Hello friends,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 *** 8:31 MFSK32: Court ruling on Turkey's blocking of YouTube * 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<http://www.va3rom.com/> in Ontario. Please send reception reports to radiog...@voanews.com.
