Shortwave Radiogram, weekend schedule


Hello friends,

It's icy here in northern Virginia, but not bad compared to many places in North America. We still have electricity, so I was able to produce and upload program 192. My wire antennas are still up, except for the 40-meter inverted V that fell during the previous ice storm. To listeners not reading this for lack of electricity, I wish you a speedy recovery. And, in the meantime, enjoy the quiet radio conditions.

Videos of last weekend's Shortwave Radiogram (program 191) are provided by Scott in Ontario (Friday 1300 UTC), Francisco in Brazil (Saturday 0330 UTC using TIVAR), Ralf in Germany, and Frigid RF in Virginia (both Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. The analysis is prepared by Roger in Germany.

This weekend's show includes a VOA Khmer story about Cambodia developing a new internet firewall. This will be followed by an excerpt of the same story in the Khmer language. Khmer characters are very complicated, as will be evident when you see them printing. If you see rectangles instead of Khmer characters, copy those rectangles to a word processor, and you might see the correct Khmer words. Khmer-language printout requires the UTF-8 character set, but this now defaults in Fldigi and TIVAR.

Our modes for this weekend's show are the usual MFSK32 and MFSK64, with nine MFSK64 images.   

Here is the lineup for Shortwave Radiogram, program 192, 19-21 February 2021, in MFSK modes as noted:

 1:42  MFSK32: Program preview
 2:47  Lead-based anode for lithium batteries doubles the storage
 6:45  MFSK64: Cambodia to Create Internet Firewall
11:47  Khmer-language text
13:59  This week's images
28:35  MFSK32: Closing announcements

“This is a Music Show” Most of the show is a music show, but the host transmits some MFSK text and image near the end of the broadcast.

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 1230 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 , or tweet to @SWRadiogram, and I will let them know you are tuned in. USEast NBEMS Net: Please also note the USEast NBEMS Net, Thursdays 0000 UTC (Wednesdays 7 pm EST) on 3536 kHz USB.
Thanks for your reception reports!
