  • VOA Radiogram, 30-31 Aug 2014: vertical line, Tibetan text

    VOA Radiogram during the weekend of 30-31 August will begin with the transmission of a straight vertical blue line. Some of us experience slant when we decode MFSK images, so this line will help us determine if we have a slant problem.  If your line is slanted, URLs for web pages that might help solve the problem will be provided.

    Near the end of the program will be a brief sample of Tibetan language text. “Chicken tracks” like this should appear in the Fldigi receive pane…

    image

    Copy this line and paste it to a word processor, and the Tibetan text might display correctly. 

    OR: In Fldigi’s Configure > Colors & Fonts: Select the UTF-8 character set, then adjust Rx font to Microsoft Himalaya. Because this is a very small font, adjust the point size to 20. In Linux, the font is Tibetan Machine Uni.

    You can switch to the Himalaya or Tibetan fonts just before the Tibetaan text begins 22:39 into the show. Or use the font to decode the entire program, because it displays adequately in English (at least the Microsoft version).

    Here is the lineup for VOA Radiogram, program 74, 30-31 August 2014:

    MFSK32 centered on 1500 Hz

     1:30  Program preview

     2:31  Vertical line for sound card calibration

     4:18  Neuron loss and insomnia, with image

    14:47  North Korea inspecting TVs from China, with RFA logo

  • Recent videos of VOA Radiogram

    Recent YouTube videos demonstrate remarkable decoding of VOA Radiogram content under adverse reception conditions. In these examples, because of a weak signal, or local noise, or both, the music and voice introduction to the program are generally inaudible, but when the MFSK32 begins, text becomes visible.

    You can watch the decodes in the videos, or decode the shows yourself using the audio.
