Shortwave Radiogram, 12-14 March 2021: Tweaking our html transmission

This weekend begins the dreaded seasonal changing of the clocks. Most of North America will move clocks forward one hour at 2:00 am local time on Sunday. On the frequencies used by WRMI for Shortwave Radiogram on Sunday, the UTC times remain the same. This means that in most states and provinces, Shortwave Radiogram will be one hour later by local time. For the Eastern time zone, the new local times are Sunday 4:00 am EDT and 7:30 pm EDT.

Videos of last weekend’s Shortwave Radiogram (program 194) are provided by Ralf in Germany (Friday 1300, excerpt with TIVAR), Jeremy in Ontario (Saturday 0100 using MultiPSK), 2010DFS in Japan (amazing reception Sunday 0800 UTC on 7730 kHz), and Scott in Ontario (Sunday 2330 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Last weekend’s transmission of the web page in html format was mostly successful. A good example is provided by Kapazitätsdiode in Germany.

There were a few instances of visible html code, and some words with spaces in the middle. The was usually not due to reception but to the way Fldigi breaks lines of text in the receive pane. For this week’s program, I will insert line breaks (<CR><LF>’s) at 65 spaces, just as I do with plain text news stories. This, along with a few manual tweaks, should eliminate those anomalies in the web page.

Here are the instructions (same procedure as last weekend) that will be transmitted this weekend:

    Next, the news story “Ample launches automated battery swap station
to help drive EV adoption.” 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, swrg195.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.  

Download Flmsg. Starting next weekend  (18-21 March), you will not have to assemble your own web page. We will use the program Flmsg with Fldigi to transfer a compiled and named html file to your computer. You can download Flmsg from here.

This weekend’s show is in the usual MFSK32 and MFSK64, with nine MFSK64 images.

Here is the lineup for Shortwave Radiogram, program 195, 12-14 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. . @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 , 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.
