** CUBA. 9545, Sept 6 at 2040 with cohetes at variable rates from the DentroCuban Jamming Command on a frequency which needs no jamming at this hour until República comes up at 2300; meanwhile wall of noise jamming on 9565 against Martí (Glenn Hauser, OK, DX LISTENING DIGEST)
** ECUADOR [and non]. Bandscanning 49m at an unreasonably early hour here Sept 6, and despite hi noise level after getting Mérida on 6104.8 [see MEXICO], I looked for more, and found a signal on 6050 at 2045, also in Spanish, so has to be HCJB`s regional service roughly two hours before sunset there and four hours before sunset here. At 2053 a bit stronger with
choral hymn, amen, 2055 Spanish talk. Hoped to get definite ID and/or characteristic automatic timesignal at 2100 but by then it had faded down and out. A fluky reception.
BTW, a quirk of my FRG-7 (or all of them?) is that in the overlap within each MHz band between about 965 and 055 kHz, there is noticeably greater sensitivity by tuning up from below rather than down from above. Can this be evened out be realignment, and would one even want to? So for 6050 I had a choice of 5 MHz + 1050 kHz, or 6 MHz + 50 kHz. With the former I was getting a stronger signal measuring S9+5 at peak. Best 49m signals at this time were Habana on 6000 and 5965; also barely audible CFRX 6070 and WBOH 5920 (Glenn Hauser, OK, DX LISTENING DIGEST)
** EQUATORIAL GUINEA. Tuned in 15190 at 2111 Sept 6 to find open carrier from Radio Africa. Not unusual for there to be VERY long periods of dead air from this station, so while my attention was focused elsewhere, left this turned up to find out just how long the dead air would last: until 2122, when with never an ID, abruptly started a preacher from North Carolina concerned about the last days and the return of Jesus; good modulation on this one, and he paused briefly to turn off an alarm beeper. So the dead air was at least 11 minutes. Are the Radio Africa operators dozing off, inebriated, stepping out for a smoke or some other important business, or just totally nonchalant about getting the paid-for evangelists on the air? What does pointlessly burning 50 kW for 11+ minutes cost in this poor country? (Glenn Hauser, OK, DX LISTENING DIGEST)
** GERMANY [non]. 11670, Arabic station with good signal, Sept 6 at 2033 with several mentions of ``Al-mania``, soon confirmed with DW jingle. Hmmm, that cognates with Alemania, the Spanish name for Germany, so did the Spaniards get it from the Arabs or vice versa, and why call it something completely unrelated to ``Deutschland`` or ``Germania``? Or is Ger a translation of Ale or v.v.? One might ask the same of the French. O, this is DW at 19-21, 250 kW, 100 degrees via Sines, PORTUGAL (Glenn Hauser, OK, DX LISTENING DIGEST)
** MEXICO. Despite hi local noise level, I minimised it as best I could by closing down several known household noise sources, and boldly commenced to bandscan as low as 6 MHz at the early hour of 2043 UT Sept 6 = 2 hours and 11 minutes after local mean noon, closer to that than to sunset. Yay, bits of Spanish could be heard at a couple signal peaks on 6104.8, has to be XEQM, RASA Mérida. I did not stay on frequency constantly, but often checked in next semisesquihour, heard it no more altho could detect weak carrier when I quit at 2133. HCJB was also poking in around the same time; see ECUADOR; and also UNIDENTIFIED 9600 (Glenn Hauser, OK, DX LISTENING DIGEST)
** ROMANIA [and non]. 9765, Sept 6 at 2039 with roughly equal mix of Castilian and British talk, fast SAH between them of approx. 15 Hz. Looked up later, this clash is between Spain via Costa Rica site and Romania via Galbeni site, the former using 9765 for very long hours and the latter only during this semihour designated for Europe, altho exactly the same 300 degree heading as designated to NAm at same time on other frequencies; can RRI adjust the vertical takeoff angle to optimize for closer or further targets at the same azimuth? (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. Substituting for the ``Available Time Slot`` show on WBCQ 7415, Sunday Sept 6 at 2104 was a repeat of Allan Weiner Worldwide, which he said was // 5110, but that referred to the Friday 2300 live airing. Later in hour, as reception was improving, he was advising pirates not to deliberately interfere with other services, a good idea (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [non]. YFR keeps shifting around different relay sites and frequencies, testing? 5930, weakly heard Sept 7 at 0053 with Harold Droning in English // 7360, both of which have adjacent interference from much stronger signals: 7365 DentroCuban Jamming Command and Radio Martí; 5935 WWCR and DGS. These are both via French Guiana (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 6110, open carrier as I tuned in at 2107 Sept 6, then off after a few sex. Likely VOA Greenville tuning up for Spanish service which does not start until 2300 (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. My 49m bandscan uncovering signals out of the noise level earlier than expected found TADIL-A beeping on 6130, greatly improved with BFO on, Sept 6 at 2107; 5 beeps and then a longer noise/data burst. However, one could also detect briefer noise/data bursts at the end of each short beep (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 7175 at 2101 Sept 6, sure sounded like DRM roar centered here, but there would not be any broadcaster now that it`s a hamband. But it could be Ethiopian jamming against Eritrea, which others have reported sounds a lot like DRM (or could even be DRM used for this nefarious purpose?). But it vanished at 2102 before I could monitor any further. Could also have been ham experimenting with DRM, or would that have been restricted to below 7100? (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. A weak het on 9600 caught my ear Sept 6 at 2036, roughly one semikHz on the hi side, or more like 9600.4. That immediately brings visions of XEYU, Radio UNAM, Mexico City, which when last active a couple years ago was always slightly off-frequency on the low side. But we have no reason to believe it`s back on the air, since the engineer who was trying to keep it on SW moved to another job. What else might be off-frequency here? Not likely Kashgar with its rather new equipment, but which probably provided the other side of the het. Habana not on the air at this hour, for sure. There is really nothing else listed anywhere, so a faint hope remains for XEYU, with further chex called for (Glenn Hauser, OK, DX LISTENING DIGEST)

Dal 1966 il trasmettitore a onde lunghe di Prangins emette segnali orari ufficiali a una frequenza di 75 kHz abbinati all'ora mondiale coordinata. Le informazioni orarie, che sono sincronizzate con un orologio atomico, possono essere impiegate per il controllo di orologi radio e di apparecchiature tecniche. L'emettitore è operativo 24 ore su 24. I segnali orari rappresentano un servizio pubblico gratuito. Il trasmettitore è stato gestito da PTT e fino a maggio 2000 da Swisscom. Successivamente la gestione è passata nelle mani dell'Ufficio federale di metrologia (METAS).
I lavori di manutenzione periodici all'impianto di trasmissione hanno messo in evidenza diversi punti di usura sulle antenne. Dalle perizie effettuate da specialisti indipendenti è emerso che un mancato risanamento delle strutture comprometterebbe in maniera inammissibile la sicurezza e comporterebbe l'interruzione dell'esercizio del trasmettitore.
Il mantenimento in funzione del trasmettitore, attraverso un intervento di risanamento, ha costi elevati che non potrebbero essere compensati dall'attuale impiego ridotto dell'impianto, come è emerso da uno studio esterno che ha anche verificato se il trasmettitore a onde lunghe potesse essere utilizzato per altri scopi o se la sua gestione potesse essere rilevata da altri enti. L'esito negativo di tali verifiche ha portato a decidere la messa fuori servizio dell'impianto per la fine del 2011.
La decisione è stata presa con anticipo per lasciare agli utenti il tempo necessario per sintonizzarsi sul segnale del trasmettitore tedesco DCF77, che ha una qualità di ricezione in Svizzera pari a quella del trasmettitore di Prangins. Oltre ai circa 3600 utenti istituzionali tra chiese e scuole, vi sono anche alcuni apparecchi riceventi come radiosveglie o ricevitori di informazioni meteo che sfruttano i segnali HBG. Molti di questi apparecchi sono dotati di ricevitori compatibili con il trasmettitore tedesco DCF77 e potranno quindi continuare a funzionare senza problemi. La maggioranza dei apparecchi sul mercato è ormai compatibile solo con il trasmettitore tedesco; ciò vale per quasi tutti gli orologi da polso radiocontrollati.
L'ora ufficiale svizzera continuerà ad essere trasmessa da METAS. Sarà inoltre messo a disposizione un server per l'ora (ntp.metas.ch) grazie al quale sarà possibile sincronizzare l'ora dei computer con la scala svizzera del tempo. METAS è l'istituto a cui compete la gestione e la diffusione delle unità di misura in Svizzera, tra cui anche l'unità del tempo, il secondo. Tra i suoi compiti rientrano anche l'individuazione e la diffusione dell'ora ufficiale svizzera. Fino alla messa fuori servizio a fine 2011 sarà METAS a gestire il trasmettitore del segnale orario HBG di Prangins (VD).| Steven C.

