Apologies for the late start last weekend of the Friday 1300-1300 UTC
broadcast on 15770 kHz. When it finally came on the air about halfway in
to the half-hour, reception was great here in the mid-Atlantic USA. The
Saturday 1330-1400 UTC show, also on 15770, was transmitted in its
entirety, but reception in North America was not good. It did reach
Europe, however. Such is the daily variability of shortwave.
We had fun last week with the two exotic modes. The Hell 80 was visible
most places. It’s not very practical, but it interesting to try
occasionally. The 32xPSK63R (1760 wpm!) failed to achieve a 100% decode
in most places, as expected. There, however, some successes. Most were
one hop from the transmitter. Some were as far as California and Europe
(see this example from France).
The 32xPSK63R mode might be useful for reliable, short-hop circuits in
which a large amount of content – such as a formatted web page – needs
to be sent without taking too much time.
Videos of last weekend’s Shortwave Radiogram (program 164) are provided by Scott in Ontario (Saturday 1330 UTC), Brijesh E.P using an SDR in Texas (Sunday 0800 UTC on 5850 kHz), and Ralf in Germany (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.
This weekend’s show is in the usual MFSK32 and MFSK64. with ten images (1 x MFSK32 and 9 x MFSK64).

the broadcast. It’s transmitted on WRMI, Thursdays at 0200-0300 UTC on
5850 kHz (Wednesday evening in the Americas) and a new time also on

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 1200 UTC on 3584 kHz USB, and the
Pennsylvania NBEMS net Sunday at 1200 UTC on 3583 kHz USB (with
out-of-state check-ins now starting at 1130 UTC). Check-ins are usually
in Thor 22, and messages are in MFSK32. Messages generally 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 email@example.com , or tweet to @SWRadiogram , and I
will let them know you are tuned in. USEast NBEMS Net: Please also note the USEast NBEMS Net, Wednesdays 2300 UTC (7 pm EDT) on 3536 kHz USB.
