Buzzer/ S28 is not buzzing

The notorious Russian "Buzzer," aka S28, is not transmitting its usual marker on 4625 kHz R3E/H3E.  It seems to have stopped after a voice message.  Now there is only circuit noise of a sort also heard on Russian Air Force voice frequencies.

Occasionally, there is maybe one secondof an odd noise that sounds a bit like mistuned ALE, but isn't.

The parallel frequency, 6998 kHz, is completely silent.

I know it's Field Day, but here's VOA Radiogram for June 25-26

From Kim Andrew Elliott:

Hello friends,

VOA Radiogram this weekend will include the Olivia 16-1000 mode with a center frequency of 2000 Hz. If you happen to experience co-channel interference consisting of voice and/or music, the robustness of the Olivia 16-1000 mode in combination with the higher audio frequency might allow a successful decode. At 40 words per minute, Olivia 16-1000 is faster than Olivia 64-2000.

Here is the lineup for VOA Radiogram, program 169, 25-26 June 2016, all in MFSK32 except where noted:

 1:35  Program preview
 2:45  Pluto may have liquid ocean*
10:17  Fiery re-entry for junk from ISS*
16:33  Olivia 16-1000 (2000 Hz): Zuckerberg PC security*
22:06  MFSK32: Image, mobile app transmitted by shortwave*
26:04  Closing announcements*

* with image

Please send reception reports to radiogram@voanews.com

VOA Radiogram transmission schedule
(all days and times UTC):
Sat 0930-1000 5745 kHz
Sat 1600-1630 17580 kHz
Sun 0230-0300 5745 kHz
Sun 1930-2000 15670 kHz
All via the Edward R. Murrow transmitting station in North Carolina.

The Mighty KBC will transmit to North America Sunday at 0000-0100 UTC (8-9 pm EDT) on 9925 kHz, via Germany. A minute of MFSK32 will be at about 0030 UTC. KBC will also broadcast to Europe Sunday at 0900-1000 UTC on 6095 kHz. A minute of MFSK32 will be at about 0930 UTC. Reports for KBC reception and decode to Eric: themightykbc@gmail.com .

DigiDX will provide DX and media news in MFSK32 and a mixture of other modes:
Sunday 2130-2000 UTC, 15770 kHz, via WRMI Florida
Sunday 2330-2400 UTC, 11580 kHz, via WRMI Florida
Monday 2000-2130 UTC, 6070 kHz, via Channel 292 Germany
Look for any additions or changes to the DigiDX schedule at http://www.digidx.uk/ or https://www.facebook.com/digidx/

IBC (Italian Broadcasting Corporation) has a broadcast to Europe on 6070 kHz, Wednesdays, 2000-2200 UTC, with MFSK32 and Olivia 16-500 at 2030-2100 UTC. See http://ibcradio.webs.com/ for the complete schedule and contact information.

Download apps via shortwave? A recent transmission of a mobile app from shortwave station KTWR in Guam, to a DRM receiver in Thailand, has caused much discussion. See coverage at drmna.info and The SWLing Post. While DRM offers more bandwidth and faster download speeds than the VOA Radiogram method of digital modes via analog radio, VOA Radiogram data can be received on any radio.

Software to decode VOA Radiogram includes Fldigi from w1hkj.com and, for Android devices, TIVAR.

Thank you for your reports from last weekend. Reception conditions were generally good, so the Olivia 64-2000 did not get much of a workout. Decodes were good even in Perth, Western Australia.

A reminder that Fldigi saves decoded MFSK images as .png files in the folder \fldigi.files\images\.  If convenient, please attach those .png files to your reception reports.

I hope you can tune in and write in this weekend.

VOA Radiogram, 18-19 June

From Kim Andrew Elliott:

Hello friends,

VOA Radiogram received some great publicity in the July issue of QST magazine. If you don't receive the magazine, you can see images of the article here. They did change my name to "Kim Andrew Ellis," but that's OK: I don't need the publicity, but the concept of using digital modes on analog shortwave radio to provide information to places where the Internet is restricted or not available does need the publicity. [Hence these weekly postings. -Hugh]

Apologies to those tuned last weekend to the Sunday 1930-2000 transmission on 15670 kHz. It abruptly left the air at about 1949 UTC. There were problems with the transmitters at the North Carolina site, which is to be expected occasionally given that the transmitters are 50 to 60 years old.

Another challenge last weekend was strong interference, perhaps an over-the-horizon (OTH) radar, during the Saturday 0930-1000 UTC transmission on 5745 kHz. It was especially loud in Alaska, per this video made by Paul in Alaska. [Definitely an OTH radar. It obliterated this transmission here in CA a couple of weeks back. Likely candidates are Russian 29B6 and UK Pluto. -Hugh] (I was not able to decode the MFSK32 from the video, but maybe you will have better luck.)  The interference was also heard by Mike in Washington state. If the noise returns this weekend, we'll be prepared: the show includes a story in Olivia 64-2000.

Here is the lineup for VOA Radiogram, program 168, 18-19 June 2016, all in MFSK32 except where noted:

 1:33  Program preview
 2:38  Birds' brains more complex than imagined*
 8:35  Large planet orbits binary stars*
17:40  Olivia 64-2000: North Dakotans overturn farm law*
24:19  MFSK32: Image and closing announcements*

VOA Radiogram for June 4-5

From Kim Andrew Elliott:





Hello friends,


I'm back to a (somewhat) normal schedule now after my family's visit to Vancouver and Alaska. I did not have many opportunities to tune in to VOA Radiogram, but I did receive the broadcast May 22 at 0230 UTC on 5745 kHz, in the Pacific off British Columbia. I did not get to the balcony of our stateroom until the Olivia 16-500, which decoded 100% using a Sangean ATS909X acoustically coupled to a tablet running TIVAR.


I have not yet had a chance to analyze all the reports on the Olivia 64-2000, 32-1000, and 16-500 comparison during program 164, but the preliminary verdict is: they're all good.



This weekend, VOA Radiogram will be all MFSK32. It will include an item in Russian. You will need the UTF-8 character set to decode the Cyrillic text. In Fldigi: Configure > Colors & Fonts > set Rx/Tx Character set to UTF-8.


Here is the lineup for VOA Radiogram, program 166, 4-5 June 2016, all in MFSK32:



 1:34  Program preview
 2:55  50 Cent Party supports China on Internet*
 8:26  US Embassy in Beijing takes break from social media*
14:18  RFE/RL will end shortwave transmissions in Russian* **
21:44  Train trip in Alaska*
26:04  Closing announcements*

Next Two VOA Radiogram Shows (May 21-22, 28-29)

From Kim Andrew Elliott:

Hello friends,

I have prepared the next two editions of VOA Radiogram in advance, so they will not include any up-to-date news items. They will, however, be interesting shows …

Program 164, 21-22 May 2016 will begin with an MFSK32 introduction, then transmit the same VOA Science World item about boiling water on Mars in Olivia 64-2000, Olivia 32-1000, and Olivia 16-800.  This will be a chance to compare the performance of these three modes, which all have speeds in the 20-30 wpm range. The program will conclude in MFSK32 with an image and closing announcements.  

Program 165, 28-29 May 2016 will consist of six science images from the VOA Science World Blog. All of these will be in MFSK32, although the sixth, showing a Falcon 9 rocket launch, will be transmitted in both MFSK32 and MFSK64. Images in MFSK32 and MFSK64 require the same amount of time to transmit; the MFSK64 image has more resolution but is more susceptible to interference. After the MFSK64 image, VOA Radiogram will return to MFSK32 for closing announcements.

Please send reception reports to radiogram@voanews.com .

VOA Radiogram transmission schedule
(all days and times UTC):

Sat 0930-1000 5745 kHz
Sat 1600-1630 17580 kHz
Sun 0230-0300 5745 kHz
Sun 1930-2000 15670 kHz
 
All via the Edward R. Murrow transmitting station in North Carolina.

The Mighty KBC schedule has been changing in recent weeks. Try Sunday at 0000 UTC (Saturday 8 pm EDT) on 9925 kHz (via Germany), with the broadcast continuing until 0200 or 0300. The minute of MFSK32 may be at about 0130 or 0220 UTC. Consult http://kbcradio.eu or http://facebook.com/themightykbc for updates on the schedule. Reports for KBC reception and decodes to Eric: themightykbc@gmail.com   

DigiDX will transmit DX news in MFSK32 and perhaps other modes on its usual schedule:
Sunday 2130-2200 UTC - 15770kHz via WRMI Florida
Sunday 2330-2400 UTC - 11580kHz via WRMI Florida
Monday 2000-2030 UTC - 6070kHz via Channel 292 Germany
Consult https://www.facebook.com/digidx/ for any additions or changes to this schedule.

Thank you for your reports from the weekend of 14-15 May. Reception conditions were generally good, and I saw some excellent decoded images. You can see some examples at https://twitter.com/voaradiogram .

Please tune in and write in during the next two weekends.

It's not you, the AFD does seem a bit quiet.....

Apparently a lot of schedules aren't happening.  I gave up in disgust an hour ago, though someone has since heard a brief 170-shift RTTY transmission on one of the 40 meter frequencies.

Expanded Armed Forces Day Communication Test begins tomorrow (May 14)

As has been the case for a number of years now, the military-amateur crossband comm tests and observances are done the week before Armed Forces Day. This is to avoid conflict with the Dayton Hamvention. This year it starts tomorrow morning, US time, and some parts of it run until around 0400 Zulu on the 5th.

The AFD comm test is divided into several different activities. These are:

1. Military-Amateur Crossband Communications

In this activity, MARS and military units using their authorized frequencies outside amateur bands work amateurs who remain in-band.  This used to be tricky with some ham gear, which didn't receive far enough out of band.  Today, it's a lot easier.

Also, some of the frequencies used in the 60 meter band are authorized to amateurs, so comms will be simplex on-frequency.

The number of participating stations, times (all Zulu), and frequencies has grown too big to put in a blog entry. It's best just to link to the schedule published by Army MARS.

Again this year, amateurs will be able to link via ALE. The full implementation of this mode, with scanning, is tricky with ham gear. Rapid band switching requires very good autotuning.

In the past, not all stations have been on-air for the entire time intervals shown in the schedule.
 

2. Secy. of Defense Message Test, using digital modes

This one sounds pretty interesting for utility types. A message from the Secretary of Defense is sent in a number of modes used by the military, and also several modes used by hams.

The "military serial PSK" referred to is usually known as "110A" in utility logs. It's the same stuff. As they say, it's not the easiest mode for good copy with amateur-grade equipment and Windows computers, though I've had very good luck with Windows 7 and the stronger signals. Here's a better link to the MS-DMT software mentioned in the schedule. MultiPSK works too.

The scary sounding "wide FSK" is just standard military RATT, 75/850, low mark.  It's always fun to hear this mode unencrypted and actually be able to print something.

Here's the schedule:

To practice receiving signals in this mode [110A], tune to the following dial frequencies at 1201Z, 1801Z or 0001Z daily.

VOA Radiogram for May 14-15

From Kim Andrew Elliott:

Hello friends,

You might remember that last year, the BBG, parent agency of VOA, issued a Request for Proposals for the development of a decoder app for VOA Radiogram. There were no proposals, but that might be because of the short deadline. It's possible that the RFQ will be issued again, but only if there is potential interest by developers. So let me know if you are an interested developer.

The specifications in the RFQ would be the same as in the 2015 RFQ, which you can see here ...

http://www.bbg.gov/wp-content/media/2015/09/RFQ-BBG50-Q-15-0915MD-Software-Development.pdf

VOA Radiogram this weekend will be all MFSK32, except for the transmission schedule in Olivia 64-2000 under the closing music. The show will include six MFSK images.

Here is the lineup for VOA Radiogram, program 163, 14-15 May 2016, all in MFSK32 except where noted:

 1:34  Program preview

 2:46  Giant Magellan Telescope in Chile*
 8:42  UK government review of the BBC*
14:29  RFE/RL Crimea website blocked*
18:35  Radio/TV Martí now receiving letters direct from Cuba*
23:11  Image from South Pole Journal*
26:36  Closing announcements*
28:15  Olivia 64-2000: Transmission schedule under music

*  with image

Please send reception reports to radiogram@voanews.com.

VOA Radiogram transmission schedule

DVA Update

New ALE calls and frequencies are still being discovered for the US Department of Veterans Affairs (DVA) emergency radio system.  Several lists are being circulated, and there seems to be a certain variation between regions of the country.

At this QTH in Southern California, the following frequencies have been heard active:

2025.6   2726.0   3355.1   3393.6   5038.5   6335.6*   6981.1   7480.0   10389.6   14441.6   15628.6   17492.6   20200.1   22738.0*   22921.6

The * means the frequency is used by Rockwell Collins in its new ARINC UrgentLink system.  DVA IDs are rare on these, but too many people have heard them for it to be bad data.


 The following ALE identifiers have been copied here:

1536   1616   2002   3031   3033   5090   5190   5286   5287   5290   5311   5312   5313   5400   5420   5520   5810   5826   5895   5897   5898   5899   5950   6030   6051   6052   6053   6191   6203   6260   6400   6491   6541   6542   6543   6581   6591   6601   6602   6603   6620   6630   6640   6714   6741   6743   6780   6790   7570   8356   13536  598001

Note the emergence of several consecutive number sequences. The meaning of these, if there even is any, is not known.  The absence of any IDs beginning with the number "4" is due to sheer chance.  These have been copied in other places.


VOA Radiogram for May 7-8

From Kim Andrew Elliott:

Hello friends,


Lately we have been trying to determine why some listeners have less success with Olivia 64-2000 than with MFSK32, even though, in theory, Olivia 64-2000 should be more robust. I suggested that the problem might be related to the bandwidth of the receiver, given that Olivia 64-2000 is 2000 Hz wide.


Christopher, K6FIB, a key adviser to VOA Radiogram, thinks the performance of Olivia is related to the processing power of the PC or the mobile device. Paul in Europe provided evidence of this in his TIVAR Android shoot-out. Other listeners wonder if it could be other components, such as the microphones on Android devices, which would be important if acoustic coupling from the radio to the device is used.


VOA Radiogram this weekend will include an eight-minute story in Olivia 64-2000. This will allow further experimentation. If we enjoy poor reception conditions, the experiments will be even more interesting.


Here is the lineup for VOA Radiogram, program 162, 7-8 May 2016, all in MFSK32 except where noted:



 1:34  Program preview
 2:41  Rubbish-burning experiment in Norway*
 7:55  Olivia 64-2000: UAE may make mountain to change climate*
18:34  MFSK32: FCC considers change to amateur data regulations*
23:37  Closing announcements*

VOA Radiogram for April 30 - May 1

From Kim Andrew Elliott:

Hello friends,

This weekend's VOA Radiogram will include a news item in Olivia 64-2000. This might be an opportunity to investigate why some listeners do not have successful decodes of this mode. One way to do this is to use two radios, with two different bandwidths. The hypothesis is that a wider bandwidth should work better with the wide Olivia 64-2000 mode. You could decode "live" from one radio while recording  from the other radio for later decoding.

Here is the lineup for VOA Radiogram, program 161, 30 April-1 May 2016, all in MFSK32 except where noted:

 1:33  Program preview
 2:43  Russia launches rocket from new cosmodrome*
 6:44  Freedom House press freedom report*
14:01  Olivia 64-2000: Dwarf planet has a moon*
23:31  MFSK32: Old RFE/RL transmitting site in Spain*
26:07  Closing announcements*

Hopefully no RHC co-channel with VOA Radiogram for April 23-24

From Kim Andrew Elliott:

Hello friends,

Last weekend, Radio Habana Cuba had a special transmission on 17580 kHz, creating an interesting co-channel situation with VOA Radiogram Saturday at 1600-1630. RHC caused only minor interference in Europe, but in parts of the Americas, decoding VOA Radiogram was difficult. In this video by Tim in Colorado, VOA Radiogram and RHC are fairly evenly matched …   


[Here neither one was particularly audible, but RHC wins on points.  That distinctive voice they use faded in and out more times than the VOA's digital tones, which stayed pretty much out.  -Hugh]

 Last weekend’s Olivia 64-2000 provided some good decodes despite poor reception conditions.  Here is an example from a receiver in Sydney, NSW, Australia …


On the other hand, some listeners were not as successful with Olivia 64-2000, and found that this mode did not perform as well as MFSK32 – which is much faster. I wonder if the problem is related to the receiver’s bandwidth. Olivia 64-2000 extends to 2500 Hz above and below the carrier. If any of that data is “clipped,” the decode might be less than 100%. We could try some experiments with this in future programs.

This weekend, all the content will be in MFSK32, except for the transmission schedule in Olivia 64-2000 mixed with the closing music.

Here is the lineup for VOA Radiogram, program 160, 23-24 April 2016, all in MFSK32 except where noted:

 1:34  Program preview

Is ANPOPS in Southern California?

It's long been assumed that the Rockwell Collins "ARINC UrgentLink" station using the 2G ALE address of ANPOPS is at or near the old ARINC headquarters in Annapolis, MD.  Perhaps it was at one time.

Lately, however, hundreds of ALE decodes have given a clear indication that it is most likely coming from somewhere in Southern California.

Let's look at some statistics. Here are the average S/N (as shown on PC-ALE) and the average frequency for the only stations audible at this QTH in SoCal:

Stn           S/N       Fq
010MDR    8.7    11206.2
103SCC    6.3    11300.3
104LKW    6.7    10559.3
105LAN     6.8     6792.7
ANPOPS    9.0    6163.0

As noted above, the sample on these is rather large.  It's over 50 normal sized pages of PC-ALE orderwire loggings. It includes a couple of all-night runs, to somewhat lessen the effect of diurnal band changes.  As far as I know, all of these stations are using very similar 125-watt radios with simple vertical antennas.

Note that ANPOPS actually averages a higher signal to noise ratio than the four other stations, all of which are known to be in the direct RF field at my location.  The only station whose average comes even close is 010MDR, Marina Del Rey, which is verified as coming from a business park only a few miles away from here.

ANPOPS also tends to be heard on lower frequencies.

Neither condition would support an origin in Maryland.  This result is simply not consistent with the known characteristics of recent transcontinental propagation. Band conditions have not been especially good, and genuine F2 skip from the eastern US has been weaker than normal.

And so we have something of a mystery, but then this system has been known for those.
