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.
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 thepost 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*
16:31  Method to convert CO2 to fuel
