  • YouTube videos of VOA Radiogram from the weekend on 7-8 Sept 2013

    IK0DWN in Italy produced this YouTube video of his reception on 7 September 2013 at 1600-1630 UTC on 17860. There is no audio with this video, but the screen capture is very good. Everything was decoded successfully except the MFSK128/Flamp, which may not have been attempted

    Tim, K0RUS, in Colorado recorded his reception of the same transmission, and it does have audio. You can hear, however, that Tim’s reception suffered from deep fades and local noise…

    This actually was a good test of the ability of the modes to handle interference. Not surprisingly, much of the content failed to decode. What is amazing is what did decode, despite the adverse conditions:

    1. Both MFSK16 transmissions were at least 90% – a real testament to the robustness of MFSK16.
    2. The Spanish Flmsg item rendered.
    3. The MFSK128 Flamp item came through on the first pass. A most unlikely outcome for such a fast mode.
    4. The second and third MFSK32 images looked fairly good given the conditions.
    5. The second MFSK64 story was at least 75%.

    Finally, this YouTube produced by Gilles in Montreal is from reception on 8 September 2013 at 0230-0300 UTC on 5745 kHz:
