Dezider Monoš, OM5NA, in Slovakia, produced two YouTube videos of his VOA Radiogram reception during the weekend of 30-31 March 2013.

The first is 30 March 2013, 1600 UTC, 17860 kHz, showing his reception of MFSK64, PSKR500, MFSK128, and the two MFSK32 images:

The second is 31 March 2013, 0230 UTC (4:30 am in Slovakia!), 5745 kHz, comparing PSKR500 and MFSK128 (Dezider declares MFSK128 to be the winner):

Dezider also provides these images, comparing reception on three transmissions:

And he provided this spectral view of his reception of the three frequencies: 

Radio 700 Kurzwelledienst

Radio 700 Kurzwelledienst in Euskirchen, Germany, a shortwave broadcaster using 1-kilowatt transmitters, is experimenting daily with the PSKR250 digital text mode centered on 2000 Hz:

0557 UTC on 6005 and 7310 kHz
1555 UTC on 7310 kHz
1655 UTC on 6005 kHz

See this YouTube video by DG0JBA showing the decoding of a Radio 700 PSKR250 transmission.

PCJ Radio International

Taiwan-based PCJ Radio International will conduct another digital text experiment via WRMI, Radio Miami International, UTC 7 April 2013, 0227-0230, using the MFSK32 mode. WRMI is on 9955 kHz. This weekend’s message will be in Spanish.

The Mighty KBC

Netherlands-based The Mighty KBC will, as usual, include digital and images in its North America broadcast, Sunday 7 April 2013 at 0000-0200 UTC on 7375 kHz via Nauen, Germany (125 kW). At about 0133 UTC, MT63-2000 (long interleave) will be centered on 1500 Hz. At just before 0200 UTC, an image in MFSK32 will be centered on 1500 Hz.

Merkouris Gogos in Thessaloniki, Greece reported perfect decode of the very fast (480 wpm) MFSK 128 mode on 31 March 2013 at 1930 UTC on 15670:

Mike Stapp in Minneapolis had perfect decode of MFSK 128, same time, same frequency:

It’s remarkable that one IBB transmitter in North Carolina, on one frequency, achieved perfectly decoded digital text at locations 8000 km apart.

Some listeners used inexpensive portable radios to receive VOA Radiogram over the weekend. And they were able to achieve successful decodes of the text.

Andy Lawendel in Milan, Italy used a Tecsun PL660…

For this flawless decode of MFSK32 during the Sunday 1930 UTC broadcast:

In northern Virginia, my Tecsun R9700D, with analog tuning and whip antenna…

…managed 100% decode of the fast and finicky MFSK128 mode during the 1300 UTC broadcast:

Daniel Kaehler, in Germany near Kiel, used a Sangean ATS-909 for this perfect printout of the Flmsg story during the Sunday 1930 UTC airplay:

If you missed VOA Radiogram over the weekend, Chris near Toronto has recorded and posted two entire weekend airplays, along with audio from The Mighty KBC digital text tests:

Chris also shows what VOA Radiogram looks like on his WinRadio display just as the program signs on at 0230 UTC on 5745 kHz:

And later in the broadcast, at 0239, when digital text is being transmitted, centered on 2500 Hz: 

Mark Webber, W4MRW, produced some excellent YouTube videos of this weekend’s digital text via analog shortwave broadcast. Each includes audio, the Fldigi printout, and the Flex-3000 SDR spectrum display.

On the Mighty KBC, 31 March 2013, 0133 UTC, 7375 kHz, an MFSK128 transmission resulted in about 95% copy in northern Virginia. Not bad for a 480 WPM mode. Transmitting it twice or three times with Flamp would likely result in 100% copy:

See also great YouTube video by Mark Webber.

Uwe Wolk in Germany also had 100% copy of the Flmsg news story in MFSK64 during the 1600 UTC airplay on 17860 kHz:

Also excellent MFSK32 images:

Merkouris Gogos of Thessaloniki, Greece had 100% or 95% copy of all of the modes at 1600 UTC, including 100% of the very fast MFSK128.

Here is his reception of the MFSK64 transmission is Flmsg format:
