VOA Radiogram for February 22-23

from Kim Andrew Elliott:
Hello friends,

Last weekend's experiment with the simultaneous transmission of MFSK32 text and an MFSK64 image was fairly successful. We still need to determine the best combination of modes and audio frequencies for simultaneous text and image transmissions.

This weekend we will resume more conventional sequential text and image transmissions. MFSK32, MFSK64L, and MFSK64 will be used.

Here is the lineup for VOA Radiogram, 22-23 February 2014, program 47:

 1:40  MFSK32: Program preview
 2:55  MFSK32: Greetings to WinteRFest in Iowa, with images
 6:03  MFSK32: Winter SWL Fest forums, with image
 7:24  MFSK32: Lasers for space communication, with image
12:09  MFSK64L: Restrictions on Turkish media, with MFSK64 image
19:19  MFSK64: Independent bookstores in USA, with image
26:35  MFSK32: Closing announcements
