VOA Radiogram Weekend Schedule

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 in Ontario.
