Hello friends,
Last weekend's Shortwave Radiogram was a reminder of the ability of MFSK16 to provide a correct decode even in difficult shortwave conditions. Thank you for your reception reports, especially listeners in Japan who decoded, or attempted to decode, the excerpt of Japanese text. (See this example from SakaƩ-san in Joetsu-City, Niigata Prefecture.) Sometimes, even the MFSK16 was not able to overcome the challenges of RF interference in urban locations, especially with the transmitter 12000 km away.
The Saturday 0230-0300 UTC transmission on 9265 kHz from WINB Pennsylvania continues to have a wide footprint, as seen in this tweet showing successful decode of the Japanese text simultaneously in Hungary and Hawaii. And during the Sunday 2330-2400 UTC show on 7780 kHz from WRMI Florida, the Japanese text was successfully decoded half way around the world in Perth, Western Australia. Hear the audio (from which you can decode) and see the decoded text here. Also, Roger in Germany made this sonogram of the Perth SDR reception.
Videos of last weekend's Shortwave Radiogram (program 97) are provided by Scott on Ontario (Friday 1300 UTC), radio no koe in Japan (excerpt from Friday 1300 UTC received via Italy SDR), also radio no koe (excerpt from Sunday 0800 UTC on 5850 kHz via Maui SDR), and Ralf in Germany (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.
