Hello friends,
Last weekend’s experiment with the five 2000-Hz-wide Olivia modes was
interesting and fun. It appeared that Olivia 64-2000, 32-2000, and 16-2000 all 
performed well, even in difficult reception condition. It was not until Olivia 
8-2000 and, more so, 4-2000that errors were seen. At about 75 words per minute, 
Olivia 16-2000 might be a good mode for Shortwave Radiogram,except that it is 
only about 70% as fast as MFSK32 and, unlike MFSK32, it cannot be used to 
transmit images.

If you have recordings of your Olivia mode reception, especially if your decode 
was lessthan 100%, try decoding from your recording after adjusting the 
integration period upward (Op Mode > Olivia > Custom). Read about the 
integration period here and note that the default integration period changes as 
the number of tones changes.Large integration periods can be a problem in 
amateur radio QSOs, because ofthe lag time between transmit and receive, but 
they are less of a problem in a broadcast situation. If you do not have a 
recording, you can use Scott’s video, with some errors seen from the Olivia 
8-2000 and 4-2000 modes.
This weekend Shortwave Radiogram will be all MFSK32. There are two interesting 
stories about North Korea, and one about finding a lost 
NASA satellite. Each of these has animage, and there is a bonus images of 
Wednesday’s “super blue blood moon.”
The broadcast Sunday at 2330 UTC coincides with the kick off of Super Bowl 
LII.If ratings for the big game are down this year, it will be due to 
competition from Shortwave Radiogram.

Here is the lineup for Shortwave Radiogram, program 33,3-5 February 2018, all 
in MFSK32 centered on 1500 Hz:
