Hello friends
Thanks to Daz Man in Australia for producing last week's special EasyDRF
transmission. And thanks to everyone who participated by tuning and decoding,
or attempting to decode, whether you were successful or not.
When it worked, the EasyDRF results were dazzling: A fully formatted web page
with links and animation, and no text errors. Also, images that were perfect,
not fuzzy at all, and larger than our typical MFSK images. (See results in
California at the bottom of this email, and more at @SWRadiogram on Twitter.
EasyDRF is derived from HamDRM, the amateur radio version of DRM (Digital Radio
Mondiale). Like broadcast DRM, EasyDRF produces results that are perfect -- or
nothing at all. Thus, in typical shortwave conditions, where our MFSK might
drop a few characters, and the images might be slightly to moderately fuzzy,
EasyDRF may not work. For this reason. we will stay with MFSK32 and MFSK64, and
occasionally other modes, on Shortwave Radiogram.
Experiments with EasyDRF should definitely continue, in separate time slots. It
will work well on shortwave paths where reception is usually good, e.g. UK to
western Europe, or southern USA to the Midwestern USA and Canada. And it would
be great to try EasyDRF on AM broadcast radio. Do you know of a local AM
station that would be willing to try some experiments? Of course, EasyDRF would
work on FM broadcast radio, as well.
A video of last weekend's Shortwave Radiogram (program 304) is provided by
Scott in Ontario (Friday 1300 UTC). You can decode the EasyDRF from the audio
of his video. His reception allows for the successful decoding of the html and
all but the last two images. Analysis is prepared by Roger in Germany.
Here is the lineup for Shortwave Radiogram, program 305, 18-23 May 2023, back
