After a few years of inactivity, I am again relaying news about international broadcasting through the Twitter feed @kaedotcom . If you don't have a Twitter account, just visit https://twitter.com/kaedotcom . Most of the Twitter items are eventually also posted to http://www.kimandrewelliott.com .
Last weekend's experiment with Olivia modes, all with 8 tones but bandwidths of 2000, 1000, and 500 Hz, generally showed the narrower bandwidths to provide better performance. Unfortunately, the narrower versions also provide slower text printout. I also noticed that MFSK32 usually provided a better decode than all the Olivia modes. Given that MFSK32 is faster and can transmit images, it becomes evident why it is our favorite mode. If we experience continuously poor reception on Shortwave Radiogram, e.g. if someone decides to jam to the program, we might look for a slower but more robust mode.
If you were not able to tune in last weekend and want to try decoding the three Olivia modes, as well as the MFSK32, these YouTube videos produced by Shortwave Radiogram listeners are available:

This weekend's Shortwave Radiogram will be all MFSK32, including five images. The show includes news about a new Twitter feed that reports on FCC experimental license applications. Then two items from outer space. And finally a nod to the Winter Olympics taking place in a city whose name I can never remember, let alone spell.
Here is the lineup for Shortwave Radiogram, program 35, 17-18 February 2018, all in MFSK32:
1:32 Program preview
2:38 New Twitter feed tracks FCC experimental licenses*
6:55 Search for an ionosphere for signs of planetary life*
16:58 Astronomers image 40-light-year-wide space donut*
23:12 Olympics image*
25:33 Closing announcements*
