Hello friends,
Last weekend’s 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 …
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 any
of 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 are MFSK16, MFSK8, and IFKP
1.0.
2030:00 Voice

2030:50 MFSK16:

2041:32 MFSK8:

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, IFKP1.0 and MFSK8 are not available on TIVAR and
AndFlmsg.
The other
three transmissions will be in the usual MFSK32. Here is the
lineup for Shortwave Radiogram, program 24, 2-3 December 2017, all in MFSK32:
