Hello
friends,
With reception conditions
apparently improving, we will take a chance with MFSK64 (240 wpm) for one of our
news stories this weekend.
But if reception conditions are
poor, we will also transmit one story in MFSK16 (58 wpm). Tuning for MFSK16
needs to be precise, so if the RSID does not work, I precede it with a 10-second
tuning signal.
So this will be a weekend to
compare MFSK16, 32, and 64, including one image transmitted in both MFSK64 and
32, and another image transmitted in both MFSK16 and 32.
Here is the lineup for VOA
Radiogram, program 204, 25-26 February
2017, all in MFSK with baud rates as noted:
1:59 MFSK32: Program
preview
3:10 MFSK64: Astronomers
discover "new earths"*
8:06 MFSK32: Image* and
HAARP experiment*
16:28 MFSK16: Arctic seed
vault*
22:44 MFSK32: Image* and
closing announcements*
*
with image
Please send reception reports
to radiogram@voanews.com.

Thanks for your reports. I

(especially active just before, during, and after
broadcasts)
- For best Olivia 64-2000 performance, turn Fldigi's
squelch (SQL) off.
- The RSID at 1500 Hz sometimes mixes with the transmitter
hum, most noticeable at 360 Hz, to move your receive audio frequency down to
1140 Hz, resulting in no decode. To prevent this, in Fldigi: Configure > IDs
> RsID > unselect Searches passband. Your center audio frequency
will wander no more than +/- 200 Hz.
- Fldigi automatically saves your decoded MFSK images as
png files in the folder \fldigi.files\images\ (in Windows; folder names might be
different with other operating systems). You can attach those png files with
your reception report.
- The VOA Radiogram Twitter account @VOARadiogram is
especially active before, during, and after the broadcasts. You don't need a
Twitter account: just go to https://twitter.com/voaradiogram and refresh it
occasionally.
