Selected voice stations

Frequencies preceded by 'c' have been taken from an analogue receiver.

This issue we see some time devoted to S17, a station that had not been widely heard until AnonUK discovered it sending on 21/02. We are attempting to discover its habits and all input is requested via the usual routes please. It has not been heard since 08/03. Keep your ears open for this rarity!

E05

C writes,"Although I don't seem to hear many of these there was a most unusual transmission on SUN March 10th at 1800z. The usual 11072 and 13465 kHz transmission was noted with 'call 351' count 80. Tuning around I also noted the same transmission on 9090 and 11526 kHz, I cannot remember ever hearing a standard E05 message on 4 simultaneous frequencies. Was this a vital message, a mix-up at the transmitter site ? A new anti-jamming ploy for when 'Gulf War - The Sequel' starts ?"

PoSW adds, "E05 continues much as before except a new schedule on Monday 8 - April on 6,950 // 7,585 kHz which must have started at 2100z and needs further investigation! The weekday 0800z transmission is still on; I was last able to check the 5Fs on Easter Monday and they were still the same as noted just after Christmas. Also, the Monday and Friday 2200z transmissions on 9,219 // 10,527 kHz have not been on since late February; this vanished once before in early January then re - appeared later in the same month but now seems to have gone for good. The Saturday 1400z E05 on 18,617 // 19,622 kHz continues to be erratic, often vanishing for a few weeks and then re - appearing."

Of the E05 210/100 messages, PoSW writes, "Cynthia is really going over the top with this 210/100 message; the first noted on Mon 08/04 at 2100z [6950//7585] has been on everyday, including Saturday and Sunday unlike the longer standing 0800z 10527/13996kHz and 1200z 13450//16090kHz 210/100 which are Mon to Fri only.

Also an anomaly was noted with this 2100z sending on both Sat 13/04 and Tues 16/04: On both days there was a strong transmission in progress when checked at approx 2115z on 7585kHz but nothing on the usual parallel 6950kHz. A check of other frequencies used by E05 in the past found Cynthia on 5850kHz on both occasions. This was only just detectable under a very strong BC station, since 5850kHz is inside the 49M BC band."

As if all this wasn't enough there is another sending of the 210/100 message at 1900z on 8085//9129kHz first noticed Friday 12/04. The carriers being noted warming both frequencies up around 1840z. This too has been on every day, including Saturday and Sunday. [Tnx PoSW]

E06

There was a dramatic drop in activity of the E06 English Man station during March; the usual Saturday 1230z and 1330z showed up on frequencies in the region of 15,880 kHz (1230z) and 13,520 kHz (1330z) on the 2nd, 9th and 16th of March but there was no sign on the remaining Saturdays, the 23rd and 30th. I think these were the only times I have looked for the Saturday E06 on a known frequency schedule and found no trace. E06 was back on the first Saturday in April on 14,860 kHz and 12,190 kHz. [PoSW].

Gert and AnonUK wrote in to advise us that Sat/Sun freq's for E06 for April are: 8080kHz 1230z 14860kHz, 1330z 12190kHz

Gert observes that the Thursday/Friday transmissions [6785/7785kHz] may only occur in weeks 2 and 4 each month. [Note last group 15890kHz 16/03 transmission].

Gert also reports a different E06 transmission [8080kHz 2010z 31/03] he heard starting as having "a strange intro starting at 2010z on 8080 kHz (sun 31 march 2002): 102 102 22585 for 5 minutes; 537 40 40 followed by 5 fig groups, each repeated, starting with 04121ending 00000."

Onto PoSW's observations:

E07

Gert advised us that the March Wed/Fri morning frequencies remained the same:

whilst the mon/wed evening freqs were:

Gert later confirmed the April freqs as:

Some gaps are filled in by PoSW's E07 log:

• 22-Feb-02, Friday
  0650 UTC, 9,368 kHz, E07 with what must have been the last of three sendings, calling "913 913 913 1", DK/GC "182 79" x 2, strong signal, over - riding BC station on nearby frequency.

• 11-Mar-02, Monday
  2121 UTC, 8,185 kHz, E07 English Man calling "418 418 418 000", strong signal, stopped just after 2122z.

