Sorry about the rerun during last weekend’s broadcast Saturday at 1600-1630 UTC broadcast on 9400 kHz. Listeners who did not receive the promised Flamp transmission can decode from audio provided by Roger in Germany and video provided by Scott in Ontario. Another Flamp item will be broadcast this weekend.
Most of this weekend’s Shortwave Radiogram will be in our usual
MFSK32, with four images. But we will also include three 8PSK modes:
8PSK-125FL, 8PSK-250FL, and 8PSK-500F. The RSIDs should switch Fldigi to the
correct modes. If you must change modes manually, note that the first two are
8PSK-125FL (not -125F) and 8PSK-250FL (not -250F). You can read about
the 8PSK modes here. (Sorry, these 8PSK modes are not yet available on
TIVAR or AndFlmsg.)
The 8PSK-500F news item uses Flamp. Download Flamp from here
and read the manual here. Under the Flamp Configure menu, select “Auto sync
flamp to fldigi mode selector.” This will force Flamp to use whatever mode
Fldigi is using. Make sure Flamp is running before the 8PSK-500L transmission
begins.
This time we will use smaller blocks with Flamp, to improve the
chances that the file is received 100%. There will be 25 blocks of 240 bytes
each, transmitted four times. If the file is received 100%, click Flamp’s File
> Folders > rx, and the file China_internet_conference.txt should be
found in the folder for the date of reception.
If possible, record your reception. You can try to decode the 8PSK
items, including the one in Flamp, several times. Experiment with different
audio players (Windows versus VLC, etc) and different equalizer settings,
compressors, and other audio tricks.
The Slow
Show. This weekend, the broadcast Sunday at 2330-2400 UTC, providing
poor reception in most parts of the world as we approach the winter solstice,
will entirely be in the Olivia 128-2000 mode. This is a very slow mode, only 17
wpm, but it might be able to overcome difficult conditions. Even if you cannot
hear the tones or see a trace on your waterfall, you might still be able to
decode the text. Make sure that Fldigi’s squelch (SQL) is off. If your
reception is bad, this could be interesting. If it is good, this will be as
much fun as watching paint dry.
There is no RSID for Olivia 128-2000, so you need to set it
manually. Under the Fldigi Op Mod menu, select Olivia > Custom: then dial up
a bandwidth of 2000 Hz, with 128 Tones. Again, record your reception if
possible. You can then experiment with the integration period in that
same menu. If you increase the number of FEC blocks, your decode might improve.
It will also increase the delay time between hearing the tones and seeing the
text print out, but this is less of a problem in receiving a broadcast than in
an amateur radio QSO. Read about Olivia, including the integration period, here. Also try different audio players and settings. (Sorry
again: TIVAR and AndFlmsg do not include Olivia 128-2000.)
