Shortwave Radiogram weekend schedules

Shortwave Radiogram

Hello friends,

Thanks to everyone who participated in last weekend’s exercise to eliminate slant in MFSK images.  Many of you did not see any slant to begin with. This usually happens with direct reception. But if reception is through an SDR, another sound card is involved, increasing the chance for a clash in the sampling rates. This tweet shows how I was able to eliminate the slant during the first image of vertical lines, so that the lines were perfectly (at least to my eye) vertical during the second image.

Recording Shortwave Radiogram gives you another opportunity to eliminate any slant in your MFSK images. You can make the RX ppm adjustment in Fldigi, or use the Audacity software to change the speed of your recording. A (+)100 ppm adjustment in Fldigi would be the same as a (+).01% adjustment in the speed of your playback.

Videos of last weekend’s Shortwave Radiogram are provided by Scott in Ontario(Friday 2030 UTC),  2010DFS in Japan(Saturday 1600 UTC) (see also his Twitter thread showing an inexpensive D-808 receiver connected to a Beverage antenna; his use of a voice recorder might have added additional slant, which he corrected in time for the second image of vertical lines), by Ralf in Germany (Saturday 1600 UTC). Mark in the UKmaintains an audio archive. Roger in Germany provided analysis.

This weekend’s Shortwave Radiogram will be in our usual combination of MFSK32, MFSK128, and MFSK64, with maybe a mystery mode (and mystery image – to save it, click Save) during the closing music. The show will include eight MFSK images.