• 18-Mar-02, Monday
  2140 UTC, 6,817 kHz, E07, "418" and "1451 108" again, strong signal but with QRM from a RTTY type signal and the "Wop wop".

• 20-Mar-02, Wednesday
  2100 UTC, 9,420 kHz, E07 English Man with "418 418 418 000": inside the 31 metre band and an S9 plus many dB broadcast station suddenly came on the air at 2101 and 30 seconds; it would have been impossible to hear anything at all of E07 if this BC station had been on at 2100z. 2120 UTC, or rather 25 seconds before 2120z, E07, "418 418 418 000" again

• 22-Mar-02, Friday
  0642 UTC, 8,103 kHz, E07 English Man in progress, strong signal, ended with "000 000" just after 0646z.
  0650 UTC, 9,368 kHz, E07 again, "913 913 913 1", DK "3481", unable to make out the group count due to severe BC QRM; E07 seems to like lurking inside the 31 metre broadcast band!

• 27-Mar-02, Wednesday
  0642 UTC, 8,103 kHz, E07 in progress, strong signal, ended "000 000" after 0646z.
  0650 UTC, 9,368 kHz, E07, "913 913 913 1", DK/GC "3481 171" x 2, stronger than when heard on Friday, above, over - riding BC station.

• 1-Apr-02, Monday
  2020 UTC, 12.217 kHz, E07 English Man, "920 920 920 000", strong carrier but modulation level low.

• 3-Apr-02, Wednesday
  2000 UTC, 13,922 kHz, E07 English Man, "920 920 920 1", DK/GC "325 34" x 2, strong carrier, mod. low.
  2020 UTC, 12,217 kHz, and "2040 UTC, 11,028 kHz, repeats of "920" and "325 34", same frequencies and call used in April last year. ©PoSW

E10

ML sent an interesting snippet via spooks concering E10 operations:

"The High Court of Justice (HJC) today rejected the Telecommunications Law amendment making the Arutz 7 radio station legal. The HJC ruled that the amendment violated freedom of occupation and was therefore null and void."

Ary followed with this rather interesting fact, "There are rumours -ever since Arutz 7 started- that they are funded by Mossad and that numbers transmissions originate from the ship. DFs from Cyprus and W.Europe pinpointed numbers transmissions to a spot somewhere off the coast of Haifa a couple of years ago. I wonder if there is any truth in this story. I wouldn't be surprised........" Neither would E2k!

Onto the E10 log from BMDartford.

For The Month of February 02 in Freq/Time/Date/C/s/G order [all times Zulu]:

General comments

The month of FEB 02 as heard in Dartford qth proved to be quite good, with a number of the lesser-heard stations being picked up, mainly during the mid to late evening period as conditions permitted.

These ID's were: CIOA2M2C4 HNCZ HNCI HNC1 ABC ART1.

The top five most heard common ID's for the month of FEB are, 1.CIO2 2.VLB2 3.FTJ 4. JSR 5. KPA2

For whatever reason I have yet to hear KPA transmitting since when I first started monitoring in Nov 01

The honour of the smallest number group transmitted goes to ULX group 8, sent on two occasions the 24th & 26th of Feb coupled with a Group 54, maybe the same messages being resent . The longest being G112 sent by ART 22 Feb.

For The Month of March 02 in Freq/Time/Date/C/s/G order [all times Zulu]:

CIO2 was most busy on the airwaves saying nothing during the month, and were heard on five frequencies 7Mar 3.230 14Mar 4.780 and regularly on 4.360, 5.339 & 6.912 simultaneously. CIO is also using the last three freq. The remainder of the common c/s seem to be using their one or two frequencies, with the odd exception.

E10's rare network HNC was again heard this month, on 6.575 this time as HNCR & HNCS on the 21^st & 24^th of Mar but as in Feb nil messages.

VLB2 is also very much in evidence and has used six different frequencies since Nov01 these being 7.065 6.930 5.170 4.780 4.015 4.360. I have not heard VLB since 05Feb. VLB3 was heard on the 23^rd & 24^th of this month on 5.170 at around 21:00hrs, but true to form no messages.

Top five senders CIO2 MIW2 VLB2 ART JSR, Longest Message ART (149)

Shortest Message FTJ (G8). ©BMDartford [Tnx BM].

C adds these thoughts : "Activities continue and some of the Low Traffic Stations seem to be active. CIO was noted on SAT February 2nd at 2052z on 4360kHz sending CIOA2C2M4 //5340 kHz. CIO was also heard on THU April 4th at 1839z on 6912kHz with a repeating loop message of just 16 groups. KPA has also been active with short messages and I recently noted PCD on 6498kHz at 1900z under severe QRM of an 'XJT' transmission, I did think PCD had left this particular frequency." [Tnx C]

E11

With its simplistic message one would have thought E11 would commence on time. Shoddy preparation was noticed by the monitors as E11 was late on parade at the beginning of March. [Give the op. a 252]!

E17

G04

PLondon reports this station as:

A sound sample [.wav] was placed on the Group site.

Observations made on Sunday 11/03 did not reveal any G04 activity between 2000 and 2200z resulting in the station being marked up as NRH for that day.

Freqs previously reported as follows [Date: 2105z freq 2135z freq]:

01/00:3440 3340,02/00:3920 3820,03/00:4520 4420,04/00:5210 5310,05/00:4830 4930,06/00:5220 5320, 07/00:5360 5460,08/00:5320 5420,09/00:4760 4860,10/00:4580 4680,11/00:4270 4370,12/00:4110 4210,

01/01:4120 4220,02/01:4280 4380,03/01:4750 4850kHz........not reported since.

Any observations made in April should take into account the time change to 2005/2035z

NOTE: Freq used 03/2002 same as that recorded for 03/2001.

G04 was reported via group by DofKent and AF in April on the First Thursday as:

Above sending was also reported by JoA/AnonUK and, by pager, Angus of Strathclyde.

E2k notes that it is 5 mins earlier on both slots for April, but virtually obeys its previous time change history to ensure it is sent at same time. [As March's observation April's frequencies match those used during April 2000]. Certainly looks as though G04 is a first Thursday of the month station and that May's freqs could be 4830/4930kHz. FIRST THURSDAY IN MAY IS 2^nd May!

G06

The G06 German YL schedule continues on the first Monday of the month although I could not find it on the first Monday in March (4th) ; I wonder if anyone reported it? It was on the next day with a full message transmission, a next day repeat being usual for this one when a full message is sent. Both transmissions were strong signals and stuck out like the proverbial sore thumbs. This G06 has broken the routine of showing up on the same frequency as used in the same month a year earlier which makes finding it a bit more difficult; even so I cannot understand how I missed it on Monday. The transmission on the first Monday in April was no problem to find although the frequencies of both sendings were not the same as those used in April last year. The Friday 1930z G06 appeared on the 15th and 29th of March with a crafty change of frequency on the 29th which almost fooled me. By the way I have never been able to find a repeat of this Friday Fraulein, not an hour earlier or an hour later or on the Thursday before or the Saturday after which is not the usual routine for this family of stations.

• 1-Mar-02, Friday
  1930 UTC, or rather 1929 and 20 seconds because it started early, 4,792 kHz, G06 German YL . Surprised to find the Friday Fraulein on this frequency because in March last year she moved to 5,444 kHz. Carrier was up at 1842z, numbers 1 to 9 in German repeated several times and several minutes of audio tone to warm the frequency up. Call "Vier drei sechs", DK/GC "Funef acht acht" x 2, "Vier seben" x 2, strong signal with lower sideband well suppressed. Ended 1944z

• 4-Mar-02, Monday
  I could find no trace of the first Monday in the Month G06 German YL; I expected her to show up at 1900z on 9,050 kHz, repeated 2000z, 7,610 kHz because these were the frequencies used in March last year. I also tuned up and down the band in case she was on another frequency but found nothing!

• 5-Mar-02, Tuesday
  1901 UTC, 8,035 kHz, G06 German YL; not on her expected frequency, I wonder how I missed this yesterday. This was a very strong signal, impossible to miss. Call - up already in progress when tuned in, "Drei null acht", DK/GC "Funef vier seben" x 2, "Eins sechs" x 2, short message, perhaps the shortest ever from G06. Ended 1907z with DK DK GC GC and 5 x "Null", lower sideband suppressed.
  2000 UTC, 6,785 kHz, repeat of G06 "308" and "547 547 16 16", carrier with tone noted 1950z.

• 15-Mar-02, Friday
  1933 UTC, 5,445 kHz, Friday G06 German YL; she has shifted frequency - was on 4,792 kHz when last heard on 1 - March but has now moved to similar frequency to that used in March last year. I had been tuning around 4,792 and had just made a note in the log to the effect that there was no sign of G06 when I decided to check 5,445 - and there she was calling "Neun vier seben"; must have started late as the DK/GC was not reached until 1935 and 30 seconds, "Drei sechs acht" x 2, "Vier neun" x 2, strong signal with lower sideband well suppressed.

• 29-Mar-02, Friday
  1929 UTC, 5,446 kHz, the Friday night G06 German YL; started a minute early according to by MSF Rugby controlled clock! Carrier was on at 1847z calling a few numbers in German; the voice here was higher pitched and faster than usual, like a tape running fast. When the transmission began the voice was normal in pitch and speed of delivery. Calling "Neun vier seben", DK/GC "Drei sechs acht" x 2, "Vier neun" x 2 - same as when last heard on Friday 15-Mar-02. Strong signal, lower sideband suppressed.

• 1-Apr-02, Monday
  1900 UTC, 8 PM BST, 9,220 kHz, the first Monday in the month G06 German YL. "Drei null acht" x 3, "Null" x 5, a four minute "No message" transmission, strong signal, lower sideband well suppressed - but when LSB mode was selected on the receiver there were Morse key clicks - could also be heard with the RX in AM mode, but not USB; these were very fast like M24 CW
  
  2000 UTC, 7,680 kHz, second sending of G06 "308 308 308 00000". Very strong signal, carrier with tone noted a few minutes earlier, none of the key click breakthrough noted on the first sending. The Monday G06 no longer turns up on the same frequencies used in the same month a year ago; the schedule in April 2001 was 1900z, 11,040 kHz and 2000z, 9,151 kHz

G07

Another oddity - the G07 voice was noted on FRI March 15th at 1855z on 5445 kHz sending a continuous count from 0 to 9, the transmission cut off at 1901z and no message followed? [Tnx C]

S04

S06

For April AnonUK informs us of:

PoSW's complete S06 log reads as follows:

• 18-Feb-02, Monday 2236 UTC, 5,760 kHz, S06 in progress, good signal, lower sideband well suppressed, ended just after 2243 UTC with "Dva shesht vosyem" x 2, "Pyat tri" x 2 and 5 x "Noll". Same frequency was noted active on Monday 4 - Feb.

• 19-Feb-02, Tuesday 2230 UTC, 5,760 kHz, S06 calling "Syem cheteria deviet" - i.e. "749", DK/GC as yesterday, "268 268 53 53".

• 3-Mar-02, Sunday 1543 UTC, - unusual time to find S06 out and about - 9,065 kHz, call - up in progress, must have started at 1540z, "Tri cheteria deviet", then DK/GC "Adean null shesht" x 2, "Dva dva" x 2. Signal strength about S7, lower sideband well suppressed, ended 1549z.

• 4-Mar-02, Monday 2130 UTC, 8,150 kHz, the first and third Mondays in the month seem to be a regular slot for S06. Calling "Dva syem tri", DK/GC "Cheteria adean deviet" x 2, "Pyat shesht" x 2, strong signal, lower sideband suppressed, carrier with tone noted warming up the frequency at 2117 UTC. Ended 2144z with DKDK GCGC and 5 x "Noll"; carrier did not go QRT but stayed on and an E06 English Man transmission started up on 8,150 kHz at 2200z.
  
  2230 UTC, 6,970 kHz, a repeat sending of "273" and "419 419 56 56", close to the broadcast station on 6,973 kHz - which puts a good signal into the UK in our evenings, sounds like Hebrew so assumed to be Israeli and plays local music together with British and American rock - resulting in a high pitched heterodyne.

• 5-Mar-02, Tuesday 2130 UTC, 8,150 kHz and 2230 UTC, 6,970 kHz, the next day repeats of yesterday's "273" and "419 419 56 56".

• 9-Mar-02, Saturday 1700 UTC, 14,620 kHz, carrier noted a few minutes earlier, S06 calling "Tri pyat adean", then DK/GC "Dva null syem" x 2, "Shesht cheteria" x 2. Strong signal, peaking over strength S9, lower sideband well suppressed.
  
  1800 UTC, 12,210 kHz, repeat sending of "351" and "207 207 64 64". There seems to be an S06 schedule on the second and fourth Saturdays in the month so should turn up again on 23 - March.

• 12-Mar-02, Tuesday 2130 UTC, 10,205 kHz, S06 Russian Man with what turned out to be a two message transmission, although the first was very short! Calling "Syem dva shesht", then DK/GC "Adean null tri" x 2, "Dva" x 2, - a message consisting of two 5F groups! - which were;-
  Adean adean adean adean adean x 2; null null null dva deviet x 2;
  followed by DKDK GCGC, then called "Syem dva shesht" again for a minute or so followed by "Adean tri cheteria" x 2, "Pyat null" x 2 and the second message. Very strong signal with lower sideband suppressed, carrier with tone noted 2117z.
  2230 UTC, 7,720 kHz, a repeat of the earlier "726", DK/GC "103 103 2 2" and the first message, "11111 11111 00029 00029", followed by DK DK GC GC and "726" repeated for a minute and "134 134 50 50" and second message.

• 23-Mar-02, Saturday 1700 UTC, 14,620 kHz, as noted on Sat. 9 - March, call "Tri pyat adean", DK/GC "Cheteria deviet null" x 2, "Pyat dva" x 2, strong signal with lower sideband suppressed, carrier with tone noted 1647z.
  1800 UTC, 12,210 kHz, repeat sending of "351" and "490 490 52 52", slightly weaker than the first sending

• 8-Apr-02, Monday 2115 UTC, 10,860 kHz, S06 Russian Man with "Adean vosyem null" x 3, "Noll" x 5. Strong carrier with tone noted just after 2110z but signal became weaker by the start of transmission. Lower sideband well suppressed, stopped a few seconds after 2114z.

S10E

As expected came up on Monday 11^th March:

Next scheduled appearance expected on 8^th April was heard as:

DofKent informs us that the next appearance should be 6^th May.

S11A

S17

After its discovery by AnonUK on Thursday 21/02 [page20 NL9] DofKent likewise reported hearing S17 the very next day, Friday 22/02.

On Thursday 28/02 a series of rapid tones were heard prompting D0fKent to contact e2k immediately. The observations were [[Cz/YL/3+5fig]:

Further tones around 1118z and another sending of groups were not heard on 7809kHz [on 28/02] until 1255z. [tfb = rapid tones followed by].

Transmission ceased 1346z

Observations by DofKent on Friday 01/03 produced this log from 7809kHz:

Saturday 02/03 to Wednesday 06/03, On watch 1000 to 1200z with NRH.

Despite continual monitoring the signal remains NRH to date. Change of freq, propagation matters, QRT or just sending in a different direction? ©DofKent [TnxDoK]

The S17 format suggested a weekly schedule occurring on Thursdays and Fridays starting around 1015z and possibly again at 1250z with message groupings of 4 sendings, to three recipients daily [01/03 being 688, 351 and 401]. That gives a transmission of 12 actual messages. The actual sendings are preceded by a series of rapid tones and it would seem to end its schedule with rapid tones, the length of transmission being somewhat shorter [?]. Whilst the spoken ordinals are of 'Slavic' origin the accent is somewhat different to that heard on S10E and S17C. To learn more of the station's possible location we need to identify the varied inflections. The signal strength is fair to good in the SE of England.

[Thanks to DoK for his Cz expertise and to AnonUK for finding this stn and supplying his log of initial results].

Monitors did not hear S17 come up on 07/03 or 08/03. All that was heard on 08/03 was a very strong carrier. [This carrier appears to be present daily, as does some side-splatter from Radio China [?]

