Shortwave Radiogram, 6-7 Jan 2018

Shortwave Radiogram this weekend is mostly in MFSK32, but it also includes some Thor Micro, an exotic and very slow mode.  This mode might be able to overcome poor reception conditions.   And, with Iran in the news, there will be some Persian text.   Special this weekend will be two test transmissions from WINB in Pennsylvania.   Details: http://swradiogram.net/post/169345937052/shortwave-radiogram-6-7-january-2018-persian …

Shortwave Radiogram, 9-10 Dec

Shortwave Radiogram for the weekend of 9-10 December will mostly be in our usual MFSK32. But there will be one news item in 8PSK-1000F.

The 8PSK-1000F will be transmitted in conjunction with Flamp, which will …
