Another experimental VOA Radiogram for July 30-31

Hello friends,


Last weekend's experiment with the transmission of an html-formatted VOA News story resulted in many successful decodes, but also several failures. The failures were mainly due to the base64 compression of the transmitted file, which requires all of the received characters to be received correctly. On shortwave, as we know, perfection is often elusive.

This weekend, we will transmit another html-formatted VOA News story. This time we will use Flwrap, another Fldigi add-on program. See details and instructions here: http://voaradiogram.net/post/148147415237/experimenting-with-web-pages-via-shortwave .

Because Flwrap does not require the html to be compressed, if the checksum fails, you have a Plan B: Copy the text in the Fldigi from <html> through </html>, paste it to a text editor (like Notepad), save it as an .html file, and open it in a browser.

Here is the lineup for VOA Radiogram, program 174, 30-31 July 2016, all in MFSK32 centered on 1500 Hz:

 1:31  Program preview
 2:41  Great Red Spot may heat Jupiter's atmosphere*
 8:31  High-speed travel in near-vacuum tube*
12:44  Strange purple orb in Pacific Ocean**
18:43  Three images
26:08  Closing announcements*

Very interesting VOA Radiogram for July 23-24

From Kim Andrew Elliott:

Hello friends,

Italian Broadcasting Corporation, IBC, has new MFSK32 transmissions. See the information below.

I have not been able to do a character-by-character analysis of all the reports on last weekend's Battle of the 55-wpm Modes, but it generally appears to me that MFSKI16 was best, followed by Olivia-8-1000, with BPSK63F most prone to errors. (In defense of BPSK63F, however, it has the narrowest bandwidth, and thus will be the most welcome on the amateur bands.)

Roger in Germany reminded us that BPSK63F, because it involves phase shift keying, may not work as well in AM mode, because, with fading, the two sidebands can be out of phase. The frequency shift keying of MFSK and Olivia suffer less from this phenomenon. I decoded the three modes using SSB on various receivers, but it still seems that BPSK63F had the most errors. Several listeners and I also decoded BPSK63F in AM mode (and a good signal) with 100% success.

Meanwhile, the html VOA Radiogram transmission schedule was received perfectly in many parts of the world, even where the MFSK32 images were fuzzy. (See some examples.)

This weekend, VOA Radiogram will again transmit an html document. This time, instead of using the Flmsg blank form, we will use the Flmsg file transfer form. When the content is all received, the file transfer window will open. You can save the document and open it when convenient.  (The photo in the document will come to your PC via the Internet rather than shortwave.) (See instructions at http://voaradiogram.net/post/147385924137/this-weekend-again-web-pages-via-shortwave )

Here is the lineup for VOA Radiogram, program 173, 23-24 July 2016, all in MFSK32, all centered on 1500 Hz:


 1:32  Program preview
 2:52  New map of cerebral cortex*
 9:21  X-shaped configuration at center of Milky Way*
14:41  US Navy will visit New Zealand*
19:04  Amateur radio numbers decline in Germany*

Epic 55WPM showdown on VOA Radiogram for July 16-17

For the first time in a while, VOA Radiogram gets experimental, with three different 55 WPM modes. These are BP63F, MFSK16, and Olivia 8-1000. There will also be a message in Flmsg format, again for the first time in a while.  This might be a good show to record and try with different decoders.
--------

From Kim Andrew Elliott:

Hello friends,

Have your white laboratory coats ready, because VOA Radiogram will be very experimental this weekend.

Battle of the 55-wpm modes.  VOA Radiogram listener and contributor Mark Hirst in the UK suggests an experiment with the BPSK63F mode. His interest was generated by an article in the August QST magazine about the "flavors of PSK." It noted that BPSK63F, with its forward error correction,  has a "remarkable ability to be decoded under poor conditions."

During the early editions of VOA Radiogram, we did transmit BPSK63F a few times. This weekend, we'll do it again, in comparison with two other modes that also have speeds of about 55 words per minute: MFSK16 and Olivia 8-1000.  The RSID for each mode will be followed by a 15-second tuning signal, in case you must manually change modes. More details below in the lineup.

The return of Flmsg.  This weekend's program will include on item in Flmsg format. Flmsg is an add-on to Fldigi that allows the transmission and reception of message forms and formatted html documents.

If you don’t already have Fldigi, download it from https://sourceforge.net/projects/fldigi/files/fldigi/ . Download Flmsg  from https://sourceforge.net/projects/fldigi/files/flmsg/ .

To make Flmsg work with Fldigi, in Fldigi: Configure > Misc > NBEMS > under Reception of flmsg files, select Open with flmsg and Open in browser, and below that indicate where your Flmsg.exe file is located – probably somewhere in Program Files(x86).

If all goes well, when the digital mode transmission concludes, Flmsg will open a new window of your web browser to display a formatted VOA Radiogram transmission schedule. If your default browser is not open, Flmsg will open it for you. (If you are asked to ignore checksum error, select Yes.)

If it doesn’t work the first time, or you don’t have Flmsg installed, you can try this later from your recording.

In Windows, an easy way to save the received document is to use the Microsoft Snipping Tool. Please send that image as an attachment to your reception report.

If you are an Android user, TIVAR does not accommodate Flmsg files. But a similar app, AndFlmsg, as its name would indicate, does. Unlike TIVAR, which is receive-only, AndFlmsg encodes as well as decodes and is used by radio amateurs for message traffic. After the Flmsg is received, go to the index screen and press on the name of the file.

Here is the lineup for VOA Radiogram, program 172, 16-17 July 2016. All modes are centered on 1500 Hz.


 1:35 MFSK32: Program preview (now)
 3:06 MFSK32: Osmosis to generate electricity*
      Battle of the 55 wpm modes ...
11:33 BPSK63F: "Snowline" around new star

VOA Radiogram for July 9-10

From Kim Andrew Elliott:

Hello friends,

During the past two weekends, many listeners noted that the RSID for the Olivia modes did change the mode. In an attempt to fix that problem, I have amplified the RSID for this weekend’s Olivia 32-1000 by 2.5 dB.

Also, please make sure that Fldigi is configured to search the passband for the RSID. Such a search is necessary given that the MFSK32 is centered on 1500 Hz, but the Olivia is centered on 2000 Hz. In Fldigi: Configure > IDs > RsID: select Searches passband. In newer versions of Fldigi, you can alternatively left-click on the RxID in the upper right of the main screen, then select Passband.

We are experimenting with Olivia at 2000 Hz because text modes at these higher frequencies might be able to escape interference consisting of voice, music, and even some types of noise. Soon we will return to less nerve-wracking shows where all the modes are at the same audio frequency.

Last week, on the show, I erroneously introduced the Olivia 32-1000 and Olivia 32-2000. Apologies for the confusion.

Here is the lineup for VOA Radiogram, program 171, 9-10 July 2016, all in MFSK32 centered on 1500 Hz except where noted:

 1:36  Program preview
 2:51  Saturn's moon Titan might support life*
 7:47  New Horizons space probe extends its mission*
13:01  Lightning rod may have saved Maryland's State House*
18:42  Olivia 32-1000/2000 Hz: Pasta is good for you

It's Night of Nights time again!

Doesn't seem like a whole year, but it is.  The annual triumph of the human spirit known as the Maritime Radio Historical Society Night of Nights is Tuesday, July 12 (Pacific Time). Believe it or not, this is Night of Nights XVII!  That's a lot of dits and dahs in the ether.


Night of Nights

Why is this night different from all other nights?

On all other nights, we transmit Morse code from ham stations or KSM. On this night alone, KPH, the Power House, comes back to life.

The Night of Nights celebrates maritime commercial Morse telegraphy's refusal to die. The last US commercial Morse message was sent at 0000 UTC July 13, 1999, and that was supposed to be the end of that.  Most of the great US commercial stations quickly became condos and shopping malls.

KPH, former RCA San Francisco Radio, Pt. Reyes, was different.  Through superhuman effort and cooperation from the Point Reyes National Seashore, the former staff and friends re-opened this vast facility and got it back on the air.  It is said that the receiver filaments were still lit... the station manager had refused to let KPH die.

Getting a former RCA commercial station back on the air is something like restoring a classic car whose parts haven't been made in generations. In this case, though, major challenges include pole climbing, reviving control lines miles long, and caring for old buildings going back as far as the Marconi era.

They did it.  Borrowing the KPH call back from new licensee Globe Wireless (itself gone now), and getting a lot of help from true believers everywhere, the great station spoke again.   Now, it does so every year, along with other CW calls heard on this night alone.

These include WLO, and some US Coast Guard facilities in California. The Guard dropped Morse about the same number of years ago, and the stations have since been remoted to the new Commcom.  With all the equipment changes going on, every year may well be the last for USCG.


Details

All the poop, with the many frequencies to be used, is in the latest MRHS newsletter.   (He says Friday, but it's a Tuesday.)  Link follows.

From Richard Dillman:

Join us on he air or in person at the RCA receive site in Point Reyes, CA as we originate stations KPH, KFS and KSM from our transmit site in Bolinas.  WLO in Mobile, AL and USCG stations NMC, NMW and NMQ will be on the air as well.

All the details are in Newsletter No. 55, just published.  Also read details about the magnificent R3 diversity receiver and the enigmatic H over 2 antenna.  Get it all at:

VOA Radiogram for July 2-3

From Kim Andrew Elliott:

Hello friends,


Last weekend VOA Radiogram heard from many interesting places (e.g., Morocco, Poland, Russia,  Japan, Australia, Colombia), saw four YouTube videos (from Colorado, Germany, Maryland, and Japan), and heard and decoded the modes fighting off over-the-horizon (OTH) radar. See examples at http://voaradiogram.net. Just scroll down.  See examples also at https://twitter.com/voaradiogram 

Last week's MFSK32 performed well, and the Olivia 16-1000 even better. There were a few instances where the Olivia 16-1000 not not decode successfully. This week will will  try the slower (24 wpm) but more robust Olivia 32-1000.


At one point in the show I mistakenly refer to Olivia 32-2000 ...



VOA Radiogram now changes to Olivia 32-2000 centered on 2000 Hz


But Olivia 32-1000 is the only mode on the program other than MFSK32.  I apologize for the confusion.

Here is the lineup for VOA Radiogram, program 170, 2-3 July 2016, all in MFSK32 except where noted:


 1:20  Program preview 
 2:37  Bamboo as a building material*
 8:09  Juno spacecraft nears orbit around Jupiter*
15:12  Olivia 32-1000 at 2000 Hz: Neptune vortex* **
21:20  MFSK32: Image and closing announcements*

* with image


** and, yes, it is Olivia 32-1000, regardless of how Kim introduces it.

German weatherfax on 15988 kHz

Deutscher Wetterdienst, the German Weather Office in Hamburg, has at least temporarily resumed a FAX schedule from its Pinneberg transmitter on the assigned frequency of 15988.0 kHz (dial 15986.1 USB).  This frequency is not listed in the Utility Planet column that came out yesterday, because they have only been using it for a couple of days.

As of July 1, however, it's still there, so maybe now it's worth mentioning.  It has an S7 signal on the Netherlands WebSDR, and just started a new chart at 1834 UTC.
