Shortwave Radiogram, 12-15 October 2018

Shortwave Radiogram

Shortwave Radiogram

Last weekend’s slant test produced interesting results. Please note that your sound card might be perfectly calibrated, but slant in MFSK32 images will still occur. This is because of disagreements in the sampling rates of my sound card, the sound card at the shortwave broadcaster, the sound card at any remote SDR you might use,  and your sound card. If you use an external digital recorder, that adds another factor that can cause slant. For this reason a slant adjustment at the beginning of each broadcast might be a good idea in the future.

Videos of last weekend’s Shortwave Radiogram (program 68) are provided by Scott in Ontario (Friday 2030 UTC), Ralf in Germany (Saturday 1600 UTC), and 2010 DFS in Japan (Monday 0800 UTC). The audio archive is maintained by Mark in the UK. Analysis of last weekend’s Shortwave Radiogram and other programs transmitting text and images is prepared by Roger in Germany.

This weekend we will transmit the usual combination of MFSK32, 128, and 64, with nine MFSK images.
