Double Duty VOA Radiogram for April 19-20

From Kim Andrew Elliott:

Hello friends,

Last weekend's experiment with the "mystery mode," MFSK8 as it turned out, was mostly successful. I reduced the level of the MFSK8 to 8 dB below the level of the MFSK32, because unattenuated MFSK8 at a piercing audio frequency of 2300 Hz can be rather painful to listen to.

This weekend, we'll repeat the contact information and schedule in MFSK8, but we'll move it to 1000 Hz, which is easier on the ear. With MFSK32 and MFSK8 both at full level, a distorted, other-worldly sound resulted. So I reduced the MFSK8 to 4 dB under the MFSK32. You can still hear what sounds like distortion, but it should be harmless. Probably. I hope.

If you prefer an easy, set-it-and-forget-it decoding experience, just do the MFSK32 at 1500 Hz. If you want more of a challenge, then run two instances of Fldigi, or Fldigi and another decoder such as MultiPSK, or record the program, to see the MFSK8 output. Please remember that MFSK8 must be precisely tuned (it will likely be received a few Hz above or below 1000 Hz) for a successful decode.

Please let me know if you think the simultaneous modes are making the MFSK32 images "noisier."

Here is the lineup for VOA Radiogram, program 55, 19-20 April 2014 (content in MFSK32 centered on 1500 Hz):

01:39  Program preview
02:57  Survey of US software developers, with image

Solar Peak VHF DX Log Part 8 (Supplemental from 4/10)

All intercepts made in Southern California by the author, using a WiNRADiO G33DDC SDR and a PAR EF-SWL end fed 45' wire. All frequencies kHz, all times UTC.

OM = male, YL = woman, SS = Spanish, EE=English, Disp=Dispatcher, Unid = Unidentified.

Tones are CTCSS (Continuous Tone Coded Squelch System) aka "PL."
CSQ = no tone in use (Carrier SQuelch)

Frequency ... Callsign ... Mode ... Description ... Time ... Tone

30740.0    Unid    FM    SS/EE/OM disp, constant phone ring and another OM bg, some beeps. Like most of these, the speaker goes back and forth between Spanish and accented English. Usual fast talking.    2027    107.2

30800.0    Unid    FM    EE/SS/OM disp, mostly EE but some SS. Usual fast talking.    2009    88.5

31060.0    Unid    FM    SS/OM disp, loud, YL, OM, & phone bg. "Coffee shop." Everything else in SS. Talking even faster than usual.    2012    91.5

31080.0    WPYJ841    FM    Hampden & Worcester County, MA, YL identifying as "Base 3." Followed open-squelch noise like rptr or remote. Likely rptr in use. Working mobiles in a large wide-area radio system used for transportation support. Mobiles calling it "Channel 3." The other weird things on this freq are probably skip getting in through the input.    2220    100.0

Interesting Participatory VOA Radiogram for April 12-13

If you couldn't hear the first VOA sked last weekend, on 5745 at 0930 UTC, it wasn't your equipment. Due to scheduling mixups, it was never broadcast.

From Kim Andrew Elliott:

Hello friends,

After last weekend's schedule mishap, the VOA Radiogram transmissions should be back to their regular times and frequencies this weekend:

UTC Day
UTC Time
Frequency

Saturday
0930-1000
5745 kHz

15670 kHz


All transmissions via North Carolina

Mystery mode: VOA Radiogram, for the weekend of 12-13 April 2014, will be all MFSK32 centered on 1500 Hz, but there will also be a mystery mode transmitted simultaneously at an audio frequency of 2300 Hz. (The RSID will help unlock the mystery of the mystery mode.)

You can decode both the MFSK32 and the other mode by 1) running two instances of Fldigi, 2) running Fldigi and another decoding software such as MultiPSK or DM780, or 3) recording the show and decoding the mystery mode later.

The audio frequency of the mystery mode needs to be tuned very precisely. It will probably be a few Hz above or below 2300 Hz. The content is the VOA Radiogram email address, website URL, and schedule, transmitted over and over, so you will have plenty of time to achieve a successful decode.

One of the MFSK32 VOA news items will be in Spanish. You will need the UTF-8 characters for the accented letters to display correctly. Find the UTF-8 setting via  Configure > Colors and Fonts. 

Here is the lineup for VOA Radiogram, program 54, 12-13 April 2014 (all MFSK32 centered on 1500 Hz except where indicated):

 1:43  Program preview
 2:58  Mystery mode starts centered on 2300 Hz
 4:44  Survey of trust in the Internet, with image
13:00  Intel's use of non-conflict minerals, with image
19:15  US Navy developing fuel from seawater, with image
24:19  VOA Spanish on "cardio," with VOA Voz de América logo
27:10  Closing announcements

Please send reception reports to radiogram@voanews.com

Thanks for your reports to VOA Radiogram from the past weekend. I will begin to answer them today. I look forward to hearing from you this weekend.

Set and Forget VOA Radiogram for April 5-6

From Kim Andrew Elliott:

Hello friends,

Last weekend's "battle of the 100-word-per-minute modes" produced useful results. Based on a quick analysis of the percentage of correct characters, the average of all responses is…

MFSK32                98%
MT63-1000L        90%
Thor25x4             86%
PSKR125               74%

[My results were very close to these percentages. Around 100% for MFSK32, 99-100% for MT63, mediocre copy on the Thor, and rough copy on the PSKR125. PSK modes don't seem to fare well in this particular application. -Hugh]
 
The MT63-1000L would have had an even better result if it had not been for four occasions of no decode at all. In situations where any MT63-1000L text was received, its performance was very close to that of MFSK32.

MFSK32 does have the advantage of being about 20 words per minute faster than MT63-1000L. Furthermore, MFSK32, unlike MT63-1000L, can be used for images.

This weekend, VOA Radiogram will return to an all-MFSK32 "set it and forget it" format. I do this at the risk of losing the interest of those of you who prefer a program replete with experiments. The program will be interesting in that it will include four images and an Flmsg CSV form with the updated VOA English transmission schedule.   

Here is the lineup for VOA Radiogram, program 53, 5-6 March 2014:

All MFSK32 centered on 1500 Hz...

1:36  Program preview
2:40  Head of Russian social network resigns, with image
9:28  NASA aircraft research, with image
16:13  Maryland company helps in search for MH370, with image
23:04  VOA English broadcast schedule as Flmsg* CSV form
26:44  Closing announcements

*To make Flmsg work with Fldigi (both can be downloaded from w1hkj.com), in Fldigi: Configure > Misc > NBEMS -- Under Reception of flmsg files, check both boxes, and under that indicate where your Flmsg.exe file is located.

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 17860 kHz
Sun 0230-0300 5745 kHz
Sun 1930-2000 15670 kHz
All via the Edward R. Murrow transmitting station in North Carolina.

Reception of the Sunday 0230 UTC broadcast in Europe: This broadcast is audible in Europe but occurs at a rather inconvenient time for Europeans. If you are in Europe, please consider unattended reception of this transmission. Three ways to do this involve leaving you radio on and tuned to 5745 kHz all night: 1) Use the Audacity audio recording software, specifically its Transport > Timer Record feature. 2) Use Fldigi's File > Text Capture feature, then retrieve the decoded text from the file that will contain mostly gibberish. 3) Instead of using Fldigi text capture, scroll up through the receive pane to find the decoded text, which you can copy and paste to a text editor or word processor.

The Mighty KBC will again transmit a minute of MFSK64 Saturday at about 1230 UTC on 6095 kHz, and Sunday at about 0130 UTC (Saturday 9:30 pm EDT) on 7375 kHz. Both frequencies are via Germany. STF Radio International is also planning tests on The Mighty KBC, presumably again in MFSK32 about 15 minutes after my MFSK64 transmissions.

Amateur radio digital nets: As KD9XB, I usually check in to the New York NBEMS net Saturdays at 1400 UTC (10 am EDT) on 7036 kHz and the Pennsylvania NBEMS net Sundays at 1500 UTC (11 am EDT) on 7072.5 kHz. I occasionally also check in to the USeast NBEMS net Wednesdays at 2300 UTC (7 pm EDT) on 7036 kHz. All these nets are USB and start with Olivia 8-500, then change to another mode such as MFSK32 or MT63-1000L for messages.

Thanks for your reception reports last weekend, and I look forward to hearing from this weekend.

ONEMI May Have Changed Frequencies

The frequencies in my last list used to work just fine here, but now several seem to be either off by 500 Hz, or the wrong sideband, or something.

Still checking.

Chilean Earthquake Emergency on HF

I've been hearing some ALE soundings from OMEMI, Chile's emergency management agency.

The thing to understand about Chile is that it's very long and skinny on a N-S axis, so its coastline is very, very long and evacuating the whole thing is a massive undertaking.  They've done it twice in two days.

ONEMI stands (in Spanish for) Oficina National de Emergencia del Ministerio de Interior (Ministry of Interior National Emergency Office).   It's USB ALE frequencies are:

    6834.0     6843.0     6861.0     6871.0     6877.0     9084.0     9087.0
    9091.0     9140.0     9150.0     10128.0     10135.0     10160.0
    10176.5     10187.0     10193.0     10218.0     10222.0     10234.0
    10244.0     17411.0     17426.0     17446.0     17450.0     17454.0

The navy uses LSB and USB on:
    6848.0     11429.0     17466.0     20400.0

Voice comms have been heard in the past after the autolinking.

Speed Test on VOA Radiogram for March 29-30

From Kim Andrew Elliott:

Hello friends,

This weekend, 29-30 March 2014, will be program 52 of VOA Radiogram. This means that VOA Radiogram has survived one year of shortwave broadcasting.

VOA Radiogram has been successful because of its audience: tuning in, decoding, experimenting, and sending in reports.

We will mark one year of VOA Radiogram with a "battle of the 100-word-per-minute modes." The same VOA News story will be transmitted using four modes that have a speed of more-or-less 100 words per minute.

Here is the lineup for VOA Radiogram, program 52, 29-30 March 2014:

1:51  MFSK32: Program preview
3:28  PSKR125 (110 wpm): VOA News re Ethiopia
7:42  MT63-1000L (100 wpm): Same VOA New story
12:34  Thor25x4 (100 wpm): Same VOA News story
17:58  MFSK32 (120 wpm): Same VOA News story, with image
23:55  MFSK32: US international broadcasting FY2015 budget
25:58  MFSK32: Closing announcements, with image

Each mode will be preceded by 5 seconds of silence, followed by the RSID, 5 more seconds of silence, and the RSID again.

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 17860 kHz
Sun 0230-0300 5745 kHz
Sun 1930-2000 15670 kHz
All via the Edward R. Murrow transmitting station in North Carolina.
(Many shortwave broadcast frequencies will change on 30 March with the beginning of the A14 season, but the VOA Radiogram frequencies stay the same, for the time being.)

The Mighty KBC, via Germany, will again transmit a minute of MFSK64 Saturday at about 1230 UTC on 6095 kHz and Sunday at about 0130 UTC on 7375 kHz. (KBC's change from 7375 to 9925 planned for this weekend has been postponed until May.) STF Radio International will also have a minute of digital modes during the same hour (simultaneous MFSK32 streams at 1500 and 2100 Hz).

Amateur radio digital nets: As KD9XB, I usually check in to the New York NBEMS net Saturdays at 1400 UTC (10 am EDT) on 7036 kHz and the Pennsylvania NBEMS net Sundays at 1500 UTC (11 am EDT) on 7072.5 kHz. I occasionally also check in to the USeast NBEMS net Wednesdays at 2300 UTC (7 pm EDT) on 7036 kHz. All these nets are USB and start with Olivia 8-500, then change to another mode such as MFSK32 or MT63-1000L for messages.

Each is USB, starting with Olivia 8-500 centered on 1500 Hz, then changing to MFSK32 or other mode for messages.

I have just about finished responding to VOA Radiogram reception reports from the weekend of 8-9 March, and will now start on reports from 15-16 March (program 50). Eventually, I will catch up!

I hope to hear from you this weekend.

Intresting Participatory Experimental VOA Radiogram for March 8-9

From Kim Andrew Elliott:

Hello friends,

On VOA Radiogram, program 49, 8-9 March 2014, the experiment will involve the audio frequency of a received MFSK32 transmission.

We hope that simple, receive-only applications (apps) are developed to decode MFSK32 on PCs and mobile devices. One requirement of MFSK is that the receiver and software be tuned to the precise frequency.

VOA Radiogram is typically transmitted on an audio frequency of 1500 Hz. The audio frequency as received tends to be a few Hz above or below 1500 Hz.

Would an MFSK32 app require an RxID to ensure that the received audio frequency is exactly correct? Or is there enough tolerance in MFSK32 that an RxID is not necessary?

VOA Radiogram, program 49, will begin with MFSK32 on a center audio frequency of 1600 Hz, with an RSID.

Just before 4:51 into the program, I will ask VOA Radiogram listeners to turn the RxID off and manually tune to an audio frequency of 1500 Hz.

Please let us know if you are able to decode the subsequent VOA News story without the assistance of the RxID.

During that VOA News story, you can turn the RxID back on.

For unattended reception, turn RxID off and set the audio frequency to 1500 Hz. You should decode everything after 4:51 into the show.

Here is the lineup for VOA Radiogram, program 49, 8-9 March 2014, all in MFSK32:

   1:37  1600 Hz: Program preview
 3:14  1600 Hz: Introduction to MFSK32 experiment
 4:51  1500 Hz: Cyber attacks on mobile devices, with image
10:33  1500 Hz: Ukraine telecommunications under attack
17:44  1500 Hz: Request for comments about shortwave, with image
20:11  1500 Hz: BBG FY 2015 budget request, with Flmsg* table
27:00  1500 Hz: Closing announcements

*Use Flmsg with Fldigi, both available from w1hkj.com.

Please send reception reports to radiogram@voanews.com

Winter SWL Fest

See you at the Winter SWL Fest, 14-15 March 2014, near Philadelphia. I'll be there to demonstrate to decoding of text and images on VOA Radiogram. Attend one or both days. Registration at the door is welcome. Information at swlfest.com.

The Mighty KBC

The Mighty KBC, with studios in the Netherlands and transmitters in Germany, will transmit a minute of MFSK64 Saturday at about 1230 UTC on 6095 kHz, and Sunday at about 0130 UTC (8:30 pm EST) on 7475 kHz. Eric enjoys receiving reception reports at themightykbc@gamail.com

The Saturday 0930 UTC broadcast

Now that this broadcast has been heard and successfully decoded in New Zealand, I will keep the 5745 kHz frequency for a few more weeks. Please ask your friends in the Asia Pacific region to try to receive the broadcast. Reception is also good all the way to the North America west coast. Try unattended reception while you sleep.

Daylight Savings Time in North America

On Sunday, 9 March, we in North America will move our clocks ahead one hour for "daylight savings time." For VOA Radiogram, this means that the broadcast Sunday at 1930-2000 UTC, on 15670 kHz, will now be at 3:30 pm EDT, 2:30 pm CDT, 1:30 pm MDT, and 12:30 pm PDT.

Personally, I would prefer that North America remain on "standard" time throughout the year. With year-round "standard" time, darkness, and a corresponding reduction in temperatures from the highs we have been experiencing in recent summers, would occur one hour earlier.   


Last weekend's Olivia experiment.


It was an interesting experiment. Olivia 64-2000 worked just about everywhere, including Japan. Olivia 32-2000 was almost as good. There were a few more errors with Olivia 16-2000, and several errors with the faster but less robust Olivia 8-1000.


I will begin responding to your reports Friday.
