VOA Radiogram, 12-13 April 2014, includes mystery mode

VOA Radiogram, for the weekend of 12-13 April 2014, will be all MFSK32 centered on 1500 Hz, but there will also be a mystery mode transmitted simultaneously at an audio frequency of 2300 Hz. (An RSID will help unlock the mystery of the mystery mode.)

You can decode both the MFSK32 and the mystery mode by 1) running two instances of Fldigi, 2) running Fldigi and another decoding software such as MultiPSK or DM780, or 3) recording the show and decoding the mystery mode later.

The audio frequency of the mystery mode needs to be tuned very precisely. The content of the mystery mode is the VOA Radiogram email address, website URL, and schedule, transmitted over and over, so you will have plenty of time to achieve a successful decode.

One of the MFSK32 VOA news items will be in Spanish. You will need the UTF-8 characters for the accented letters to display correctly. Find the UTF-8 setting via  Configure > Colors and Fonts.  

Here is the lineup for VOA Radiogram, program 54, 12-13 April 2014 (all MFSK32 centered on 1500 Hz except where noted):