S17C

As from 01/03 DofKent discovered that S17C had returned top its old haunt of 8190kHz

The signal from this station was on USB on 10/03 and was a very poor signal. The USB signal on 11/03 was very strong. This variation of strength has been noticed before and suggests that this signal is directional and intended for different areas. Has anyone discovered a second freq yet?

V02

Reports from US are:

Whilst our own PoSW in GB heard the following:

• 28-Feb-02, Thursday
  0636 UTC, 8,097 kHz, V02 Spanish YL in progress, strong signal.

• 7-Mar-02, Thursday
  0637 UTC, 8,097 kHz, V02 Senorita from Cuba, very strong signal.

• 13-Mar-02, Wednesday
  0704 UTC, 9,063 kHz, V02, transmission in progress with utility QRM

• 21-Mar-02, Thursday
  0636 UTC, 8,097 kHz, usual Thursday V02 Spanish speaking YL, strong signal.

• 28 Mar-02, Thursday
  - there was no trace this morning of the V02 Spanish YL around 0630z on 8,097 kHz; this has been a fair to excellent signal right through the winter months and into spring but today for the first time there was not the slightest sign.

• 29-Mar-02, Friday
  0704 UTC, 9,063 kHz, V02 Spanish YL, turns up on Good Friday with a strong signal.

• 31-Mar-02, Sunday
  0725 UTC, 6,837 kHz, V02 Spanish YL in progress, good signal, up to strength S9, slight crackling noise, ended 0732z with 3 x "Finale"
  0808 UTC, 9,230 kHz, V2 again, weaker than earlier sending and with background buzz. Ended 0812 UTC with 2 x "Finale". The carrier, complete with buzz, stayed on until 0842z.

• 4-Apr-02, Thursday
  0536 UTC, 8,097 kHz, and again starting up just after 0600 UTC, V02 Spanish YL with a very strong signal; I don't know why she was absent last Thursday. ©PoSW

V02A

V07

14387kHz - large carrier [S9 with PoSW] heard just before 0600z morning of Tuesday 16/04. On the hour, "Tres cero quatro" x3 'Uno' then dk/gc ending at 0615z.

Two further sendings occurred that day:

PoSW observed that V07 used to have a regular schedule based on Tues/Thurs. PoSW checked 0600z 14387kHz and was aware of a poor carrier, due to propagation, and was unable to make a positive identification.

PoSW asks for help with this Spanish station ending with 000 000.

AnonUK contacted E2k 23/04," Can confirm V07 Tuesday 0600 on 14385, 0620 on 16085, Call 304 Null message. I expect third frequency to be 17485kHz." [Tnx Anon].

Note: Call of 304 contains, in order, the third number of the freqs employed by V07.

V08

The V08 Arabic YL showed up on the first Saturdays in both March and April on 6,647 kHz; it shifted by an hour with the start of British Summertime so that in April it still started at 7 PM BST UK time. [1800z]

PoSW adds further info on the Arabic station:

• 2-Mar-02, Saturday
  1900 UTC, or just after, 6,647 kHz, V08 Arabic YL, I last heard this one on Saturday 2 -Feb - 02; carrier with tone noted 1849z, stopped after 1900 followed by the usual Middle Eastern music and then the YL voice. Strong signal but audio level somewhat low. Finished 1911z with more music for a minute or so, carrier with that "High cycle" alternator whine stayed on until QRT just before 1015z.

• *6-Apr-02, Saturday 1800 UTC, 6,647 kHz, the V08 Arabic YL; last heard Saturday 2 - March; the "Attention 123" column in this month's Short Wave Magazine says this one appears on the second Saturday of the month, but it looks as if it ventures forth on the first Saturday. It has shifted by an hour with the start of summertime so it turns up at the same local time - 7 PM in the UK.
  Very strong signal, carrier with audio tone noted a couple of minutes earlier, started exactly on the hour with the usual Arabic music which was very faint. The YL voice was at normal level although a bit clipped and distorted at times. The voice stopped just after 1814z followed by the music for a minute or so, this time at normal level, until approx. 1815z ; 30 seconds. carrier with faint "High cycle" power supply whine stayed on until QRT just before 1819z.

