Interesting Participatory VOA Radiogram for April 12-13

If you couldn't hear the first VOA sked last weekend, on 5745 at 0930 UTC, it wasn't your equipment. Due to scheduling mixups, it was never broadcast.

From Kim Andrew Elliott:

Hello friends,

After last weekend's schedule mishap, the VOA Radiogram transmissions should be back to their regular times and frequencies this weekend:

All transmissions via North Carolina

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. (The RSID will help unlock the mystery of the mystery mode.)

You can decode both the MFSK32 and the other 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. It will probably be a few Hz above or below 2300 Hz. The content 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 indicated):

 1:43  Program preview
 2:58  Mystery mode starts centered on 2300 Hz
 4:44  Survey of trust in the Internet, with image
13:00  Intel's use of non-conflict minerals, with image
19:15  US Navy developing fuel from seawater, with image
24:19  VOA Spanish on "cardio," with VOA Voz de América logo
27:10  Closing announcements

Please send reception reports to radiogram@voanews.com

Thanks for your reports to VOA Radiogram from the past weekend. I will begin to answer them today. I look forward to hearing from you this weekend.
