Hello friends,
Sorry about the missing Shortwave Radiogram last Friday at 2030-2100
UTC (Brother Stair was heard on WRMI, instead). That was due to an uploading
error on my part.
Videos of last weekend’s Shortwave Radiogram (program 64) have
been provided by DFS in
Japan and Ralf in
Germany (both Saturday 1600 UTC) and by Scott in Ontario
(Sunday 2330 UTC). Excerpts of the Saturday 1600 UTC show are presented in
videos by DFS in Japan
(outdoor reception) and SWLDXBulgaria.
Mark
in the UK maintains an audio archive. Roger in Germany produced his analysis.
Last weekend, I noticed "positive slope" in many of the
decoded images from Space Line in Bulgaria. On the other hand, "negative
slope" is often observed with images from WRMI. This may have to do with
the sound cards used to play out the Shortwave Radiogram mp3 file at each of
these broadcast facilities.
During the transmission of the first two images of this weekend’s
Shortwave Radiogram, observe the vertical lines for slant. If there is slant, in Fldigi: Configure >
Sound Card > Settings > Corrections -- adjust the Rx ppm.
If the lines are slanting to the right as they move downward
(negative slope), enter 100 in the space, then make smaller adjustments until
the lines become completely vertical.
(It’s faster to type in 100 than to use the up-down arrows.)
If the lines are slanting to the left as they move downward
(positive slope), enter -100 in the space, and adjust from there to achieve a
completely vertical lines.
Slant with a negative slope looks like this. Use a positive value
of ppm Rx correction to make it straight:
--------

Slant with a positive slope looks like this. Use a negative value
of ppm Rx correction to make it straight:

When you have made your adjustment, click Close but not Save,
because you might need another adjustment for future broadcasts.
The image of the lines will be transmitted twice.
For more about slant in MFSK images, see this page from the archive of the VOA Radiogram website.
