Non-quantum-entangled VOA Radiogram for August 20-21

From Kim Andrew Elliott:

Hello friends,

YouTube videos showing the decoding of the WRMI digital special are now available via http://voaradiogram.net/post/149173780217/youtube-videos-of-the-wrmi-digital-special . If one or more of the videos is blocked in your country, it's because the music we used as an example of annoying co-channel interference may have run into rights issues.

This weekend on VOA Radiogram, most of the show will be straightforward, all in MFSK32. There is one twist in the form of an Flmsg item at the very end of the program that should result in an audio surprise. 

Here, again, is the information about Flmsg: Download it 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). (Mac users, this page might help: http://kf3g25cw.altervista.org/Links/Fldigi_Flmsg/Fldigi_Flmsg.MainPage.html )


Here is the lineup for VOA Radiogram, program 177, 20-21 August 2016, all in MFSK32 centered on 1500 Hz:


 1:31  Program preview (now)
 2:42  China launches hack-proof satellite*
 8:32  Twitter closes terror-linked accounts*
13:59  Why is Washington's subway system falling apart?*

KPH call sign returns to Pt. Reyes!

The Maritime Radio Historical Society, which maintains the historic Pt. Reyes maritime coastal radio site in cooperation with the US National Park Service, has made an agreement with the owners of the KPH and KFS calls. The MRHS transmitters will soon be using their original "KPH" call, whose mighty dahdidah didahdahdit didididit once ruled the Pacific.

According to Richard Dillman, the transmitters will be shifted back to their originally licensed KPH frequencies. When it's all done, a Night of Nights level activity will welcome them back to the Pacific airwaves.

The KSM call, which is a valid FCC commercial telegraphy license held by MRHS, will be retained in case the KPH authorization goes away in the future.

From MRHS:

Marine station KPH began life in 1905 in the Palace Hotel in San Francisco (thus the original PH call sign).  The station was destroyed in the 1906 earthquake and fire and was rebuilt at Green Street in The City.  It soon moved to Hillcrest above Daly City (south of San Francisco), then to the existing Marconi site in Marshall, Marin County, north of San Francisco in 1920.  Closed for the duration of WWII, KPH re-opened in 1946 at the point-to-point receive site at Point Reyes, CA with transmitters at the original 1914 Bolinas site.

We felt ourselves very lucky indeed to be able to fly the banner of maritime communications high with coast station KSM.  But we mourned the loss of the romance, resonance and rhythm of KPH.  Several efforts were made over the years to recover the famous call sign but none bore fruit... until now.

KPH provided continuous service from the Bolinas/Point Reyes sites until 30 June 1997 when operations ceased.  The license had been sold to Globe Wireless and with it went one of the most famous of all coast station call signs - KPH.

The MRHS began its restoration program in 1999.  It was soon decided that to do justice to the facilities now under our stewardship we would need our own commercial coast station license.  We applied for such a license which was granted with the call sign KSM, ironically the call once assigned to a historic Globe Wireless station in Southern California. 

We felt ourselves very lucky indeed to be able to fly the banner of maritime communications high with coast station KSM.  But we mourned the loss of the romance, resonance and rhythm of KPH.  Several efforts were made over the years to recover the famous call sign but none bore fruit... until now.

Several months ago the current KPH license holder made high level diplomatic contact with MRHS president Richard Dillman.  The proposal placed on the table was that the KPH and KFS licenses would be modified to show an additional transmit location at Bolinas, CA with an additional control point at Point Reyes.  In other words... KPH would return home just as Little Davey Sarnoff and Frank Geisel intended!

After a liberal application of smelling salts Dillman quickly recovered from his deep swoon and replied that yes, the MRHS would be very interested in such a proposal. The details were placed before the MRHS Board of Directors and authorization was given for Dillman to open official negotiations.  A Memorandum of Understanding was drawn up and signed.  An application for the modification of the KPH and KFS licenses was submitted to the FCC. 

MRHS members watched the progress of the applications through the halls fo the FCC like vultures watching a ripening dead skunk.  Earlier this week both applications were approved to great huzzahs all around.

> What Does This Mean?
The approval of the license modifications by the FCC means that the transmitters at Bolinas can be shifted back to their original KPH frequencies.  Future MRHS commercial operations will be carried out on these frequencies under the KPH call sign.

> When Will The Change Occur? 
 
The crack MRHS Transmitter Department under the baton of Transmitter Supervisor Steve Hawes will begin the process of shifting the transmitters to the KPH frequencies.  The transmitters now on KSM frequencies still retain their original KPH frequencies so the process may involve "just" throwing a switch on the exciters back to the KPH position, re-tuning the transmitters and re-tuning the antennas.  As simple as this may sound we have found by experience that no operation of this size is as easy as it seems.  So we expect the unexpected as we progress with the frequency shift.  However the Transmitter Department has proven more than once that its personnel are up to any task so it is with full confidence that we anticipate ultimate success.

Plenty of notice will be given of the frequency shift along with a list of the new frequencies.   Be sure to watch for following issues of the Newsletter with full details.

> Celebratory Event Planned
We plan to hold a celebratory public event on the scale of Night of Nights on the day that we officially cut over to the KPH frequencies and begin using the KPH call sign.  We hope to have as many KPH veterans on hand as possible to participate in this historic event. Keep a close watch on following issues of the Newsletter for full details of the date and time of this event.

> What's This About KFS?
Along with the KPH license, the license for KFS was modified to show an additional transmit location at Bolinas and a control point at Point Reyes.  Selected KFS frequencies will be activated as the availability of transmitters and antennas permit.  Full details will be given in following issues of the Newsletter.

> What about KSM?
The MRHS will continue as the licensee of KSM.  In the event that we are no longer able to use the KPH frequencies (see below) will revert back to the KSM frequencies and continue commercial operations under that call.

From Kim Andrew Elliott:


Hello friends,

WRMI, Radio Miami International, will broadcast a special program showcasing digital text and images via analog shortwave radio. This will be transmitted nine times from Saturday through Tuesday. Details and schedule: http://voaradiogram.net/post/148784430842/wrmi-will-showcase-digital-modes-via-analog-radio.   

Based on your reports, last weekend's Thor25x4 performed well, but not as well as our standard MFSK32, which is faster. Thor25x4 does have an interesting sound. It reminded me of the 1970s synthpop instrumental hit "Popcorn," so I included that tune in the show.

[It does sound really, really cool. -Hugh]

This weekend, VOA Radiogram will be all MFSK32. A VOA News video will be presented, via the Internet with the help of Flmsg. Instructions on how to use Flmsg are included in the post about the WRMI special broadcasts.

Here is the lineup for VOA Radiogram, program 176, 13-14 August 2016, all in MFSK32 centered in 1500 Hz:

 1:34  Program preview
 2:54  Pinatubo eruption hid rate of sea level rise*
 8:58  Do black holes have black door?*
12:49  No new stars at Milky Way's center*

VOA Radiogram for August 6-7

From Kim Andrew Elliott:

Hello friends,

Last week's html transmission using Flwrap, or cut/paste as a Plan B, was successful among listeners in many parts of the world. One example was from New Zealand: https://twitter.com/VOARadiogram/status/761559631135141889 .  If you're interesting in more html pages via shortwave, please let me know.


[I consider it an interesting demonstration of capability that would otherwise go unnoticed.  As amateurs, this is what we do.  IP routed content might be sensitive in target areas, but everyone has a browser for local files.  -Hugh]


This weekend's broadcast will not include an html segment. It will, however, include a VOA News story in Thor25x4. This mode is interesting because of its 2-second interleave. Thor25x4 might be able to resist fading, if it occurs this weekend. (We tried Thor25x4 in program 52, 29-30 March 2014, with good results.)

[It will fade here.  As a sub-optimal path from NC to CA, this is what it does. These are always good experiments. -Hugh]


Here is the lineup for VOA Radiogram, program 175, 6-7 August 2016, all in MFSK32 except where noted:


 1:32  Program preview
 2:52  Life in the deep Pacific*
12:49  Private US company plans moon shot*
17:18  Thor25x4: Io atmosphere collapses in Jupiter's shadow**
22:17  MFSK32: Io image
24:34  Special broadcasts by Club Diexistas de la Amistad
26:10  Closing announcements

MARS Sets Interoperability Communications Exercise for August 15

From ARRL Letter:

US Department of Defense (DOD)

Military Auxiliary Radio Service (MARS) operators in the US, Germany, and Japan, will take part in an interoperability communications exercise on Monday, August 15, from 1200 UTC to 2359 UTC. The focus of the exercise is "to train during a simulated communications-constrained environment using radio-only communication capabilities," MARS said.

Throughout the exercise, MARS operators will reach out to and attempt connect with Amateur Radio operators at the local and regional levels using HF, VHF, and UHF. For the purposes of this exercise, the use of the 60 meter interoperability channels -- dial frequencies 5330.5 and 5346.5 kHz -- are authorized and encouraged. Other bands will be coordinated by MARS members at the local/regional level with their ARES/RACES/club counterparts.

The exercise is tied in with a larger DOD exercise, which will include participation by active duty forces. -- Thanks to Army MARS Program Manager Paul English, WD8DBY

[This larger exercise MIGHT have something to do with NORTHERN STRIKE 2016, which lasts until August 20 in Michigan. -hugh]

Corrected Link for Flwrap

 I think VOA Radiogram used flwrap in the dim past, but if so it had been years.  It works great, once you get and install it.  Unfortunately, the link to the fldigi page on Source Forge did not have flwrap.  After a few minutes of futility, I punted, and decided to JFGI.  Indeed, the Google search took me right to an flwrap page on the same site.  Kim Andrew Elliott quickly posted a corrected link, but for those who didn't get it, I'm passing it along.
-hugh

Hello again,

Yesterday at voaradiogram.net, I posted the wrong link to download Flwrap, the add-on to Fldigi that we will be using this weekend.

The correct link for download is https://sourceforge.net/projects/fldigi/files/flwrap/

The web post has been corrected:

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*

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:

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.

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
26:29  MFSK32/1500 Hz: Closing announcements*

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:
