Shortwave Radiogram, 8-10 February 2019: Digital modes with your choice of manual or automatic

Shortwave Radiogram

A reminder that the Winter SWL Fest will be 28 February-2 March at
Plymouth Meeting, Pennsylvania (near Philadelphia). Information at swlfest.com. I will be there to demonstrate Shortwave Radiogram.

SSTV will be transmitted this weekend
from the International Space Station, from 1400 UTC today (Friday)
through Sunday, 10 February, at 1830 UTC. The frequency is 145.8 MHz
(FM). The SSTV mode will be PD120. Use MMSSTV or the receive-only RXSSTV or similar software to decode. You can track the location of the ISS here. During these events, I keep a radio tuned to 145.8 MHz FM and MMSSTV running, and periodically check for any results.

Last weekend’s experiment with multiple modes, some very fast, via
WINB’s DRM transmitter was complicated by generally poor conditions. We will transmit the same content today
(Friday) at 1500-1530 UTC on 13690 kHz from WINB in Pennsylvania. For
details about the program and information about receiving and decoding
the WINB DRM broadcast, see this post at swradiogram.net. (Expect the PSK-1000R to fail!)

Also at swradiogram.net is this audio
of reception in Alberta of the MFSK32 text, Saturday 1400-1430 UTC,
9400 kHz from Bulgaria.You can decode from this example showing how
MFSK32 can communicate even in very difficult conditions.

Videos of last weekend’s Shortwave Radiogram (program  ) are provided by youngalientype (not sure of his location) with the first ten minutes of the DRM transmission Friday at 1500 UTC, Scott in Ontario (Friday 2030 UTC),  Ralf in Germany (Saturday 1400 UTC), and a first effort by Adrian in Ireland (Sunday 2330 UTC), battling some heavy noise interference. The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Shortwave Radiogram this weekend will include a brief segment of Olivia 64-2000.
This robust mode might provide a good decode even in very poor
conditions, where the MFSK modes are unsuccessful. Examples would
include Bulgaria on 9400 kHz direct to North America, and WINB on 9265
in the eastern USA, within the skip zone. Even if you are not hearing or
decoding anything else, manually set the mode to Olivia 64-2000 and, at
seven minutes into the broadcast, see if there are any results. For
best performance, turn the squelch (SQL) off.

* special content this weekend.

Slow Scan Radio transmits SSTV images and text modes
Saturdays at 1300-1330 UTC on 6070 kHz and 7440 kHz via Channel 292 in
Germany – according to the latest schedule information I have. The
website is http://www.slowscanradio.com. Reception reports to x@xdv.me.

The Mighty KBC transmits to Europe Saturdays at
1300-1400 UTC on 11600 kHz from Bulgaria, with the minute of MFSK at
about 1330 UTC (if you are outside of Europe, listen via
websdr.ewi.utwente.nl:8901/ ). And to North America Sundays at 0000-0200
UTC (Saturday 7-9 pm EST) on 5960 kHz, via Germany. The minute of MFSK is at about 0130 UTC.  Reports to Eric: themightykbc@gmail.com . See also http://www.kbcradio.eu/ and https://www.facebook.com/TheMightyKbc/.

New York and Pennsylvania NBEMS nets. Most weekends, as
KD9XB, I check in to the New York NBEMS (Narrow Band Emergency
Messaging Software) net Saturday at 1300 UTC on 3584 kHz USB, and the
Pennsylvania NBEMS net Sunday at 1300 UTC on 3583 kHz USB. Check-ins are
in Thor 22, and messages are in MFSK32. Messages usually use the Flmsg
add-on to Fldigi. If you are a radio amateur in eastern North America,
feel free to check in. Outside the region, use an SDR in the eastern USA
to tune in and decode. You do not need Flmsg to check in, and most of
the messages can be read without Flmsg. If you can decode the net, send
me an email to radiogram@verizon.net , or tweet to @SWRadiogram , and I
will let them know you are tuned in.
