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:

** 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.
