6700kHz hosted a regular pip and heard by ugopetrus who timed the interval as 15.11s. Observations turned up a strong data signal at 0612z 17/09. The origin was thought to be Military following the interception of traffic between KIN470 and M[?]L - either MQL or MKL whilst perusal of records showed the frequency of 6697kHz as being correct for MKL.

Another freq that came to scrutiny under they eyes of DoKent was 5020kHz [home of M10E] 0835z 24/09 when he heard 'Charlie 22 [weak], Bravo.' [LSB] DoKent asks if this was an exercise. Records at E2k suggest that the freq was one used by Canadian Military in the past.

JoA's 1T2B is now designated XTB.

AnonUK alerted e2k to 14896kHz, 1220z, 12/10 where there were some very strange very low tones.

Backwards music station (XM)

There seems to be some confusion concerning the Control List ident for this oddity. It is XM, not BMS or as lately stated, XW.

5435kHz 0253z 09/09  
  0448z 27/09  
  0200z 29/09 [AM (on for hours and hours)]
8086kHz 2308z 12/10 via 'E'
8983kHz 1951z 07/09  
9010kHz 0441z 03/09  


Carriers [Blank ]

'E' Great Britain, has heard open carriers up in the afternoons of September on freqs of 6171.5, 10299, 10827, 15055.6kHz .

Like 'E' 'ugopetrus' reported the 15055kHz carrier as being heard on 15055kHz 16/09 to 17/09. He reported it via group. Various listeners have reported it as very strong. It was still audible 0725z 29/09.

E2k, E and ugopetrus would be grateful to receive any input, via these pages, as to their origin and purpose. 'E' noted that they were just left open and that 'no rtty etc heard.'

On 19th October PoSW wrote:

At 1514z on 9219kHz an S9+ carrier with typical E05 background noise on a known E05 frequency. A check on other frequencies known to be used by Cynthia currently and in the recent past found similar carriers on 6891, 6950, 6970, 7585, 8085, 8110, 8125, 10527, 13450, 13996 and 16090kHz. Twelve frequencies in total. 6891 & 8110kHz were suffering from severe XJT, jet QRM but there was none on 13450kHz which normally has this type of interference when used for the Monday to Friday 1200z transmission. Around 1530z an audio tone came up on all frequencies - except 6970 which remained a plain carrier with background noise. This situation prevailed for a long time - I kept a receiver on 9219kHz and checked all the other frequencies occasionally. At 1622z, over an hour after first noticed, 9219 went off and a quick tune around found all the others had gone QRT too.


Look around 5495//5505kHz as the crackle and Shanwick Air Radio battle for the frequency. [See p25 Issue 11]. Reported by AnonNI 2020z 12/09


These can be heard with some regularity on: 5320, 5600, 6420, 6880, 7040, 7050, 7070, 8320, 8340, 8515, 9360,10280,10470 and 13410, 16176kHz.

Mazielka (X06)

From E:

14419kHz 1002z 15/06
16227kHz 1716z 25/09
17463kHz 1617z 14/10


From RN UK

11413kHz 1800z 04/10


From Gert:

16025kHz 1400z 16/09


From PoSW:

6-Sept-02 Friday 1813z 9,080 kHz strong signal, tones stopped and carrier went off just after 1824z; listened for a couple of minutes, nothing further heard.
7-Sept-02 Saturday 1843z 14,430 kHz close to a strong "Jet", tones stopped 1854z, carrier went off approx. 25 seconds later. Listened until 1857z, nothing further heard.
  1933z 9,067 kHz X06 again, tones stopped in mid flow and carrier went off - as though someone had pulled the mains plug out! - just before 1939z; listened for two or three minutes, nothing further heard.
23-Sept-02 Monday 2133z 8,081 kHz strong signal, tones stopped 2140z; carrier stayed on and after about a minute went into FSK mode. I quickly fired up my old RTTY decoder and the printer started printing columns of 5 letters, as noticed with some other X06 transmissions in the past.
8-Oct-02 Tuesday 2116z 8,102 kHz severe QRM from CW "VVV DE 4XZ 4XZ = =" Israeli Navy?; tones stopped about a minute after being tuned in, nothing further heard.


8105kHz 2000z 02/10 via Jochen, Marburg


In writing up his notes for his analysis of S10D DoKent encountered X06 on 09/10 as follows:

1618z 12226kHz  
1623z   6-note musical tones [Checking all current frequencies] - confirmed X06


On 16/10 DoKent again encountered X06 on 7745z and noted:

7745kHz 16/10 M10 [MCW], carrier on 1615z, message a repeat of Sat/Suns sending.


1618z Same musical tones as per X06, off at 1624z with carrier down at 1625:30z

Having encountered X06 on two frequencies involved with the S10D M10 series of transmissions DoKent raises the valid question, 'Is X06 really Russian or is it more involved with the Czech?'

S28 [formerly XB]

It buzzes away on 4625kHz.

www.geocities.com/uvb76 has been updated

S30 [The Pip]

Continues to dominate 3757kHz in the 80M band.

Slot-machine (XSL)

XSL is heard on 4152.5, 4231, 4290.5, 6249.5, 6416.5, 6444.5, 8312.5, 8587.5 and 8703.5kHz. USB mode

Still being heard in US, Oceania and like areas. E2k would like to receive details of any observations made in Great Britain, Eire and Europe please.

11222kHz 0643z 16/10


6702kHz and 15020kHz were NRH at 0643z 16/10

XTB [One tone, two buzzes]

JoA's 1T2B has been heard again by JoA on 27/09 who writes:

Suggestions as to the purpose of this oddity would be well received!

Wopwop (XWP)

The original XWP seems to have disappeared from its scheduled disturbance of the ionosphere but there are echoes to be heard:

From JoA:

9255kHz 2030z 26/09 [poss XWP ended 2040z]


JoA who writes:

Frequency checked now : 9258kHz 2020-2040z F.27/09. This wopwop was interfering with reception of E03 on 9251kHz.

From E:

16172kHz 1516z 28/07 Loud sigs
