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 )

It will be another Flmsg blank form, so an html item will pop up as a new window on your browser. (The large photo will come to your PC via the Internet rather than shortwave.) Reports for this KBC reception to Eric: email@example.com .

And IBC has added MFSK32 transmissions via WRMI in Florida: Friday 0125-0200 UTC on 9955 kHz (Thursday 9:25 pm EDT), part of its 0100-0130 broadcast. And Saturday at 0155-0200 UTC (Friday evening 9:55 pm EDT), on 11580 kHz, part of its 0130-0200 broadcast. See http://ibcradio.webs.com/ for the complete schedule and contact information.
Thank you for a large number of reports from last weekend. There was obviously much interest in the experimental nature of the program. I will start to compile a gallery of images today and hope to send them out by the end of the weekend.
I hope you can tune in and write in this weekend.
