VOA Radiogram for February 25-26

Hello friends,

With reception conditions apparently improving, we will take a chance with MFSK64 (240 wpm) for one of our news stories this weekend.

But if reception conditions are poor, we will also transmit one story in MFSK16 (58 wpm).  Tuning for MFSK16 needs to be precise, so if the RSID does not work, I precede it with a 10-second tuning signal.

[We have coronal holes, again.  Could go either way. -Hugh]

So this will be a weekend to compare MFSK16, 32, and 64, including one image transmitted in both MFSK64 and 32, and another image transmitted in both MFSK16 and 32.   

Here is the lineup for VOA Radiogram, program 204, 25-26 February 2017, all in MFSK with baud rates as noted:

 1:59 MFSK32: Program preview
 3:10 MFSK64: Astronomers discover "new earths"*
 8:06 MFSK32: Image* and HAARP experiment*
16:28 MFSK16: Arctic seed vault*
22:44 MFSK32: Image* and closing announcements*

Please send reception reports to radiogram@voanews.com.

PS: A few operating notes:
  • For best Olivia 64-2000 performance, turn Fldigi's squelch (SQL) off.
  • The RSID at 1500 Hz sometimes mixes with the transmitter hum, most noticeable at 360 Hz, to move your receive audio frequency down to 1140 Hz, resulting in no decode. To prevent this, in Fldigi: Configure > IDs  > RsID > unselect Searches passband.  Your center audio frequency will wander no more than +/- 200 Hz.
  • Fldigi automatically saves your decoded MFSK images as png files in the folder \fldigi.files\images\ (in Windows; folder names might be different with other operating systems). You can attach those png files with your reception report.

VOA Radiogram for 18-19 February

At the top of his post, Kim noted the irony of the North Carolina transmitter turning off in the middle of an image showing Radio Australia turning off the transmitter for the last time.  Right after the finger on the button was copied all over the planet, the VOA signal went away. The difference, of course, is that the VOA came back. Those of us who have known and loved R. Australia since we were kids with $40 radios are most unhappy that it didn't.  -Hugh

From Kim Andrew Elliott:


Hello friends,

Last weekend, we marked World Radio Day with a malfunction of the radio transmitter on 17580 kHz, during the time that the World Radio Day logo should have been broadcast.  Other than that, we had a good weekend of reception and decoding!

For a good example of Olivia 64-2000 performing well despite poor reception, try decoding from this audio that I recorded from an SDR in Australia: http://voaradiogram.net/post/157100458412/voa-radiogram-olivia-64-2000-received-in-nsw

This weekend, we will again transmit an excerpt of text in a non-Latin Alphabet. This time it will be Ukrainian. Use the UTF-8 character set, which, in Fldigi, you can adjust (if necessary) via Configure > Colors & Fonts.

Here is the lineup for VOA Radiogram, program 203, 18-19 February 2017, all in MFSK32 except where noted:

 1:50  Program preview
 3:17  Trump Administration sued over bumble bee protection*
 9:18  India rocket launches 104 satellites*
16:09  Olivia 64-2000: First white dwarf pulsar discovered
20:44  MFSK32: World Radio Day items from RFE/RL*
23:27  Ukrainian text**
25:59  Closing announcements*

World Radio Day VOA Radiogram for 11-15 February

From Kim Andrew Elliott:

Hello friends,

Happy World Radio Day!  World Radio Day will be Monday, 13 February, and it will be mentioned this weekend on VOA Radiogram.

Also this weekend, we will transmit samples of text in Chinese, Russian, and Persian. For these alphabets to display correctly, Fldigi should be configured to the UTF-8 character set (Configure > Colors & Fonts > adjust Rx/Tx Character set to UTF-8, if it is not there already). Your operating system might also need font support for non-Western languages. If the Chinese, Russian, or Persian text is seen as a series of boxes in the Fldigi receive pane, copy and past those boxes to a word processor, and the text might display correctly. At the bottom of this email is a picture off what the received text in the three languages should look like.

There will be four MFSK32 images this weekend, but they will not be transmitted until the second half of the show.

Here is the lineup for VOA Radiogram, program 202, 11-15 February 2017, all in MFSK32 except where noted:

 1:45  Program preview
 3:05  China to vet online content and services
 6:11  Experiment with non-Latin alphabets**
10:17  Olivia 64-2000: ESA to help NASA
15:53  MFSK32: SSTV from the International Space Station*
19:58  Video of Radio Australia shortwave shutdown*
22:30  World Radio Day*
26:41  Closing announcements

New, loud, Russian marker appears on 4020 kHz

The latest in a long of line of Russian funny noises has appeared as an apparent channel marker on 4020 kHz. This one sounds a lot like one of those small hand-held air horns used on boats. It's in USB, with the usual poorly suppressed lower sideband we've come to associate with these signals.

A honking noise occurs at an interval just under half a second. It's hard to describe.  It's mostly a dropping, harmonic-y tone with a fundamental that briefly settles down to about 420 Hz. Large thump-type transients appear at start and finish.

It will be interesting to see if voice messages appear on the Air Horn, the way they do on the Buzzer, Squeaky Wheel, and Pip.

A recording of this marker has been added to the sound clip section of the Utility Planet web site.  Warning... this one is LOUD!

200th VOA Radiogram 28-29 January

Note expanded schedule!

From Kim Andrew Elliott:

Hello friends,

Last weekend, I had problems with our Outlook contact lists, resulting in some of you receiving two emails, and some VOA Radiogram listeners receiving no email. I’ve reconstructed the mailing lists. If you have previously unsubscribed and are receiving this email again, let me know, and I will delete you again.

DigiDX is taking a few weeks off. VOA Radiogram will be heard during the DigiDX broadcast times on WRMI Florida and IBC Italy. See the expanded schedule below.

The expanded schedule is a good way to celebrate the 200th program of VOA Radiogram this weekend.
