This weekend on VOA Radiogram, we will conduct one more (for now) QR code experiments. The VOA Radiogram URL will be transmitted as 1) plain text, 2) as a QR code via MFSK32 image, 3) as UTF-8 block elements -- those things that look like this: ▙ ▚ ▛ . A QR code transmitted this way will benefit from the error correction inherent in any MFSK text transmission. You will need the UTF-8 character set (Fldigi: Configure > Colors & Fonts > Rx/Tx Character set).
The transmission of the QR code as UTF-8 in MFSK32 is slow, so after the MFSK32, the QR code will be sent in MFSK64 for increased speed.
Here is the lineup for VOA Radiogram, program 140, 5-6 December 2015, all in MFSK32 except
where noted:
1:31 Program preview
2:58 Experiments with QR codes **
7:13 MFSK64: QR code ***

12:44 Solar-powered plane will resume flight *
18:53 Prehistoric beast looks like Star Wars queen *
24:55 Closing announcements ****
* With image
** The QR codes using block element require the UTF-8 character set. In Fldigi: Configure > Colors & Fonts > Rx/Tx Character set - set to UTF-8.
*** After the MFSK64 RSID, there will be 10 seconds of silence in case the mode must be changed manually.
**** After the closing announcement, a custom QR code made by Robert in Ontario.
