Autumn VOA Radiogram October 1-2
From Kim Andrew Elliott:
Last week, some
listeners heard and decoded MFSK32 transmissions just before and just
after VOA Radiogram Saturday at 1600-1630 UTC on 17580 kHz. The source
of these transmissions is unknown. This Saturday,
please listen (and, if possible, record) on 17580 in the minutes before
1600 UTC and after 1630 UTC to see if the mystery MFSK32 returns.
Last Saturday at 0930 UTC, on 5745 kHz, using the
University of Twente receiver
in the Netherlands, I saw a faint carrier from the North Carolina
transmitter. It’s probably too early in the season to decode from such a
signal, but, if you are in Europe (especially
northern Europe), check this broadcast as winter approaches.
broadcast will be all MFSK32 except for one news item in Olivia 16-1000.
If your reception condition results in errors with the MFSK32, the
Olivia 16-1000 might have fewer errors.
Here is the lineup for VOA Radiogram, program 183, 1-2 October 2016, all in MFSK32 except where noted …

3:04 Lyman-alpha blobs in distant space*
