On VOA Radiogram during the past weekend, we had very good success with the decoding of the Chinese text, in both the MFSK32 and 64. Chinese text as an MFSK64 image was less successful, and it took longer to transmit. MFSK images are nice, but it is MFSK text that gets through in difficult reception conditions.
This weekend, our non-Latin alphabet will be Russian. In Fldigi: Configure > Colors & Fonts > use the pull-down menu, perhaps now set to ASCII, to select the UTF-8 character set.
There will also be several images and another comparison of the MFSK128 and MFSK128L (long interleave) modes.
Here is the lineup for the VOA Radiogram, 23-24 November 2013 (the left column shows the amount of time into the show, while the duration of each item is in parentheses):

Please send reception reports to email@example.com.
Screenshots are audio samples are also appreciated. Audio of VOA Radiogram received during challenging shortwave conditions is especially helpful. Audio in mp3 format is OK.
Thanks for your reports from the past weekend. I have begun responding to them.
I look forward to your emails this weekend.
