Hello friends,
I hope you have been able to withstand our stretch of cold and snow (unusual in some places) during the past few days in North America. At our house, the outdoor thermometer showed 10Ā°F/-12Ā°C during the early morning hours — not as bad as many places, but about as cold as we have ever been.
Last week’s experiment with Olivia 64-2000 and Olivia 32-2000 was interesting. It was difficult to find signals poor enough that MFSK32 showed errors, while Olivia 64-2000 was 100% (or nearly so). But I have audio of two examples, which you can access, and from which you can decode. The first is January 19, 0330 UTC, 9265 kHz from WINB Pennsylvania. The signal is very weak because the signal is too close (200 km) to my receiver in northern Virginia.Ā The second is January 19, 2300 UTC, 7570 kHz from WRMI Florida. Here, the reception is challenging via an SDR in Bermuda because Voice of (North) Korea is co-channel and stronger.
A video of last week’s Shortwave Radiogram (program 385) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. (This link now works) Analysis is provided by Roger in Germany. Roger shows us the comparative bandwidths of the MFSK32, Olivia 64-2000, Olivia 32-2000 and MFSK64 …
