Last weekendâs experiment with Olivia 64-2000 was very interesting, and lots of fun. The mode did provide successful decodes in conditions where the MFSK32 would have failed. Warren in Arizona described his decode â
I am astounded. Based on your email I received, I set Fldigi to
Olivia 64/2K and set the radio on 11.580 MHz and forgot about it. About 23:35 I decided I had missed the broadcast as I was hearing nothing but background white noise. I had Fldigi minimized so with the idea of shutting it down, I opened it up and was amazed to see text coming in.I listened to the entire broadcast and I could not hear the signal nor see anyof it on the waterfall, yet the text was
printing. There was a lot of fading based on the quality of the copy changing but there were periods of perfect copy and a few sections that were pretty bad.Over-all I would say I had 80-90 percent copy of the entire broadcast.
Of course, the Olivia 64-2000 did not work in all instances.For some listeners,the signal was bad enough that no decode was possible.
We will try more slow modes this weekend. On 3 December, during the
troublesome Shortwave Radiogram transmission Sunday at 2330-2400 (24-S), we will try three slow modes that might succeed where our usual MFSK32 fails. The three modes areMFSK16, MFSK8, and IFKP1.0.
2030:00 Voice introduction
2030:50 MFSK16: India net neutrality*
2041:32 MFSK8: India net neutrality (continued)
2049:21 IFKP1.0: Migrating birds in Israel*
2057:47 MFSK16: Closing announcements

Each mode will be preceded by its RSID and five seconds of silence. The MFSK8, in particular, needs precise tuning of the audio frequency. The IFKP1.0 will require a recent version of Fldigi. And, sorry, IFKP1.0and MFSK8 are not available on TIVAR and AndFlmsg.
The other three transmissions will bein the usual MFSK32. Here is the lineup for Shortwave Radiogram, program 24, 2-3 December 2017, all in MFSK32:
1:29 Program preview
2:37 Ocean's deepest fish*
10:47 Could we run out of sand?*
19:21 Russia looks into separate internet for BRICs*
23:24 Sun's activity steady during solar minimums*
26:50 More SSTV from the ISS
