Hello friends,

Put on your official Shortwave Radiogram white lab coats, because we will be experimenting this week on program 452.

After the usual MFSK32 and before the MFSK64, there will be a brief message in Olivia 64-2000 about «Extreme Shortwave,» a new project that will be a companion to Shortwave Radiogram. 

To receive Olivia 64-2000 (64 tones, 2000 Hz wide), make sure the SQL (squelch) in the bottom right of Fldigi is off. Also, the bandwidth on your receiver should be 2500 Hz if you tune in using sideband, or 5000 Hz with AM. (This should not be a problem with most receivers.) And note that the characters from the Olivia 64-2000 will not appear on your display until a couple of seconds after the tones are heard.

If you tune in a Shortwave Radiogram transmission in which reception is poor — even if inadequate for MFSK32 text — good! It will be a great test for the Olivia 64-2000. Reception might be so bad that you can’t understand a word of my voice introduction. Even if that happens, stay tuned.

You probably will need to set the mode to Olivia 64-2000 manually before it begins at 6 minutes, 18 seconds into the program. At that point, you might see the Olivia 64-2000 text on your display even if reception and decoding are unsuccessful during the rest of the broadcast   

A video of last week’s Shortwave Radiogram (program 451) is provided by Scott in Ontario (Wednesday 1330 UTC). The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany.
