Shortwave Radiogram, del 1 al 6/9: programa 270

The Mighty KBC moves to its winter frequency of 5960 kHz this weekend: UTC Sunday 0000-0200 UTC, Saturday evening in the Americas. See KBC section farther down in this email  …

September is here. Here in the Washington DC area, September is usually just another month of summer, as far as the weather goes. That said, we are enjoying a few days’ respite from the extreme heat and humidity, enough to give the AC a rest and open the windows. Condolences to our listeners in western North America, where the heat dome is settling in for a few days. I’m sure some of that heat will eventually make its way east, including to our Atlantic seaboard.

At the suggestion of Mark Hirst, our audio archivist, this weekend we will try some Korean text. Unlike our English text, where line breaks are inserted at 65 spaces, we will let Korean text flow without breaks. Fldigi or your Android app will do the wrapping. We’ll see how well this works. The headline of the VOA Korean story should look like this …

This weekend’s will include eleven images. Eleven, as a prime number, is difficult for the display of images in a word processing table, which must be x times y, or y times x. Probably an arrangement with different numbers of images per row. A good challenge for an old brain.

A video of last weekend’s Shortwave Radiogram (program 269)  is provided by Scott in Ontario (Friday 1300 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Here is the lineup for Shortwave Radiogram, program 270, 1-6 September 2022, in MFSK modes as noted:

“This is a Music Show” Most of the show is a music show, but the host transmits some MFSK-64 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). Also look for a waterfall ID at the beginning of the show.    @ThisIsAMusicSho
