Shortwave Radiogram, 5-7 de Marzo 2021

Reception was certainly variable last weekend, with successes and difficulties. Typical shortwave. See results at the Twitter account @SWRadiogram, or point your browser to https://twitter.com/swradiogram and scroll down.

For listeners in Europe, there may be a few more chances to tune in the Sunday 0800-0830 UTC transmission on 5850 and/or 7730 kHz from WRMI Florida. Soon there will be too much sunlight over the north Atlantic for those frequencies (directed to Asia-Pacific) to be heard in Europe.

Videos of last weekend’s Shortwave Radiogram (program 193) are provided by Scott in Ontario (Sunday 0800 UTC on 5850 kHz) and Frigid RF in Virginia (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

This weekend we will transmit a web page in html format.  It will require some participation on your part.

Here are the instructions that will be transmitted just before the html …

    Next, the news story “Light unbound: Data limits could vanish
with new optical antennas.” It is formatted in html.  

    When all of the text is in the receive pane, copy all of it –
including the <!DOCTYPE html> at the beginning and the </html> at
the end – to a text editor.  For this, use a text editor such as
Notepad, not a word processor.  

    In Fldigi, it might be easier to Select All, then Copy to the
text editor, then in the text editor delete everything before
<!DOCTYPE html> and after </html>.

    Save the resulting file with any name you want, with the suffix
.htm or .hmtl. For example, swrg194.html.

    Then open the file in your web browser. (For many browsers in
Windows, use Ctrl-O to do this. You could also open the file in
Windows File Explorer, and it will open in your default browser.)  

    You can wait until after the broadcast to do all of this.

If any of the html code is garbled during reception, the web page could look rather strange. Part of the fun.

Here is the lineup for Shortwave Radiogram, program 194,  5-7 March 2021, in MFSK modes as noted:

“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. It’s transmitted on WRMI, Thursdays at 0200-0300 UTC on 5850 kHz (Wednesday evening in the Americas) and a new time also on WRMI, Wednesdays at 2100-2200 UTC on 7780 kHz (aimed towards Europe) . Also look for a waterfall ID at the beginning of the show. thisisamusicshow@gmail.com .  www.twitter.com/ThisIsAMusicSho/ @ThisIsAMusicSho

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 radiogram@verizon.net , 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.                

George in Greece used MultiPSK to decode the 0800-0830 UTC transmission, 7730 kHz from WRMI Florida, received via SDR in Missouri. (Good results, but a sample rate correction is needed. I have not yet attempted such a correction using MultiPSK.) …