XP

Further to the correction of the XP[H] designation we offer this insight as to our thinking:

The Tues/Thur that we listen to uses tones of 305, 321, 337, 353, 369, 385, 401, 417, 433, 449, 465, 481, 497 and 513Hz. Originally this was thought to be XPH because a similar transmission using lower tones had been heard and designated XPL.[A test transmission from the same family as M10E and S10E. They alternated daily between RTTY, CW and XPL]. The current Saturday transmissions have higher tones [measured by AnonUK] as 814, 844, 879, 954, 992, 1038, 1089, 1143, 1202, 1234, 1271, 1304Hz.

From the XPL sample sent in by AnonUK E2k were able to measure freqs used as 327, 332, 356, 359, 386, 391, 416, 426, 442, 456, 480, 496Hz. The low freq sounds heard are believed to be the product of more than one tone sent between 322 to 582Hz [much like the tones produced by the telephone tones].

One can easily see the predicament here as we try to maintain a separation between the different frequency polytone stations.

February 02 freqs.

Note that last scheduled transmissions were on 28/02 for 21nn slots.

Note that from 14/02 Friday changed to Thursday, XP now due on Tues/Thurs.

March frequencies have indeed changed (-2kHz from those stated on group).[JoA/PLondon] :

ID 168

On 05/03 the 0740z freq was plagued by a SuperDARN [Grasshopper] like transmission. The XP carrier was strong enough to obviate this.

The evening slot freqs were different from the expected 9540/7610/4582kHz and it appears that freq changes are occurring each month.

ID 941

The late XP March schedule hinted at was heard by PoSW:

on Tuesdays and Thursdays in March. Are there other like transmissions throughout the year also?

XPH

March Saturday XPH was sent as:

ID 357

Listed by both PLondon, PoSW and AnonUK 02/03, Anon made this valid comment,'Null Message. Tones so far 1304 Space, 1234 0, 992 Repetition. If the ID is going to be the same figures as the frequencies it will make tone 879 8 and tone 954 4. But this will mean the figures do not run in a sequence of tones.'

Following on from his work outlined above AnonUK has been able to allot numerical or functional values to the nominal frequencies used within XPH:

1304 Space
1234 : 0, 814 : 1, 844: 2, 879 : 3, 914 : 4, 954 : 5, 1038 : 6, 1089 : 7, 1143 : 8, 1202 : 9,
992 : Repeat, [1271 Unknown]

1271Hz remains a mystery for the time being; if anyone has any suggestions as to its function we would be grateful to hear about it. [We suspect a separator to keep decoders active whilst no message is being sent].

Using the above tones one can easily see that the ID for February is 639 and March is 357.

Not only has AnonUK allotted these values/functions but has also proved what appears to be a rather tenuous link with the Morse station M12.

XPH also sends a preamble the same as M12, DK and GC. The March one is 805

Space 131 Space 805 Space 131. It suggested a 131 group message; AnonUK later confirmed the XPH message had 131 groups. [Well done AnonUK].

April's 'known' schedule not yet fully heard. Has propagation seen this station off or is it a totally new schedule? If anyone discovers the new times/freqs please contact E2k via the usual route - tnx.

First report came via JoA:

Since that initial hearing e2k monitors have been unable to discover any mid-morning/early afternoon sendings of XPH.

PoSW makes a rather valid comment, "probably also on Tuesdays." He backed that remark up with a later message, "The full schedule of the Saturday and Tuesday evening XPH polytone transmission is:
1830z 14837kHz, 1850z 13372kHz, 1910z 11648khz. The 1910z sending is prone to BC station QRM but can just be heard with Rx in LSB mode." Excellent work PoSW!

AnonUK monitored the evening sendings on Saturday 20/04, and using his previously derived table of tones found the call up to be 836; the third letter of each frequency. [1910z was believed to be NRH].

AnonUK observed that since we have monitored XPH the call up has not sent this info before.Unless of course it is the evening sendings which are important and the lunchtime sendings reflected that by transmitting the 3^rd letter of each freq used in the evening.

XPL

This rare station [rare to these columns anyway!] was heard by E:

[E, If you have a recording of this oddity could you please send to e2k for some tone analysis work to be carried out]?
