On VOA Radiogram during the weekend of 21-22 December 2013, our experiment with shifting the center frequency of MFSK64 images from 1500 Hz to 1700 Hz resulted in improvements that were, at best, subtle.

This weekend, 28-29 December, begins our new broadcast Saturday at 0930-1000 UTC on 5745 kHz. The time is inconveniently early for listeners in the Americas, but it might be audible and decodable in the Asia-Pacific region and in northern Europe. Expecting that reception conditions might be marginal in these parts of the world, the program will include a VOA News item in the robust MFSK16 mode.

Because of the addition of the new transmission had to be budget-neutral, the VOA Radiogram broadcast Sunday at 1300-1330 UTC on 6095 kHz is, unfortunately, discontinued.

Here is the lineup for program 39 of VOA Radiogram, 28-29 December 2013:

  1:38  MFSK16: Program preview
  3:30  MFSK16: Supercomputer for bioresearch
  8:08  MFSK32: ESA Gaia satellite, with image
13:58  MFSK32: Scientists predicted earthquake
21:01  MFSK64/Flmsg: Novice farmers, followed by image
25:48  MFSK32: Closing announcements
