Shortwave Radiogram, 23-25 November 2018

Shortwave Radiogram

Shortwave Radiogram

We had fun last weekend with the waterfall spectrogram of the Arecibo message to outer space. You can access some video examples here. This weekend, Merkouris, who created Arecibo waterfall graphic, will tell us, by way of MFSK64  text, how these spectrograms are created. That will be followed by another graphic representing a famous landmark in Thessaloniki, Greece.

My favorite activity on Shortwave Radiogram is to achieve a good text decode despite difficult conditions. Last Saturday, I was able to decode most of the Olivia 64-2000from Bulgaria, using an SDR in Alberta, despite a barely audible signal. However, I am having much less luck decoding the same 64-2000 from my .wav recording of that same reception.

Videos of last weekend’s Shortwave Radiogram (program 74) are provided by Scott in Ontario (Friday 2030-2100) and Ralf in Germany (Saturday 1400-1430 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

This weekend, MFSK32 and MFSK64 only, with seven images and the  waterfall graphic.

Here is the lineup for Shortwave Radiogram, program 75, 23-25 November 2018, in MFSK modes as noted:
