Last weekend's experiment with the transmission of an html-formatted VOA News story resulted in many successful decodes, but also several failures. The failures were mainly due to the base64 compression of the transmitted file, which requires all of the received characters to be received correctly. On shortwave, as we know, perfection is often elusive.
This weekend, we will transmit another html-formatted VOA News story. This time we will use Flwrap, another Fldigi add-on program. See details and instructions here: http://voaradiogram.net/post/148147415237/experimenting-with-web-pages-via-shortwave .
Because Flwrap does not require the html to be compressed, if the checksum fails, you have a Plan B: Copy the text in the Fldigi from <html> through </html>, paste it to a text editor (like Notepad), save it as an .html file, and open it in a browser.
Here is the lineup for VOA Radiogram, program 174, 30-31 July 2016, all in MFSK32 centered on 1500 Hz:
