  • VOA Radiogram 172: Results of Battle of the Modes and Flmsg

    A busy VOA Radiogram, program 172, during the weekend of 16-17 July 2016, included “The Battle of the 55-wpm Modes” (BPSK63F, MFSK16, and Olivia 8-1000), as well as a formatted html VOA Radiogram schedule transmitted via Flmsg, an add-on to the Fldigi decoder software.

    Tim, K0RUS, produced a YouTube video of VOA Radiogram, 17 July 2016, 0230-0300 UTC, 5745 kHz. In this video, you can see the Battle of the Modes (starting at about 11:10 into the video) and the Flmsg item (starting about 24:05, with the schedule popping up in a new browser window).

    Roger in Germany showed all of the reception of program 172, 16 July 2016, 1600-1630 UTC, 17580 kHz, including the Flmsg:

    Because the html in the Flmsg transmission is all text, with MFSK32’s forward error correction, the web pages were crisp and clear, even if the MFSK32 images were fuzzy. Here’s an example from Frank, VK6FH, in Perth, Western Australia, who tuned in Saturday, 0930-1000 UTC, 5745 kHz, nominally directed to the Caribbean:

    Many examples of perfect html decodes were received from all over the world. Here are two examples from the Saturday 1600-1630 UTC broadcast, 1600-1630 UTC, received by Mike in Washington state (L) and Merkouris in Greece, demonstrating the intercontinental footprint of the North Carolina shortwave transmitter:

    Frank also provided text of his reception of the three modes in the Battle of the Modes. Only MFSK16 was perfect:
