Hello spooks,

I'm a member of the ARRL intruder watch system.  We monitor the ham bands
for non-ham interference.  Over the years I've logged several what used to
be called "single letter beacon" signals.  On the 40 meter band there are
several of these still active.  Here is a list of them:

7002 Khz     V beacon  still active
7039         C beacon  still active
7038.8       P beacon  not active recently
7039.2       F beacon  not active recently

The group around 7039 is known as a "beacon cluster".  It isn't know what
the purpose of these beacons are.  They are assumed to originate from Russia.

There is also a number transmission on the 40 m band.  On 7019 reduced
carrier LSB there is a slavic sounding 5 number group transmission.  Heard
Thursday mornings around 1100 or 1200 UTC occasionally.

I know Ary is around here somewhere, but Ary Boender was able to confirm last year that these are Russian Navy channel markers. If you look back through some of the past newsletters on the WUN website you will find more details. Ary's July, 95, and Feb., May, 1997 UTILITY ROUND-UP columns I know had information. Confirmed markers have been: Channelmarker 'F', Vladivostok Channelmarker 'C', Moscow Channelmarker 'L', St.Petersburg Channelmarker 'P', Kaliningrad Channelmarker 'R', Ustinov Channelmarker 'S', Arkhangelsk Channelmarker 'V', Tashkent RD Rick "RD" Baker CommConf Listening to the ute's from NE Ohio, the USA Contributing Editor Pop'Comm, 'Communications Confidential' column "RD's" Utility Station page http://www.concentric.net/~Commconf ---

No, I have not updated the article in a long time. From that article all that wasd known at the time was that the USN claimed them. There was no word as to where they were registered. I'll have to modify and make a note of that. It still does not explain that one tied between the trees though, or others that have been found in similiar forms.

Hmmm. I am hearing the "D" beacon on 6550Khz here in Tennessee at only 0030 today. Pretty strong too to be heard on my puny antenna assemblage and R-390A. Can hear it on the DX-440 as well with the whip antenna. Not much else heard in the 6 Mhz range right now either, so it is one of the first non-SWBC signals of note that has popped up tonight. Tom

That's right! The SLBs/channel markers/cluster "beacons" are back! My sources indicate frequencies on or around 5154, 7039, 10872, 13528, and 20048. Most of these are clustering. No data heard yet.

Hi Spooks, Below are presented three known standard voice message formats of the Russian military HF channel marker stations (Enigma XX - The Pip, XB - The Buzzer, "R") - all live, non-computerized, mostly male voices, repeated twice, in Russian language, real examples: XX (The Pip), 3757//5448 kHz, Rostov-Volgograd area (?), at different times: In Russian: English translation; "Dlia 854 032 471 331 629 008 " For 854 032 471 331 629 008 Kak slyshno? Priyom." How can you read me? Reception." "R", Izhevsk, Navy, 3194//3321//4325 kHz, usually on the hour, regular schedules: "Rotor-35, ya - Plavets-41. "Rotor-35, I am Plavets-41. Reskript: 22 80 39 90 Rescript: 22 80 39 90 Moskovskoye vremia 0 chasov, 2 minuty. Moscow time 0 hours, 2 minutes. Priyom." Reception." XB (The Buzzer), 4625 kHz, Moscow area, extremely rare: "Ya - UVB-76. "I am UVB-76. 18008 18008 Bromal: Boris, Roman, Olga (...) Bromal: Boris, Roman, Olga (...) 742 799 14" 742 799 14" The purpose of the control messages is to check a readiness of operators at the receiving (network) stations. The received message content, or a special answering message, must be repeated back on the return link - HF, terrestrial MWL, telephone line and/or satellite link. In the cases of XX (The Pip) and "R", the final message word "Priyom" ("Reception") means that the station is waiting for the quick answer.

In a few recent postings Rimantas gives the Pip's frequency as 3757 kHz, and indeed a couple of days ago I succeeded in hearing a voice message (however by an OM and not a YL, as Rimantas says) and on 3756 kHz. Moreover, whereas 3756 kHz is quite strong here (North of Amsterdam), I hear nothing whatsoever on the other frequency indicated (5448). In normal circumstances 5448 ought to be stronger here, though of course the signal may be aimed in another direction. Anyway, could anyone confirm the frequency of 3756 (instead of 3757) and the OM (instead of YL)?

Hi Frank, They use both YL and OM voices, it depends who is on duty at the message time. 3757 kHz is a daytime frequency, they do not operate both channels in //, and parralel xmission is very rare event.

If you zero-beat the "pip" sound itself, it's around 3757. However, I don't think this is a CW transmission, but rather a USB transmission of an audio signal; there is a reduced carrier on 3756, so using the USB standard that becomes the "nominal" frequency. What time of day did you hear the voice transmission? Did you record it? What was the language, Russian? I recently returned from several-week trip to Moscow. The Buzzer (a.k.a. Foghorn) is heard there at S9+20db 24 hrs/day with only slight fading. Reception of The Pip wasn't as good, varied a bit, and was generally better in the morning. In addition, there is one more similar station which I call The Squeaky Wheel on 5461.5; its reception also varied and was better in the local morning hours, possibly indicating a site to the general west of Moscow. Mr. Pile on the irc #monitor group turned me on to this one. The Buzzer and Pip are both easily audible here in Florida, but I've never heard The Squeaky Wheel here even when Pile had it strongly in Finland. While in Russia I also noted the disappearance of the cluster beacons; they were audible when I arrived in mid-June, but not so the last time I checked in early August. Incidentally, the "C" beacon, supposedly Moscow, didn't come in all that well at my location in the northwest of the city; it tended to be weak and fade considerably. The time station RWM exhibited similar propagation though. "S" was generally the easiest to hear, supposedly from Murmansk I believe. I also heard "R" on CW on 3195, running parallel with A2 mode (carrier + tone) on 3321 or 7550 at different times; "L" was heard while I was in Peterburg on 3335, also A2 mode. I don't know whether these disappeared along with the cluster beacons. In both Moscow and St. Pete I heard local A2 mode beacons in the middle of the medium wave band, using 2-letter callsigns. I presume these were aeronautical, but does anyone on the list know for certain, and why they would be here instead of the LW beacon band? dc ----------------------------------------------------------------------- David E.

On a holiday trip to the German Baltic coast in 1995 I noted also two letter call signes in CW on the M.W. Band. After some disussions, one person told me that it might have been Harmonics (highly unlikely, considering th low power output), and another guy said that beacons are to be there up to 900 kHz. I am a bit confused about this, but the latter seems possible. --- Submissions should be sent to spooks@qth.net To unsubscribe, send "unsubscribe spooks" to majordomo@qth.net

Hi, as fas as I know these NDBs in countries of the former USSR (and Warsaw Pact too) are located at military airports. They were quite well audible in the night on frequencies up to ca. 1300 kHz some 10-20 years ago. Now it seems the number of them is continuously decreasing. We had one such NDB (Dobrany "DR" 822 kHz) near my home town of Plzen (Pilsen) in the western part of the Czech Republic. Some 3-4 years ago this NDB has been retuned to 398 kHz and its call changed to "D".
