0.

A single message would appear as:

whilst the two message format obviously appears as:

The Multi message format which is different from others is the 0535 repeated 1630. This transmission is in MCW.

The ID’s are always the same.

[repeats not shown]

This is an ideal Morse practice transmission as each message is sent progressively faster, although the procedural call and message preambles are always at slow speed. I had always believed the IDs were solely used on this transmission but the 1800z on Thursday 4^th November and 1720z on Friday 17^th December 2004 both used 571 ID. See NL26 of January 2005.

M10e/M11

[repeats not shown]

Very slow sending on a four week cycle.

Five figure groups, transmission lasts 26 – 27 minutes.

Voice equivalent S10e has not been heard for 18/24 months. Message repeated from Monday to Friday inclusive.

I conclude this period’s offerings with thanks to PLondon for his early morning perambulations and to those around me for their understanding and patience whilst I put pen to paper.

Is it Sod’s Law or Murphy’s Law? Having finished the chart and other writings this morning, Wednesday 22^nd June I at last hear the 0830z schedule. I have been listening all this period on the higher frequencies and it appears after the paperwork is finished!

No doubt the editor will be able to slot it in [I did – DoK will be pleased to learn that whilst he strived at this yours truly was sculling around a Rotorua Hotel enjoying pumpkin soup and plattered John Dory].

Unless there are major changes I do not anticipate further writings until after the 1^st September change.

Any Questions or Comments on this review via the usual channels please.

DoK 22/06

Freq Change [already!!]: Wed 1900z from 8143 to 7475kHz

[Tnx for your efforts Derek].

S06

See AnonUK’s Chart shewn previously

In the last issue PoSW mentioned that the  S06 1700z + 1800z schedule heard for several years seemed to have gone; HFD wrote in to simply say: “That's not true: 03/05 1700z 6805, 1800Z 5370, 04/05 1700Z 7820, 1800Z 6840”

HFD then offered this ‘corrected’ chart:

Thanks HFD!

Regular S06 schedules include the Tuesday 1630 + 1730 UTC and Tuesday 1850 + 1950 UTC tranamissions, along with the second and fourth Saturdays in the month 1600 + 1700 UTC, always with call "724"; this has been a four minute "no message" for ages now. Also on the second and fourth Saturdays is another 1600 UTC S06 which is always "890 890 890 00000", was on 6,923 kHz throughout the winter and spring months, moved to 6,772 on 11-June, exactly the same as in June last year. And then there is the Wednesday 0700z S06, on 14,580 kHz in May and June; on the few occasions I have been at home to hear this one the signal has been strong enough but the speech always distorted. [Tnx PoSW]

Gert has produced an interesting and informative chart that shews activity for the year to date, with comment:

Then moves to a chart he has produced with input from AnonUK and RNGB – thanks all concerned.

Tnx Gert [constructed with input from AnonUK and RNGB]

S10d

S10d schedules are much as in the same month in previous years and as listed by the Slavic Desk and follow the usual predictable format with a few noteworthy exceptions. Schedules running in June include the following;-

[Tnx PoSW]

A variety of monitors have noticed loud tones occurring during transmissions from Betty. It has occurred in those below marked with *

S11a Cherta

See AnonUK’s Chart shewn previously

S17c

As far as Great Britain is concerned 6758kHz is not a good frequency for the interception of this station. We suffer from heavy tty/data interference. We would be most grateful to receive logs of those that can hear this station on this frequency – please state your QTH sensibly. Germany would not be really helpful – Berlin, Germany would.

Please post your logs to ENIGMA 2000. Thanks

Irrespective of the horrible tty/data QRM MoK manged to offer:

Both AF and HFD were able to hear this station and sent the following:

Spanish lady: V02 and variants:

The Senorita from Havana has become somewhat unreliable in recent weeks; most of the long-standing transmissions heard in the UK early morning can no longer be counted on to appear every week as used to be the case.

[Tnx PoSW]

V02c schedule from MS:

V07

Only report this time, from RNGB:

V13

In message 4573 dated 05/03 Ben Mesander wrote,

"For a while, V13 seemed to have timeshifted into slots where it was not possible to hear it at my QTH. It seems to have resumed at least some skeds that are possible to pick up in the western US. Check around 1100utc-1500utc on:

• 8300.0 kHz
• 9275.0 kHz
• 9725.0 kHz
• 11430.0 kHz
• 11433.0 kHz
• 13570.0 kHz
• 13650.0 kHz
• 13750.0 kHz
• 15388.0 kHz

Note that some of the above freqs are in error, but since it's been so many years since I monitored this station I can't remember the ones that are "real". [Tnx Ben]