A new version of the popular data modes software MULTIPSK has been released which features MIL-STD-188-110A also known as STANAG 4539 or FED-STD-1052
Patrick F6CTE writes:
Hello to all Ham and SWL,
The new release of MultiPSK (4.15) is on my Web site (http://f6cte.free.fr).
The main mirror site is Earl's, N8KBR:
http://www.eqth.info/multipsk/index.html (click on "United States Download Site").
Another mirror site isTerry's:
http://g90swl.co.uk/multipsk/
Multispk associated to Clock are freeware programs but with functions submitted to a licence (by user key).
The main modifications of MULTIPSK 4.15 are the following:
1) Decoding of the MIL-STD-188-110A ("110A") + 110A beacon. This mode (MIL-STD-188-110A/B) is named also FED-STD-1052 or STANAG 4539. It is used mainly by professionals (the text being mostly encrypted) but also, rarely, by Hams.
The 75 bps sub-mode in TX (beacon) is proposed by Multipsk.
Several sub modes (75 to 4800 bps) and two different interleaving (short and long) are proposed. All modes are fixed frequency, except a 75 bps (bits per second) sub-mode which is transmitted in "frequency hopping". It is not decoded in this soft.
The receiver should be in USB mode. The bandwidth must extend from 300 to 3300 Hz (at -30 dB) with a relatively flat frequency response between 600 and 3000 Hz. The central frequency is, in this case, equal to 1800Hz. It can be selected a 1500 Hz central frequency for Ham receivers.
The soft automatically decodes the speed (75, 150, 600, 1200, 2400 or 4800 bps) and the interleaver (short or long), in different character formats.
The radio-amateur frequency proposed for this mode is 14104 KHz (adjusted on the transceiver).
Important: in USA, 110A text transmission is forbidden. PSE, check if it is allowed in your country.
This mode is available for licencied copies, only (otherwise, the decoding is stopped after 5 minutes). However the 75 bps sub-mode in format 8N1 (RX/TX) is free.
See specifications further on.
2) RS ID, Call ID (Prop ID)
These identifiers are now permanently monitored in background, by default (the CPU load being weak). The management of these identifiers has been improved.
For Call ID and "Prop ID" ("Propagation ID"), it is proposed four frequencies bandwiths for transmission and monitoring.
3590, 7040, 10148, 14075 KHz (to adjust on the transceiver).
All the minimum AF band, i.e. from 200 Hz to 2500 Hz can be used. These frequencies can be favourably scaned ("Transceiver" button).
http://f6cte.free.fr/The_RS_ID_easy_with_Multipsk.doc
http://f6cte.free.fr/The_Call_ID_and_Prop_ID
_easy_with_Multipsk.doc
3) Improvements of
- the SdR mode and frequency management,
- the ARQ FAE mode (in ALE or ALE400),
- the JT65, GMDSS and SELCAL modes.
110A specifications:
Baud rate: 2400.
Modulation: 8PSK (not differential, the exact phase being determined through known data) with a central frequency of 1800 Hz
Reception mode: USB
Character set: different synchronous or asynchronous formats are proposed (5 ITA2, 7 bits ASCII or 8 bits (ASCII+ANSI))
Shape of pulse: raised cosine
Bandwidth: about 3 KHz (300 to 3300 Hz)
Demodulation: coherent
Synchronization: automatic using the known data
Convolution code: except in 4800 bps, yes. The constraint lenght is equal to 7 bits,
Interleaving: except in 4800 bps, yes. Two interleavings are proposed: short or long. However, it is expected the possibility not to use interleaving.
Pmean/Ppeak: about 0.76 (specific to Multipsk in TX) Lowest S/N (on Multipsk): + 4 dB in 75 bps mode (first decodings at +1.5 dB) and + 10 dB in 2400 bps (the signal to noise ratio must be, in general, very good, to be able to decode this mode, i.e "excellent" at 2400 bps and "good" at 75 bps).
Each frame contains a synchronization preamble phase where the sub-mode is defined, a data phase where the unknown data is transmitted (mixed with known data to follow the transmission characteristics) , an "End of Message" ("EOM") phase and a final flushing phase (to finish de-interleaving and de-convolution operations).
An adaptative equalization is required at this speed (2400 bauds).
